          Gina L. Miller filed suit against AAA New Mexico, alleging disparate
    
    treatment on the basis of gender and age, in violation of Title VII of the Civil
    
    Rights Act of 1964, 42 U.S.C. § 2000e et seq. (Title VII), and the Age
    
    Discrimination in Employment Act, 29 U.S.C. § 621 et seq. (ADEA), and
    
    retaliation under Title VII, the ADEA, and New Mexico state law. She also
    
    asserted a claim under the Equal Pay Act, 29 U.S.C. § 206(d) (EPA), along with
    
    state law claims for breach of an implied employment contract and breach of the
    
    covenant of good faith and fair dealing. The district court dismissed Ms. Miller’s
    
    discrimination, retaliation, and EPA claims on summary judgment. 1 Her implied
    
    contract and breach of the covenant of good faith and fair dealing claims
    
    proceeded to trial, but the jury was unable to reach a verdict. The court declared
    
    a mistrial, and subsequently entered judgment as a matter of law on behalf of
    
    AAA New Mexico. Ms. Miller appeals the district court’s rulings. We affirm.

          Ms. Miller’s two basic contentions on appeal are that the district court

    judgments are highly similar and require that we view the facts in the light most
    
    favorable to the non-moving party. See Coldesina v. Estate of Simper, 407 F.3d
    
    1126, 1130-31 (10th Cir. 2005) (reviewing grant of summary judgment de novo,
    
    and construing facts in light most favorable to non-moving party); Tyler v.

    judgment as matter of law de novo, and viewing evidence and inferences drawn
    
    therefrom in favor of non-moving party). Under these required standards, the
    
    record reflects the following.
    
          Ms. Miller began working for AAA New Mexico 2 in August 1996 as a part-
    
    time traffic reporter. Her position was officially classified as “senior clerk” and
    
    she was paid on an hourly basis. 3 Ms. Miller reported directly to Brenda Yager,
    
    manager of the Public and Government Affairs (PGA) department. At the start of
    
    her employment, Ms. Miller received a copy of the AAA New Mexico Handbook
    
    which detailed that her employment was at-will. The handbook also contained a
    
          2
           AAA New Mexico is the wholly owned subsidiary of AAA Club Services,
    Inc. AAA Club Services, Inc., in turn, is the wholly owned subsidiary of the
    Automobile Club of Southern California. The Automobile Club of Southern
    California oversees the work of AAA organizations in New Mexico, Hawaii,
    Texas, and California.
    
          AAA New Mexico has both hourly and salaried employees. Salaried
          3
    
    employees are deemed to hold “regular” positions and can be full-time or part-
    time. However, only regular employees receive benefits. When Ms. Miller began
    her employment with AAA New Mexico, she understood that as an hourly
    employee she was not entitled benefits.
    
    
                                             -3-
    disclaimer stating in part: “This at-will employment relationship may not be
    
    modified by any oral or implied agreement. No provision of this employee
    
    handbook, including the Involuntary Termination section . . . or of any Club
    
    policies shall create any contractual obligations inconsistent with the at-will
    
    nature of the employment relationship.” App., vol. VII at 1369-70.
    
          About three months after Ms. Miller began working for AAA New Mexico,
    
    Ms. Yager asked if she would be interested in working extra hours performing
    
    public relations duties at her current rate of pay. Ms. Miller agreed.
    
    Acknowledging the extra duties Ms. Miller had assumed, Ms. Yager gave her
    
    permission to call herself a “Public and Government Relations Specialist.” Ms.
    
    Yager also had Ms. Miller distribute a memorandum to the rest of the AAA New
    
    Mexico staff indicating she had taken on additional duties, in conjunction with
    
    her traffic reporting duties, in the department. 4
    
          Sometime during the early part of 1997, Ms. Miller asked Ms. Yager
    
    whether she was working outside the scope of her official job description as a
    
    
          4
            At some point during her employment with AAA New Mexico, Ms. Miller
    also began to refer to herself as “lead traffic reporter.” Ms. Yager did not object
    to Ms. Miller using this title. While Ms. Miller was not in charge of the other
    traffic reporters, she did take on the responsibility of scheduling and training the
    other reporters, as well as maintaining a resource notebook for the department.
    She also had “direct contact with affiliates . . . [and] she was actually responsible
    for working with them to put together their contracts.” App., vol. II at 274. This
    included filling in forms from AAA New Mexico’s legal department, and then
    having any final negotiations approved by Ms. Yager.
    
                                               -4-
    part-time traffic reporter/senior clerk, and whether she was being paid
    
    appropriately. As Ms. Miller eventually testified at trial, Ms. Yager agreed that
    
    she was “working outside [her] job description at the time, and . . . agreed that the
    
    position should be graded higher, classified at a higher rate of pay.” Id., vol. III
    
    at 640. In response to Ms. Miller’s query as to how or whether this could be
    
    rectified, Ms. Miller testified Ms. Yager told her
    
          not to worry, because the company was going through some changes
          and they were actually getting ready to evaluate positions throughout
          the company and that there was a good chance that the position was
          going to be reclassified, in fact, would be reclassified at that time
          and graded at a higher . . . rate.
    
    Id. at 642.
    
          In April 1997, Ms. Yager had Ms. Miller fill out two different job
    
    questionnaires for a job study. One questionnaire was for her position as part-
    
    time traffic reporter, and the other was to detail her public affairs duties. Ms.
    
    Yager stated that the questionnaires were to be used by human resources in the
    
    California main office to evaluate and reclassify positions. 5 She expected the
    
    
          5
           All of AAA New Mexico’s human resources functions were housed in and
    provided for by the Automobile Club of Southern California. The parent
    organization set “all of the human resource policies, benefits, compensation,
    salary grades, [and] titles,” id., vol. IV at 855, 1032, for its subsidiary companies.
    In order for Ms. Yager to create a regular salaried position within her department,
    she was required to seek permission from her direct supervisor to request human
    resources perform a job evaluation study. She could not unilaterally decide to
    reclassify a position or create a regular benefitted post. Rather, if the business
                                                                              (continued...)
    
                                              -5-
    review and reclassification process would take “a few weeks . . . maybe two to
    
    three months at the most.” Id. at 643. Ms. Miller anticipated that when the job
    
    study reclassification process was complete, she would receive increased
    
    compensation for her work.
    
          The job study was completed in September 1997, but to both Ms. Miller’s
    
    and Ms. Yager’s dissatisfaction, the study did not “actually take the information
    
    that Ms. Miller provided and determine whether or not her title was correct or she
    
    was being paid correctly.” Id., vol. IV at 868. Rather, the study used the job
    
    questionnaires to perform a comparison between the different state AAA offices
    
    under the auspices of the Automobile Club of Southern California to ensure the
    
    current positions in the state offices were similarly ranked. 6 It was not the type of
    
    “true job study” Ms. Yager had expected or what she “was originally told . . . was
    
    going to happen.” Id. at 867. Ms. Yager was unhappy with the results of the
    
    study, and continued to affirm to Ms. Miller that she thought Ms. Miller was
    
    performing duties outside of her job classification, and should be better
    
    
          5
           (...continued)
    needs of the department warranted reclassifying a position or creating a new one,
    a request could made for such, but any final job creation or classification decision
    had to be ultimately approved at “the executive level.” Id. at 1037, 1064; id., vol.
    VI at 1325-26.
          6
            As a result of this company wide job study, Ms. Miller’s official
    classification was changed from “senior clerk” to “clerk, intermediate.” This
    change did not affect Ms. Miller’s hourly pay rate.
    
                                             -6-
    compensated. Ms. Yager promised Ms. Miller she was going to follow up with
    
    human resources and look into the problem.
    
          On January 9, 1998, Ms. Yager sent a letter to her then direct supervisor,
    
    Steve Lenzi, urging the review of the staffing needs in her department, especially
    
    Ms. Miller’s position. Referring to the work Ms. Miller was performing as both a
    
    public relations assistant and a traffic reporter, she wrote that “[t]wo positions
    
    exist in the public and government affairs department . . . that need to [be]
    
    evaluated for correct title and salary grade.” Id. at 874; id., vol. VI at 1279. She
    
    informed Mr. Lenzi she believed the current titles and grades were inappropriate
    
    and asked that the positions be upgraded. She also noted that an upgrade of the
    
    two positions would impact Ms. Miller, who was then working about thirty-five
    
    hours a week. Mr. Lenzi gave Ms. Yager permission to contact human resources
    
    to request they perform an evaluation of her department’s needs as well as the
    
    positions for possible upgrading.
    
          Ms. Miller further testified that during the winter of 1998, Ms. Yager
    
    assured her she was continuing her conversations with human resources and that
    
    Ms. Miller “would receive an upgrade and be reclassified based on the
    
    information that [Ms. Yager] had received from her management.” Id., vol. III at
    
    657-58. Ms. Miller testified she believed an “upgrade” meant “a new job title,
    
    the correct job description,” id. at 658, and a “regular” position with full benefits,
    
    
                                              -7-
    in which she worked thirty-five hours a week. Id. at 657-58. She further testified
    
    that Ms. Yager stated the upgrade would happen “soon, within a few weeks or a
    
    few months.” Id. at 659. However, Ms. Miller was unable to testify as to the
    
    exact date of the upgrade, or the exact salary she would receive upon that date.
    
    Id.
    
           In the meantime, Ms. Yager’s supervisors indicated to her that it would be
    
    easier to provide wage increases to her employees than to go through the process
    
    of creating regular posts. Ms. Yager testified she was informed that in order to
    
    create regular posts in her department “a job study would have to be done, and
    
    that it was a very lengthy process, and if I was looking at providing increased
    
    compensation immediately, [a pay raise] was the way to do it.” Id., vol. II at 282.
    
    Ms. Yager would rather have gone through the process of obtaining regular
    
    positions, but she nonetheless increased Ms. Miller’s wage to $10.00 an hour.
    
    Upon determining that one of the employees who also received a raise had just
    
    joined the company and had been trained by Ms. Miller, Ms. Yager increased Ms.
    
    Miller’s hourly rate to $10.50, retroactive to the date of the $10.00 wage
    
    increase. 7
    
    
    
           When Ms. Miller began her employment with AAA New Mexico in August
           7
    
    1996, she earned $7.50 an hour. In February 1997, her wage was increased to
    $7.90 an hour. Then, in March 1998, her wage was raised to $10.00. She
    subsequently received the additional raise to $10.50 an hour, retroactive to
                                                                          (continued...)
    
                                             -8-
          All of Ms. Miller’s male colleagues in the PGA department were also
    
    classified as “clerk, intermediate” and worked in hourly part-time positions.
    
    There only appears to be one instance, during a three month period in 1997, when
    
    a male co-worker earned eight cents an hour more than Ms. Miller. 8 Between
    
    1998 and the spring of 2000, however, no male in Ms. Miller’s department
    
    received an hourly wage that surpassed hers.
    
          In November or December 1998, Leigh Matthewson, Ms. Miller’s mother,
    
    began working in the PGA department as a contract employee doing public affairs
    
    work. Ms. Yager eventually hired her in May 1999 in a hourly position with the
    
    official classification of “clerk, intermediate.” At the time she was hired, Ms.
    
    Matthewson said she was interested in a position with benefits but Ms. Yager
    
    informed her she did not have a regular benefitted position to offer her. At trial,
    
    Ms. Matthewson testified she agreed to work for AAA New Mexico because of
    
    her understanding that the position she would be filling was in the process of
    
    being upgraded to a regular post. She was unable to identify a specific date upon
    
    
          7
           (...continued)
    February 5 of that year. On February 28, 1999, her hourly rate was further
    increased to $10.68.
          8
           In her response to AAA New Mexico’s motion for summary judgment, as
    well as on appeal, Ms. Miller makes no reference to this apparent disparity, and
    instead asserts that her Title VII discrimination and EPA claims are based, in part,
    on the disparity in wages between her hourly rate and that of the men in her
    department from 1998 to 2000.
    
                                            -9-
    which the position would in fact be upgraded, or a date on which she would start
    
    receiving benefits.
    
          In February 1999, Ms. Yager informed Ms. Miller she was still working on
    
    obtaining the upgrade. Ms. Miller testified Ms. Yager “had promised that the
    
    upgrade process was ongoing and that [the upgrade] would happen.” Id., vol. III
    
    at 675. Ms. Yager, Ms. Miller, and Ms. Matthewson participated in a number of
    
    brainstorming sessions during which they discussed how they hoped the
    
    department might be reorganized in light of the potential upgrades. Throughout
    
    this process, Ms. Yager testified she told the two women
    
          “you know, I don’t know how much input, how much say I’m going
          to have. But certainly, let’s talk about some things that might be
          workable. And if I have input, then that’s good. Then I’m armed
          with better information and with how we think things might work
          best [for our department].”
    
    Id., vol. IV at 946.
    
          In May of that year, Ms. Yager included two regular positions in her 2000
    
    budget proposal. In submitting her budget request to her general manager, she
    
    noted that “[i]n the 2000 budget, I’ve upgraded [Ms. Miller’s] and [Ms.
    
    Matthewson’s] positions to regular employees rather than hourly. They already
    
    are working the hours (35 and 40 respectively) but they are not currently getting
    
    benefits. This is the one item that I would like to protect above others.” Id. at
    
    891; id., vol. VI at 1285. Ms. Yager testified that her manager agreed to honor
    
    
                                             -10-
    her request. 9
    
           On July 1, 1999, Ms. Yager again met with Ms. Miller and Ms. Matthewson
    
    to discuss the status of the 2000 proposed budget which included the two regular
    
    positions. Ms. Miller’s trial testimony indicated Ms. Yager informed the women
    
    “[t]he upgrades were imminent. They were going to come through any time . . . .”
    
    Id., vol. III at 678-79; id., vol. IV at 892. Ms. Yager testified that “I didn’t say
    
    that was the final word. But yes, I said it was looking good, that at least at this
    
    juncture, we had a long ways to go in the budget, but at least as of this juncture,
    
    they were in the budget.” Id., vol. IV at 891-92. She also testified that “human
    
    resources temporarily approved for the use of [the titles of Public Affair
    
    Specialists] on business cards. And I actually said to them that they may not be
    
    the job titles that we end up with, but for right now, they’re fine.” Id. at 892; id.,
    
    vol. III at 678-79. Ms. Miller and her mother were “absolutely elated because
    
    [Ms. Yager] said the positions were approved or going to be approved, just within
    
    a short period of time . . . .” Id., vol. IV at 991.
    
           Around this time, Ms. Miller raised the question of whether she would
    
    receive retroactive pay for the public affairs work she had already performed for
    
    the PGA department. She testified Ms. Yager was not clear on the answer to this
    
    
    
           Ms. Yager testified that in the last two budgetary years she had requested
           9
    
    the addition of a regular benefitted position in her department, but that her request
    was denied on both occasions.
    
                                              -11-
    question, but would look into it for her. Ms. Miller said Ms. Yager “believed I
    
    should receive retroactive compensation for the time that I have worked outside
    
    of my job description; that I had clearly been working out[side] of my job
    
    description for years . . . and that she believed I should receive retroactive
    
    compensation.” Id., vol. III at 681, 772. However, at trial Ms. Miller also made
    
    clear she had “never testified that anyone told me I was going to receive
    
    retroactive compensation.” Id. at 773. Ms. Yager also testified that upon being
    
    asked by Ms. Miller whether she would receive retroactive pay, Ms. Yager
    
    responded it “was highly unlikely that the company would consider that, but [she]
    
    wasn’t going to discount anything . . . .” Id., vol. IV at 950.
    
          Despite Ms. Miller’s and Ms. Matthewson’s belief that the position
    
    upgrades would occur soon after their July meeting with Ms. Yager, nothing
    
    happened. Later that month, Ms. Miller contacted a member of the human
    
    resources department in California and inquired as to the status of the job review
    
    process. She was informed the process had not yet begun, but that “[a]ll positions
    
    in New Mexico (as well as Texas and Hawaii) are going to be evaluated hopefully
    
    this year.” Id., vol. VI at 1287; id., vol. III at 683. Ms. Miller was “shocked and
    
    dismayed” at this response because it was her understanding that the upgrades
    
    “were just around the corner.” Id., vol. III at 683. Ms. Miller testified that in
    
    asking Ms. Yager about the delay, Ms. Yager assured her that “there was no
    
    
                                             -12-
    problem at all with the upgrade. The upgrade was going to take place. It was
    
    simply a matter of the timing . . . .” Id. at 684.
    
           Ms. Yager met with Ms. Miller and her mother again in late September
    
    1999. She said she was sorry the process was taking so long, but “[s]he was not
    
    clear about a time line . . . because she couldn’t get a time line from human
    
    resources.” Id. at 687. In an effort to garner more information about the job
    
    evaluation process, Ms. Matthewson contacted human resources in October. The
    
    response from the human resources staff member indicated that
    
           [a]s far as I know, those positions are being looked at and it is
           expected that they will be upgraded to reflect more of your current
           duties. Those positions will not be even looked at until next month
           sometime, and should be completed prior to January. When the study
           is done it is expected that they will include the items you mentioned
           including job description, status and compensation. . . . Since they
           have not even been started yet, it is hard for me to give you much
           more info. Our compensation department will be working on them
           along with your local management and Public Affairs management
           here in California. Hope this helps – currently I don’t have more
           definitive answers.
    
    Id., vol. VI at 1289; id., vol. III at 689. Ms. Miller and her mother were “shocked
    
    [and] upset,” id., vol. III at 689, by the response, and could not understand why
    
    the process was taking so long “especially when [Ms. Yager] had adamantly said
    
    that she had submitted all the paperwork necessary and that the job upgrade was
    
    just around the corner . . . .” Id. at 690.
    
           Ms. Yager was equally “devastated” to learn the upgrade review process
    
    
                                                  -13-
    was so delayed. Id., vol. IV at 894. She testified it was her “understanding, at
    
    least in the fall of 1999, that [human resources] was, in fact, working on [the]
    
    positions,” id. at 893, and it was her belief that completion of the process “was
    
    imminent.” Id. at 894. Her perception from speaking with staff in the human
    
    resources department was that “everything was on track for the job study to be
    
    completed by the end of the year.” Id. at 947. Hence, she was “upset” to learn
    
    that the process “had not even been started yet.” Id. at 894. It was very
    
    important to her that the regular positions be created because she had “been
    
    telling Ms. Matthewson and Ms. Miller that the process was happening and it
    
    would be soon” and “that the job study would be completed by the end of the
    
    year.” Id.
    
           Ms. Yager had another meeting with Ms. Miller and her mother during the
    
    first week of November to further discuss the upgrade process. Ms. Yager
    
    confirmed that at the meeting Ms. Miller stated she “thought the company was not
    
    treating her equitably . . . it wasn’t fair . . . [and] was discriminatory.” Id., vol. II
    
    at 289. In an affidavit, Ms. Miller also stated she
    
           knew that the traffic reporters were paid nearly the same that [she
           was], but the traffic reporters did not perform any “lead” traffic
           reporting duties and did not perform public affairs specialist duties.
           It seemed very unfair and [she] could not find any other explanation
           for these differences except [her] sex . . . . [She] complained to [Ms.
           Yager] that [she] thought what the company was doing was
           discriminatory, that it was not right, and that it was unfair.
    
    
                                               -14-
    Id. at 340; see also id. at 289-90 (Ms. Miller stated her “pay was unfair compared
    
    to the men in the department”). Ms. Yager informed the Human Resources
    
    department that Ms. Miller “thought she was being treated unfairly, that she was
    
    being discriminated against, and that she thought she was being treated differently
    
    than male employees.” Id. at 290.
    
          On November 17, Ms. Yager met with Alice Bisno, her then direct
    
    supervisor, and two other members of the human resources department, to discuss
    
    her request to create two new regular positions in her department. While Ms.
    
    Yager had previously discussed the upgrade requests with Ms. Bisno, the meeting
    
    “was the first time [they] actually talked about possible ways to reorganize” the
    
    department. Id., vol. IV at 896. Ms. Yager testified that her understanding of the
    
    purpose of the meetings, as well as her request for upgrades, was to move the jobs
    
    from “hourly position[s] to . . . regular position[s].” Id. at 897. She did not recall
    
    ever directly engaging in a conversation about eliminating Ms. Miller and Ms.
    
    Matthewson’s hourly positions, nor was a “conscious decision” ever made in this
    
    regard. Id., vol. I at 156. Rather, she and her colleagues “looked at what the
    
    business needs of the operation were and we decided that those two part-time
    
    positions were not serving the needs of the department and that we needed two
    
    full-time positions. And it was my understanding that that’s what the two
    
    employees were requesting as well.” Id.; see also id., vol. II at 298-300; id., vol.

    IV at 898-99. 10
    
          On December 15, 1999, Ms. Miller and her mother again met with Ms.
    
    Yager to inquire as to the status of the review process, and whether they would be
    
    classified as regular employees by Christmas so that they could take paid vacation
    
    over the holidays. Ms. Yager “told [them] there was no news . . . that the upgrade
    
    process had still not been completed, and it would be maybe sometime in January
    
    before . . . she could give [them] a final [report] on the upgrade completion.” Id.,
    
    vol. III at 694. Ms. Yager apologized to the women for length of time it was
    
    taking to complete the process. Ms. Miller testified that “she said, ‘I believe what
    
    the company is doing is morally wrong, and I don’t agree with it, and I’m really
    
    sorry. And if you can just hang on a little bit longer, it’s going to come through.
    
    I promise you.’” Id. at 696.
    
          After the holidays, Ms. Miller testified that Ms. Yager was unable to
    
    provide the two women with any further information about the job evaluation
    
    process. Ms. Miller stated that upon asking Ms. Yager “when [she and her
    
    mother] could expect the upgrade . . . her response . . . was ‘I have no idea. I
    
    have no idea.’” Id. at 702. On January 31, 2000, Ms. Miller again met with Ms.
    
    Yager. At that meeting, Ms. Yager indicated that
    
    
          10
            Ms. Yager also affirmed that she was not in charge of how the upgrade
    process would proceed, and that “every step of the way, [she called] human
    resources and follow[ed] their direction.” Id., vol. VI at 907.
    
                                            -16-
          she didn’t have any further answers for me at that time. She told me,
          encouraged me to talk to human resources about all of my concerns,
          because she didn’t feel like she could answer those questions. She
          still told me that the upgrade was a certainty. That wasn’t the issue.
          The issue was when it was going to be completed. . . . And then . . .
          we talked about the retroactive compensation . . . . [a]nd she said that
          she thought that I should receive the retroactive compensation.
    
    Id. at 706.
    
          Soon after that meeting, Ms. Miller and her mother learned they would be
    
    meeting with Ms. Yager and Ms. Bisno to address their employment concerns. In
    
    preparation for the meeting, Ms. Miller sent a memorandum to Ms. Bisno stating
    
    she hoped Ms. Bisno could “provide a detailed status report on our forthcoming
    
    job upgrades.” Id., vol. II at 379. She noted that while she understood the new
    
    job title for the upgraded position would be “Public Affairs Specialist II,” she still
    
    had “no idea of the job responsibilities and parameters” of the position. Id. She
    
    further inquired as to what the “‘grade’ classification and salary band” was for the
    
    proposed new post. Id. She also stated “[i]n that it is illegal to do so, how am I
    
    to continue performing daily job duties outside of my classification, as I’ve done
    
    for over three years, without any promise of good faith or compensation on the
    
    part of the company?” Id. at 380.
    
          Ms. Bisno, along with Ms. Yager, met with Ms. Miller and her mother in
    
    New Mexico on February 10, 2000. Ms. Bisno informed the women that as a
    
    result of the job study, their current part-time hourly positions were being
    
    
                                             -17-
    eliminated, and replaced by two new full-time regular positions. At that time,
    
    neither Ms. Bisno nor Ms. Yager knew “what the compensation for the position[s]
    
    would be.” Id., vol. III at 714.
    
          Pursuant to AAA New Mexico policy, the new positions had to be posted
    
    and Ms. Miller and her mother would have to apply for them. 11 They were
    
    encouraged to apply for the new positions, but were also told there were no
    
    absolute guarantees they would be selected. The women were informed they
    
    would not receive any retroactive pay for the public relations duties they had
    
    performed under their “clerk, intermediate” titles. Id. at 717. Nonetheless, Ms.
    
    Miller stated that Ms. Bisno “said she would promise to investigate our concerns
    
    and our complaints about discrimination.” Id., vol. II at 347. 12
    
          11
            Ms. Yager testified she asked Clarence Sandy, a human resources staff
    member for the Automobile Club of Southern California who was assigned to
    human resources for AAA New Mexico, about the posting process for the new
    positions. He informed her Ms. Miller and her mother would have to apply for
    them. She indicated Ms. Miller and Ms. Matthewson would probably be unhappy
    to learn about the posting requirement, but he responded “[t]hat it was company
    policy that any new position in the company needed to be posted.” Id., vol. II at
    299; see also id. at 302.
           There existed only two exceptions to AAA New Mexico’s new job posting
    requirement. First, if an individual’s position was “being phased out through the
    Staff Reduction Program,” id. at 389, “they have to be given first consideration,
    [and second,] . . . if someone is returning from a medical leave, then they’re also
    given first consideration.” Id., vol. VI at 1042; id., vol. II at 389.
    
           Ms. Bisno testified her initial understanding of Ms. Miller and her
          12
    
    mother’s concerns regarding “discrimination” was that “perhaps other employees
    were being treated better.” Id., vol. II at 327. She stated she knew the women
                                                                          (continued...)
    
                                            -18-
          Ms. Yager was involved in drafting the job descriptions for the new
    
    positions. She maintained that they were not written with any one person in mind
    
    but instead were based on the business needs of her department. As she testified
    
    at trial, she and her colleagues
    
          looked at the needs of the department and wrote the job description around
          that. And when [she eventually] shared the job description with [Ms.
          Miller], [she] told her . . . “We can’t write this job description specifically
          for you, because when you leave the company, then we have a job
          description that fits you but not the needs of the business. And so what we
          have to do is write the job description so it fits the need of the business and
          choose the most qualified candidate.”
    
    Id., vol. IV at 925. She also testified that if Ms. Miller had applied for job, she
    
    would have considered her for the position because she “was the most qualified
    
    candidate.” Id. at 927. She commented that
    
          [e]ven though . . . there were additional things in the job description
          that [Ms. Miller] hadn’t done before, I felt that it was something that
          she could do. She could learn many of those things that she hadn’t
          done in the past, and even though we were changing the focus of the
          job from . . . the primary focus before was traffic reporting and we
          were actually changing that to become a very minor part of the job
          and the public affairs piece was the greater piece, I felt [Ms. Miller]
          could do the job.
    
    Id., vol. II at 300. Ms. Yager also noted that while the new position required
    
    
    
          12
            (...continued)
    were dissatisfied with issues regarding their pay, benefits, and job titles. Id. at
    322. However, it was not until after both Ms. Miller and Ms. Matthewson left
    AAA New Mexico that she came to understand their claims of discrimination
    were grounded on “some protected basis.” Id. at 322, 327.
    
                                             -19-
    some heavy lifting, she had previously made accommodations for Ms. Miller in
    
    this respect in her hourly position and would do the same in the new job.
    
          The new jobs were not merely reclassified positions representing the work
    
    previously being performed by Ms. Miller and her mother. Rather, they included
    
    “everything they were doing plus things.” Id., vol. IV at 903, 918. Ms. Yager
    
    noted that her department’s needs included positions in which the employees
    
    could devote more hours to their tasks as well as perform additional job duties.
    
    For example, she needed someone to act as an advocate on behalf of the company.
    
    Ms. Yager commented that “[w]e analyze information, and based on the
    
    information we analyze, propose legislation. So I certainly wanted [someone
    
    doing legislative advocacy work].” Id., vol. II at 294. She also stated she needed
    
    “someone to be able to synthesize, research and be able to come up with programs
    
    based on research.” Id.
    
          In regard to the position best suited for Ms. Miller, Ms. Yager testified
    
    there were several aspects of the new job Ms. Miller did not perform as an hourly
    
    employee. 13 In reviewing the job description for the new post, Ms. Yager noted
    
    Ms. Miller
    
    
          13
            When asked to compare Ms. Miller’s performance of public affairs duties
    against that of a job description for a similar regular post at the Automobile Club
    of Southern California, Ms. Yager testified that under that job description, Ms.
    Miller was not fulfilling all the duties that would be expected of a full-time
    regular Public Affairs Specialist.
    
                                            -20-
          wasn’t developing strategic approaches to project assignments. She
          was doing limited research and investigation. She was not providing
          technical authoritative information resource. She was not . . .
          [c]omp[iling] and synthesiz[ing] information . . . . [S]he was not
          evaluating “research findings and interpret[ing] for policy
          development.” She was not tailoring “research results to become
          [an] advocacy tool in [the] public forum. She was not recommending
          “strategies and issues to management for policy development.” She
          was doing very limited “influenc[ing] and persuad[ing] policy of
          affiliate organizations.” . . . She was not . . . [acting as an] “advocate
          within coalitions to further organizations, member and insured
          interests.” She was not interpreting and refining “policy
          incorporating affiliate and organizational feedback.”
    
    Id. at 294-95. None of these tasks had previously been assigned to Ms. Miller in
    
    her hourly position. Rather, Ms. Yager had been performing the tasks herself.
    
    Likewise, there were duties inherent to a regular public relations position, like
    
    being on-call for the company, that Ms. Miller was not performing.
    
          Ms. Miller and her mother sent a memorandum to Ms. Bisno soon after the
    
    February 2000 meeting outlining their understanding of what transpired and
    
    asking a series of follow-up questions. Id., vol. VI at 1298-1300. Nothing in the
    
    memorandum alleged discrimination based on protected status. On February 24,
    
    Ms. Bisno informed Ms. Yager and the other human resources staff members
    
    involved in the restructuring of Ms. Yager’s department that she
    
          did not intend to respond to the memo . . . it’s all the same issues
          discussed at our meeting in New Mexico. The employees simply do
          not like the answers they got and, until we come to some resolution, I
          don’t intend to change them and don’t see much value in repeating
          them.

    Id., vol. II at 381; see also id. at 332.
    
           In early March 2000, Ms. Miller had a meeting with Clarence Sandy, the
    
    human resources staff person assigned to AAA New Mexico, to “address some of
    
    [her] concerns over departmental inequities as they relate to job title, description,
    
    status, compensation and benefits.” Id. at 384. In a follow-up memorandum
    
    memo to Mr. Sandy, Ms. Miller noted that all the male traffic reporters hired in
    
    the PGA department had started at higher rates of pay than her starting rate of
    
    pay, even though they came to the job “with little or no broadcast experience.”
    
    Id. at 385. She further asserted that
    
           I currently make a few cents more per hour than the two other Traffic
           Reporters I trained and continue to manage, both men. I perform
           “LEAD Traffic Reporter” operational duties while wearing the
           second hat of “Public Affairs Specialist,” while these other
           employees do nothing more than come and go to report traffic on a
           part-time or back-up basis.
    
    Id. While she understood that “club policy on compensation and benefits can vary
    
    widely from department to department within the company,” id. at 386, she
    
    nonetheless believed that “this type of arbitrary allocation [where she was
    
    working 35 hours a week, but still being paid as a part-time hourly employee]
    
    appears unusual in [her] experience and because it is arbitrary – inherently
    
    discriminatory.” Id. 14 She also stated that as a result of the company’s
    
    
           14
                Ms. Matthewson sent a similar e-mail message to Ms. Yager on March 13,
                                                                          (continued...)
    
                                                -22-
    “inequities and inconsistencies . . . in compensation,” she
    
          felt particularly exploited. It’s led me to believe, after having
          forthrightly expressed my concerns to [Ms. Yager] over the years
          about compensation, lack of communication and direction, etc., that
          the treatment I’ve received in this department as to compensation and
          the denial of benefits, is egregiously unfair, retaliatory and
          discriminatory.
    
    Id. at 385.
    
          In response, Mr. Sandy testified that “none of [Ms. Miller’s] statements . . .
    
    would fit ‘discriminatory’ because hourlies don’t have benefits unless you became
    
    a regular employee.” Id., vol. I at 214. He also testified that in response to Ms.
    
    Miller’s allegation as to discriminatory payment practices in the PGA department,
    
    he examined the departmental file but found Ms. Miller was making more than
    
    any of the other men in her department. Hence, he determined there was “really
    
    nothing there to support [a] discrimination [charge].” Id.
    
    
    
          14
              (...continued)
    2000, stating she and Ms. Miller were
            disadvantaged as compared to you and the majority of AAA New
            Mexico employees who enjoy full benefits. . . . Of course, it is easy to
            see that the results of these inequities have created a condition which
            results in discrimination. I would think that the company would want
            to administer their wages and benefits consistently from department to
            department to eliminate the injustices [Ms. Miller] and I have
            suffered.
    Id. at 382. Ms. Matthewson was eventually dismissed from her position. Ms.
    Yager testified that Ms. Matthewson was insubordinate and created a hostile
    working environment by refusing, among other things, to perform certain job
    duties asked of her.
    
                                             -23-
          Ms. Yager usually met with her staff for annual employee evaluations in the
    
    early spring, but she did not engage in a performance review with Ms. Miller in
    
    February 2000. She testified that Ms. Miller’s
    
          performance had not been good, but I certainly understood, and
          wanted to be fair to her. She was very upset about the situation and I
          understood her being upset with [the new job creation process]. It
          took longer than any of us had ever anticipated, and I didn’t think it
          would be fair to her to do an evaluation at that point. . . . [S]he had
          spent all of her time writing all of these memos [regarding the
          position evaluation process] and doing all this stuff . . . [so] I didn’t
          think that [it] was fair to review her in this time period.
    
    Id., vol. II at 304-05. She also noted that within a week of the meeting with Ms.
    
    Bisno, Ms. Miller protested being evaluated in light of her unresolved questions
    
    regarding the reorganization of the department and the new public affairs
    
    position. Ms. Yager did perform an evaluation, however, for one of the men in
    
    the department, who subsequently received a wage increase.
    
          Ms. Miller declined to apply for the new position. At trial, she explained
    
          I knew that they wanted me out, and they were going to get rid of me
          no matter what. So I knew they had already made up their minds,
          that no matter what hoops I jumped through to apply for this
          position, I was not going to get the position. But beyond that . . . I
          would have not been eligible for the position by a couple of criteria.
    
    Id., vol. III at 738-39. In particular, Ms. Miller contended she did not meet two
    
    of the qualifications listed for the new post: a minimum of five years experience
    
    and a lifting requirement. Therefore, she thought that even if she applied for the
    
    post, it would not have been offered to her. Ms. Yager testified to the contrary
    
                                             -24-
    that Ms. Miller was “way over” qualified for the position in light of her work
    
    experience prior to joining AAA New Mexico. Id., vol. IV at 923. Moreover, as
    
    referenced earlier, the company had already made accommodations to Ms. Miller
    
    regarding her lifting limitations, and would have done the same for her in the new
    
    post.
    
            In light of Ms. Miller’s decision not to apply for the new position, Ms.
    
    Yager contacted Mr. Sandy, who informed her that “once the full-time position
    
    was filled . . . the other position . . . would end.” Id., vol. II at 310. After a
    
    number of conversations between Ms. Miller and Ms. Yager, it was decided that
    
    Ms. Miller’s last day of work would be May 5, 2000. Ms. Miller ended her
    
    employment with AAA New Mexico on that day. After screening applicants for
    
    the newly-created position, AAA New Mexico offered the job to a female
    
    applicant. That applicant declined the company’s offer. AAA New Mexico then
    
    offered the position to a male, Dan Ware, who accepted the job at an annual
    
    starting salary of $35,000.
    
            Ms. Miller filed this action in federal district court against AAA New
    
    Mexico. As relevant to this appeal, she claimed the company discriminated
    
    against her in violation of Title VII and the EPA. She specifically alleged AAA
    
    New Mexico did not adequately pay her for the work she was performing as
    
    compared to the compensation of men in her department, and that the company
    
    
                                               -25-
    paid the man who was offered the new position substantially more than she had
    
    been earning doing the same job. She also asserted she suffered retaliatory
    
    discharge under state and federal law when the company, in response to her
    
    allegations that she was being discriminated against on the basis of her sex,
    
    eliminated her position and forced her to apply for the newly created position.
    
    Finally, she brought New Mexico state law claims for breach of implied contract
    
    and breach of the covenant of good faith and dealing. These claims were
    
    premised on her assertion that AAA New Mexico promised she would
    
    automatically be placed in the upgraded position, but had, in bad faith, failed to
    
    do so.
    
             A magistrate judge handled the initial stages of Ms. Miller’s litigation,
    
    including the discovery process during which Ms. Miller and the company had
    
    some disputes. AAA New Mexico eventually moved for summary judgment on all
    
    of Ms. Miller’s claims. The district court granted summary judgment on Ms.
    
    Miller’s Title VII and EPA discrimination claims as well as her federal and state
    
    retaliation claims. The remaining claims proceeded to trial. After both parties
    
    presented their evidence, AAA New Mexico moved for judgment as a matter of
    
    law. The district court reserved its ruling on this matter and the case was
    
    submitted to the jury. The jury was unable to reach a verdict, and the court
    
    declared a mistrial. The company renewed its motion for judgment as a matter of
    
    
                                               -26-
    law, which the district court subsequently granted. Ms. Miller now raises a host
    
    of challenges to the district court’s rulings.
    
    
    
                                               II
    
          In order to address Ms. Miller’s challenge to the district court’s grant of
    
    summary judgment on her discrimination and retaliation claims, we must also
    
    disentangle a knotty discovery issue Ms. Miller raises. She requests that we
    
    reverse a ruling of the magistrate judge denying her motion to compel AAA New
    
    Mexico to produce specific documents and answer interrogatories. On appeal, she
    
    contends the evidence denied to her by the magistrate judge’s ruling undermined
    
    her ability to sufficiently challenge AAA New Mexico’s motion for summary
    
    judgment. Ms. Miller’s appeal of the magistrate judge’s ruling is thus
    
    inextricably intertwined with her challenge to the district court’s summary
    
    judgment ruling.
    
          As we discuss in more detail throughout this section, we determine the
    
    district court implicitly rejected Ms. Miller’s challenge to the magistrate judge’s
    
    ruling. So doing, and in the course of concluding the district court did not err in
    
    granting summary judgment to AAA New Mexico, we also conclude the district
    
    court did not abuse its discretion in rejecting Ms. Miller’s challenge to the
    
    magistrate judge’s decision. Because our resolution of Ms. Miller’s discovery
    
    
                                              -27-
    claim is best understood in light of our examination of the district court’s grant of
    
    summary judgment, we will address her challenges to the summary judgment
    
    ruling and intersperse within our analysis the relevant aspects of her discovery
    
    issues.
    
          As mentioned earlier, “we review a grant of summary judgment de novo,
    
    applying the same legal standard as the district court.” Coldesina, 407 F.3d at
    
    1131 (citation omitted). Summary judgment is appropriate “if the pleadings,
    
    depositions, answers to interrogatories, and admissions on file, together with the
    
    affidavits, if any, show that there is no genuine issue as to any material fact and
    
    that the moving party is entitled to a judgment as a matter of law.” F ED . R. C IV .
    
    P. 56(c). “When applying this standard, we view the evidence and draw
    
    reasonable inferences therefrom in the light most favorable to the nonmoving
    
    party.” Steele v. Thiokol Corp., 241 F.3d 1248, 1252 (10th Cir. 2001).
    
    
    
          A. Title VII discrimination claim
    
          Pursuant to Title VII, Ms. Miller alleged she was compensated worse than
    
    similarly situated male employees. We apply the McDonnell Douglas Corp. v.
    
    Green, 411 U.S. 792, 802 (1973), framework for evaluating Title VII claims. See
    
    Garrett v. Hewlett-Packard Co., 305 F.3d 1210, 1216 (10th Cir. 2002); Bullington
    
    v. United Air Lines, 186 F.3d 1301, 1315 (10th Cir. 1999), overruled on other
    
    
    
                                              -28-
    grounds sub nom. by Boyler v. Cordant Techs., Inc., 316 F.2d 1137, 1140 (10th
    
    Cir. 2003). Under McDonnell Douglas, Ms. Miller is required to first establish a
    
    prima facie case of discrimination. In this context, we have stated “a female Title
    
    VII plaintiff establishes a prima facie case of sex discrimination by showing that
    
    she occupies a job similar to that of higher paid males.” Sprague v. Thorn Ams.,
    
    Inc., 129 F.3d 1355, 1363 (10th Cir. 1997) (citing Meeks v. Computer Assocs.
    
    Int’l, 15 F.3d 1013, 1019 (11th Cir. 1994)). The district court determined Ms.
    
    Miller failed to make out a prima facie case. We agree.
    
          Ms. Miller contends there was a disparity in pay between what she received
    
    and how the other men in the PGA department were compensated. She also
    
    claims there was a disparity in compensation between what she was paid for doing
    
    public affairs duties and what was paid to the man who was hired for the new
    
    position. She has not established a prima facie case of gender discrimination with
    
    respect to either of these claims.
    
          First, Ms. Miller has not shown that she was paid less than any of the other
    
    men in the PGA department. As noted earlier in the opinion, she and her male
    
    colleagues in the PGA department were all classified in the same manner and
    
    none of the men in the department ever earned more than she did barring a three
    
    month period in 1997 during which one man earned eight cents an hour more.
    
    Ms. Miller makes no effort to undermine these facts. Instead, she argues that
    
    
    
                                            -29-
    because she was performing additional public affairs duties as well as serving as
    
    “lead traffic reporter” for the PGA department, her rate of pay should have been
    
    substantially higher than that paid to the men in her department, who were only
    
    performing traffic duties. While this may be true, her argument is not that she
    
    was working the same hours as these men during which time she was doing far
    
    more work but only getting paid marginally more. Instead, the record reflects she
    
    was working thirty-five hours a week while the men in her department were only
    
    working fifteen hours a week. 15 While it is uncontested Ms. Miller performed
    
    more duties than the men in her department, she worked more hours than they did
    
    and was compensated at a slightly higher rate than they were. Hence, Ms. Miller
    
    has not shown she “occupied a job similar to that of higher paid males.” Id.
    
          Nor can Ms. Miller establish her prima facie case by arguing there was
    
    disparity in the pay she received and that paid to the man who accepted the new
    
    post. She essentially argues she was replaced by Mr. Ware, who then earned
    
    substantially more than she did for performing the same work. On these grounds,
    
    she appears to argue she was treated less fairly than a similarly situated employee.
    
          But Ms. Miller and Mr. Ware were not similarly situated employees
    
    because they held two different positions. First, Ms. Miller was an hourly part-
    
    
          15
             In her March 2000 memorandum to Mr. Sandy, Ms. Miller commented
    that the male employees “do nothing more than come and go to report traffic on a
    part-time or back-up basis.” Id. at 385; see also Aplt. Reply Br. at 21-22.
    
                                            -30-
    time employee who performed a variety of traffic reporting and public affairs
    
    duties. Conversely, Mr. Ware filled a newly-created, full-time, regular position.
    
    Second, while there is no question Ms. Miller performed some of the duties that
    
    were included within the job description for the new post, the record indicates
    
    there were a number of central components of the new job that Ms. Miller did not
    
    perform in her capacity as “clerk, intermediate.” Her case is similar to the female
    
    employee in Sprague who took on some advanced duties similar to those
    
    performed by other higher paid men in her company, but could not show that she
    
    “de facto” held the same position as the men. Id. at 1359, 1363. In like fashion
    
    to the employee in Sprague, Ms. Miller cannot show she was similarly situated
    
    with Mr. Ware such as to make out a discrimination claim. Her status as an
    
    hourly employee and the duties she performed in that position are not sufficiently
    
    similar to the position held by Mr. Ware. We therefore agree with the district
    
    court’s conclusion that Ms. Miller failed to make a prima facie case of gender
    
    discrimination. 16
    
          16
            Ms. Miller’s additional contentions regarding her alleged adverse
    treatment also fail. She asserts her starting pay in 1996 was less than that paid to
    men who joined the PGA department between 1998 and 2000. While this is true,
    none of the men during this time ever had hourly wages that surpassed Ms.
    Miller’s. Second, she points to one instance in which a male employee in the
    PGA department received an employment evaluation and raise in 2000, while she
    did not. However, the record indicates Ms. Yager’s decision not to engage in an
    employee evaluation with Ms. Miller in 2000 was in response, in part, to Ms.
    Miller’s own protest that such an evaluation would be unfair in light of the
                                                                           (continued...)
    
                                            -31-
          In order to so conclude, we must return to the thorny discovery question
    
    intertwined with Ms. Miller’s summary judgment challenges. This requires us to
    
    detail some of the earliest stages of Ms. Miller’s litigation against AAA New
    
    Mexico.
    
          The majority of the pre-trial proceedings in Ms. Miller’s action were
    
    conducted before a magistrate judge. During the course of discovery, a dispute
    
    arose between Ms. Miller and AAA New Mexico. On November 15, 2002, Ms.
    
    Miller filed a Combined Motion to Compel Answers to Interrogatories and
    
    Production of Documents and Motion for Sanctions against the company. On
    
    December 2, AAA New Mexico filed its response. It asserted that Ms. Miller’s
    
    requests for discovery had been overly broad, and that it had long since objected
    
    to them. The company noted that five and a half months after it had objected to
    
    her discovery requests, on October 31, 2002, Ms. Miller sent a letter to AAA New
    
    Mexico outlining her specific disagreement with the company’s discovery
    
    objections and demanding a response in five days. By that point in time, the
    
    discovery cutoff date of October 25, 2002 had passed and the magistrate judge
    
    had denied a motion to extend discovery. The company had advised Ms. Miller
    
          16
             (...continued)
    outstanding questions regarding her proper job classification and duties. Finally,
    Ms. Miller makes vague reference to an equally vague notation found in Ms.
    Yager’s notes regarding the job evaluation process stating, “sex change.” App.,
    vol. II at 311. None of these things are sufficient to establish a prima facie case
    of gender discrimination.
    
                                            -32-
    that it intended to respond but could not do so in the stated time frame. It pointed
    
    out that it had responded to Ms. Miller’s letter on November 20, attempting to
    
    narrow or resolve the discovery disputes, but Ms. Miller had not replied to the
    
    letter. Given these circumstances, AAA New Mexico objected to Ms. Miller’s
    
    motion to compel and for sanctions as untimely. It then reiterated some of its
    
    prior objections regarding the breadth of Ms. Miller’s requests and also offered to
    
    produce some additional documents. In her Reply, Ms. Miller agreed to some of
    
    AAA New Mexico’s requested limitations regarding the breadth of a few of her
    
    requests but also continued to make certain objections to the company’s refusal to
    
    produce some information.
    
          On December 23, 2002, prior to entry of any decision on Ms. Miller’s
    
    motion to compel and for sanctions, AAA New Mexico moved for summary
    
    judgment. Ms. Miller filed an additional motion for sanctions on December 26.
    
    On January 21, 2003, the magistrate judge denied as untimely Ms. Miller’s motion
    
    to compel and for sanctions, as well as her second motion for sanctions. The
    
    court cited Local Rule 26.6, which requires a party to file a motion to compel
    
    within twenty calendar days after a response. That “[r]ule states that ‘failure to
    
    proceed within this time period constitutes acceptance of the objection.’” App.,
    
    vol. II at 217. The magistrate judge also denied the motions for sanctions as
    
    untimely, pointing out the discovery cutoff date of October 25, 2002. Id.
    
    
    
                                            -33-
          On January 30, 2003, Ms. Miller filed a motion with the district court
    
    pursuant to F ED . R. C IV . P. 72(a) objecting to the magistrate judge’s denial of her
    
    motion to compel. The next day, she filed her brief in response to the company’s
    
    motion for summary judgment. That document included the following language:
    
          Ms. Miller has a motion to compel pending which seeks additional
          discovery responses, including the personnel files of the males [sic]
          traffic reporters and the public affairs specialist, which could create
          additional factual support for [t]his Response if granted. Ms. Miller
          requests supplemental briefing of these issues if her motion to
          compel is granted.
    
    Id. at 248. Throughout the rest of her summary judgment response, however, Ms.
    
    Miller never explicitly stated what additional evidence she needed from AAA
    
    New Mexico in order to sufficiently challenge its request for summary judgment.
    
          In February, AAA New Mexico responded to Ms. Miller’s objection to the
    
    magistrate judge’s ruling on her motion to compel and for sanctions, disputing her
    
    claims that she had acted diligently in seeking additional discovery from the
    
    company on an informal basis. Ms. Miller filed a reply. The record does not
    
    reflect anything further regarding this matter until June 24, 2003, when the court
    
    filed the final pre-trial order. The pre-trial order contained a section asking
    
    whether there existed any discovery matters of which the court should be aware.
    
    In response, the following appeared: “Yes, Plaintiff objects to the Magistrate’s
    
    denial of her motion to compel and motion for sanctions . . . . The additional
    
    discovery Plaintiff seeks relates primarily to comparable and similarly situated
    
                                              -34-
    employees.” Id. at 414.
    
          In a telephonic hearing on July 11, 2003, the district court addressed what
    
    it described as Ms. Miller’s Motion for Discovery Sanctions. The court stated it
    
    had “considered the materials submitted in support and opposition” to the motion.
    
    Aple. App. at 6. It then focused on AAA New Mexico’s belated production of
    
    two memorandums from Ms. Yager, which it characterized as “extremely relevant
    
    to the issue of breach implied employment contract.” Id. at 7. Concluding that
    
    AAA New Mexico did not intentionally delay in producing the Yager
    
    memorandums, the court declined to grant monetary sanctions but did order the
    
    company to produce Ms. Yager for a supplemental deposition.
    
          During the hearing, the court also indicated to the parties it was planning to
    
    grant summary judgment on the sex discrimination, retaliation, and EPA claims.
    
    At one point, the court addressed the parties and stated, “[i]f there are any
    
    discovery disputes, I do not want those matters to fester . . . . So do you have any
    
    questions of me?” Id. at 9. Ms. Miller’s attorney did not mention the motion to
    
    compel nor did she object to the court’s verbal indication of its intention to grant
    
    summary judgment to AAA New Mexico on the basis that she needed further
    
    discovery. On July 28, the district court issued its partial summary judgment
    
    ruling in favor of the company.
    
          On appeal, Ms. Miller requests that in light of the district court’s failure to
    
    
    
                                             -35-
    respond to her Rule 72(a) objection, we reverse the magistrate judge’s denial of
    
    her motion to compel. For the following reasons, we decline to do so.
    
          Pursuant to 28 U.S.C. § 636(b)(1)(A), magistrate judges have the authority
    
    to enter discovery rulings. See Hutchinson v. Pfeil, 105 F.3d 562, 566 (10th Cir.
    
    1997). “Review of the magistrate judge’s ruling is required by the district court
    
    when a party timely files written objections to that ruling, and the district court
    
    must defer to the magistrate judge’s ruling unless it is clearly erroneous or
    
    contrary to law.” Id. Ms. Miller timely objected to the magistrate judge’s
    
    discovery ruling, but there is no indication the district court explicitly ruled on
    
    her objections to the denial of her motion to compel. Nonetheless, we may
    
    properly construe a district court’s failure to address arguments raised in a Rule
    
    72(a) objection “as an implicit denial of those arguments” and a refusal to
    
    overrule the magistrate judge’s order. Hill v. SmithKline Beecham Corp., 393
    
    F.3d 1111, 1116 (10th Cir. 2004); see also Alpine View Co. v. Atlas Copco AB,
    
    205 F.3d 208, 219-20 (5th Cir. 2000). Based on our review of the record, we are
    
    convinced the district court implicitly denied Ms. Miller’s Rule 72(a) challenge.
    
          During the course of the district court’s telephonic hearing on Ms. Miller’s
    
    sanction requests, the court stated it had reviewed all the materials in support of
    
    and opposition to her requests for sanctions. The record indicates Ms. Miller’s
    
    initial motion for sanctions was combined with her motion to compel. The parties
    
    
    
                                              -36-
    engaged in significant briefing in regard to this initial motion, as well in response
    
    to Ms. Miller’s additional sanctions request. The magistrate judge’s ruling
    
    addressed both of Ms. Miller’s requests for sanctions as well as her motion to
    
    compel. In her Rule 72(a) objection to this ruling, Ms. Miller challenged the
    
    denial of both her motion to compel and her motions for sanctions. She also
    
    mentioned her pending motion to compel in her response to AAA New Mexico’s
    
    motion for summary judgment, albeit in a very general manner. Likewise, the
    
    pre-trial order indicates Ms. Miller again raised her outstanding discovery issues.
    
    Taken together, we are convinced the district court was duly apprised of the scope
    
    of Ms. Miller’s arguments relating to both her motion to compel and her motion
    
    for sanctions. Given the court’s denial of her motion for sanctions in conjunction
    
    with its subsequent order granting AAA New Mexico summary judgment on a
    
    number of the claims implicated by her discovery requests, we conclude the
    
    district court’s silence on Ms. Miller’s motion to compel was a conscious and
    
    implicit denial of her discovery requests and a refusal to overrule the magistrate
    
    judge’s order. See Hill, 393 F.3d at 1116; Alpine View Co., 205 F.3d at 219-20.
    
          On appeal, Ms. Miller asks that we reverse the magistrate judge’s ruling.
    
    In light of our conclusion that the district court implicitly rejected her motion to
    
    compel, it is more appropriate for us to determine whether the district court
    
    abused its discretion in so doing. See Cummings v. Gen. Motors Corp., 365 F.3d
    
    
    
                                             -37-
    944, 952-53 (10th Cir. 2004) (citing Motley v. Marathon Oil Co., 71 F.3d 1547,
    
    1550 (10th Cir. 1995)) (court of appeals will not set aside district court discovery
    
    rulings absent abuse of discretion). In this regard, “[s]uch an abuse will occur
    
    only when the judge renders ‘an arbitrary, capricious, whimsical, or manifestly
    
    unreasonable’ judgment.” Id. at 953 (quoting Coletti v. Cudd Pressure Control,
    
    165 F.3d 767, 777 (10th Cir. 1999) (further internal quotations and citations
    
    omitted)). 17
    
    
            We also note that if Ms. Miller’s true goal in challenging the denial of her
           17
    
    motion to compel was to reopen discovery so as to garner additional evidence
    before the district court’s summary judgment ruling, she should have filed an
    affidavit pursuant to F ED . R. C IV . P. 56(f) seeking a continuance and explaining
    why she could not currently present facts to justify her opposition to the
    company’s motion. Ms. Miller concedes she did not file such an affidavit. Aplt.
    Reply Br. at 26. Her failure to do so further undermines her challenge to the
    magistrate judge’s discovery order, as well as her challenge to the district court’s
    grant of summary judgment to AAA New Mexico.
           Ms. Miller nonetheless argues that taken as a whole, her discovery
    pleadings, the statement regarding the pending motion to compel in her response
    to AAA New Mexico’s motion for summary judgment, and her Rule 72(a)
    objection are sufficient to satisfy Rule 56(f). We do not agree. Rule 56(f) “may
    not be invoked by the mere assertion that discovery is incomplete or that specific
    facts necessary to oppose summary judgment are unavailable.” Pasternak v. Lear
    Petroleum Exploration, Inc., 790 F.2d 828, 833 (10th Cir. 1986). Moreover,
    unverified statements in attorney memoranda, including a response opposing
    summary judgment, are not sufficient for a Rule 56(f) continuance. Comm. for
    the First Amendment v. Campbell, 962 F.2d 1517, 1522 (10th Cir. 1992). Ms.
    Miller’s other attempts to halt the district court’s summary judgment ruling are
    insufficient to square with our precedents.
           We have held that “[w]here a party opposing summary judgment and
    seeking a continuance pending completion of discovery fails to take advantage of
    the shelter provided by Rule 56(f) by filing an affidavit, there is no abuse of
    discretion [by the district court] in granting summary judgment if it is otherwise
                                                                              (continued...)
    
                                             -38-
          We conclude the district court did not abuse its discretion in implicitly
    
    denying Ms. Miller’s Rule 72(a) objection. As discussed above, the court had
    
    before it all of the arguments and materials it needed to make this determination.
    
    Included within these materials was Ms. Miller’s response to AAA New Mexico’s
    
    motion for summary judgment, in which she included only a very limited
    
    statement indicating that the personnel files of the other male traffic reporters in
    
    the PGA department as well as the personnel file for Mr. Ware, the man who held
    
    the new job, might “create additional factual support” for her summary judgment
    
    response. App., vol. II at 248. The statement in the pre-trial order was similarly
    
    limited. See id. at 414. Ms. Miller provided no details in these materials
    
    regarding how her opposition to AAA New Mexico’s motion for summary
    
    judgment was undermined by the lack of additional discovery, nor did she file an
    
    affidavit pursuant to F ED . R. C IV . P. 56(f). Under these circumstances, we cannot
    
    say the district court’s implicit rejection of Ms. Miller’s motion was “arbitrary,
    
    capricious, whimsical, or manifestly unreasonable.” Cummings, 365 F.3d at 953.

    appropriate.” Pasternak, 790 F.2d at 832-33; see also Weir v. Anaconda Co., 773
    F.2d 1073, 1082 n.10 (10th Cir. 1985) (listing cases). Hence, even if we were to
    determine the district court did not implicitly deny Ms. Miller’s Rule 72(a)
    motion to compel in the course of making its sanctions ruling and granting
    summary judgment to AAA New Mexico, Ms. Miller’s failure to comply with
    Rule 56(f) would also undermine her challenge on appeal.

          B. EPA claim
    
          Ms. Miller contended AAA New Mexico violated the EPA because it paid
    
    her a lower wage than members of the opposite sex doing equal work. To make a
    
    prima facie case under the EPA, Ms. Miller
    
          has the burden of proving that (1) she was performing work which
          was substantially equal to that of the male employees considering the
          skills, duties, supervision, effort and responsibilities of the jobs; (2)
          the conditions where the work was performed were basically the
          same; (3) the male employees were paid more under such
          circumstances.
    
    Sprague, 129 F.3d at 1364 (quoting Tidwell v. Fort Howard Corp., 989 F.2d 406,
    
    409 (10th Cir. 1993) (further citations omitted)). We agree with the district
    
    court’s determination that Ms. Miller failed to make out a prima facie case.
    
          Ms. Miller’s EPA claims mirrored her Title VII claims. She asserted the
    
    men in the PGA department were better compensated than she, and that Mr. Ware
    
    was paid more than she was for a substantially similar position. As we discussed
    
    above, the evidence indicates Ms. Miller was paid a higher hourly wage than all
    
    the men in her department. Her comparison of her work with Mr. Ware’s job is
    
    equally faulty.
    
          When addressing the “equal work” requirement of the EPA, we do not
    
    construe it broadly. “[W]e have stated that failure to furnish equal pay for
    
    ‘comparable work’ or ‘like jobs’ is not actionable.” Id. (citations omitted).
    
    Instead, “in order to prevail in such an EPA action, the jobs must be substantially
    
                                            -40-
    equal in terms of skill, effort, responsibility, and working conditions.” Id.
    
    (internal quotations and citation omitted). Again, much like the employee in
    
    Sprague who performed some but not all of the duties of higher paid male
    
    employees, id. at 1364-65, the same can be said of Ms. Miller. As we have
    
    thoroughly discussed, the record makes clear that while Ms. Miller did perform
    
    some of the duties that were included in the newly created post, she did not
    
    perform all of those duties. She simply has not made a prima facie case that the
    
    jobs were substantially similar. As with the Title VII claim addressed above, we
    
    conclude the district court did not err in its summary judgment ruling, or abuse its
    
    discretion in impliedly rejecting Ms. Miller’s Rule 72(a) motion.
    
    
    
          C. Retaliation claim
    
          Finally, Ms. Miller claimed AAA New Mexico retaliated against her by
    
    eliminating her hourly position and forcing her to apply for the new post after she
    
    had complained of sex discrimination. In order to state a prima facie case of
    
    retaliation, a plaintiff must demonstrate that (1) she was engaged in protected
    
    opposition to discrimination; (2) she suffered an adverse employment action; and
    
    (3) a causal connection existed between the protected activity and the adverse
    
    employment action. Duncan v. Manager, Dep’t of Safety, City & County of
    
    Denver, 397 F.3d 1300, 1314 (10th Cir. 2005); Stover v. Martinez, 382 F.3d 1064,
    
    
    
                                             -41-
    1070-71 (10th Cir. 2004); see also Shovelin v. Central N.M. Elec. Co-op, Inc.,
    
    850 P.2d 996, 1006 (N.M. 1993) (setting out New Mexico state law requirements
    
    for retaliatory discharge claim). Once a plaintiff establishes her prima facie case,
    
    the burden shifts to the employer to offer a facially legitimate rationale for the
    
    adverse action. The burden then shifts back to the plaintiff to show the
    
    employer’s explanation is pretext. Stover, 382 F.3d at 1071. The district court
    
    determined that Ms. Miller failed to make her prima facie case because there was
    
    not a sufficient causal connection between her complaints of discrimination and
    
    the elimination of her position and application requirement for the new post. The
    
    court also held Ms. Miller had failed to show the company’s decision to perform a
    
    job study, create two new regular positions, and eliminate her hourly part-time
    
    position, was pretextual. We agree.
    
          We find no real contest regarding Ms. Miller’s assertions that she satisfied
    
    the first two prongs of the prima facie analysis for retaliation claims. The record
    
    indicates that in early November 1999, during a meeting with Ms. Yager, Ms.
    
    Miller first stated she “thought the company was not treating her equitably . . . it
    
    wasn’t fair . . . [and] was discriminatory.” App., vol. II at 289. Lodging a
    
    discrimination complaint is protected activity for retaliation claim purposes. See
    
    O’Neal v. Ferguson Constr. Co., 237 F.3d 1248, 1255 (10th Cir. 2001); Archuleta
    
    v. Colo. Dep’t of Insts., Div. of Youth Servs., 936 F.2d 483, 486 (10th Cir. 1991);
    
    
    
                                             -42-
    Martinez v. City of Grants, 927 P.2d 1045, 1053 (N.M. 1996). Likewise, the
    
    elimination of Ms. Miller’s hourly position, along with the company’s failure to
    
    promote her as allegedly promised, constitute adverse employment actions.
    
    Burlington Indus., Inc. v. Ellerth, 524 U.S. 742, 761 (1998) (“A tangible
    
    employment action constitutes a significant change in employment status, such as
    
    hiring, firing, failing to promote, reassignment with significantly different
    
    responsibilities, or a decision causing a significant change in benefits.”); Duncan,
    
    397 F.3d at 1314 (“An adverse employment action must be materially adverse to
    
    the employee’s job status. The adverse action must amount to a significant
    
    change in employment status, such as firing, failing to promote, reassignment
    
    with significantly different responsibilities, or a decision causing a significant
    
    change in benefits.”) (quotation omitted). 18
    
          The evidence also indicates that soon after Ms. Miller stated she believed
    
    
          18
             We note that generally, “[i]n order for a plaintiff to assert that her
    employer retaliated against her by failing to hire, rehire, or promote her, that
    employee must have applied for the position she was denied.” Stover v. Martinez,
    382 F.3d 1064, 1072 (10th Cir. 2004). Here, Ms. Miller did not apply for the new
    position. But at this point in our analysis, we are not entirely convinced this fact
    wholly undermines her retaliation claim. Even if Ms. Miller could not assert that
    AAA New Mexico’s failure to promote her was an adverse employment action,
    her hourly position was terminated. Moreover, her retaliation allegations appear
    to go hand in hand, rather than to be mutually exclusive. It was the final action of
    AAA New Mexico in restructuring the PGA department, in which Ms. Miller’s
    current hourly position was eliminated and she was required to apply for the new
    job which supposedly had the same duties as her former post, that was the alleged
    retaliatory act committed by AAA New Mexico.
    
                                             -43-
    she was being treated in a discriminatory fashion, Ms. Yager and Ms. Bisno met,
    
    on November 17, 1999, to begin discussing how the PGA department might be
    
    reorganized to include two new full-time regular positions. During the course of
    
    these meetings and into January 2000, it was decided that Ms. Miller’s hourly
    
    position would be eliminated, and she would have to apply for the newly created
    
    position pursuant to AAA New Mexico policy. This decision was announced to
    
    Ms. Miller in early February 2000, three months after her first articulated
    
    allegations of discrimination. It was not until after Ms. Miller decided not to
    
    apply for the new position and it was determined her last day at AAA New
    
    Mexico would be May 5, 2000, however, that her hourly position was eliminated.
    
          The district court determined Ms. Miller failed to show a causal connection
    
    between her complaints of discrimination and the adverse employment actions she
    
    suffered. We agree, although on a slightly different timeline. The district court
    
    reasoned Ms. Miller began to complain of adverse treatment in March 1998, but it
    
    was not until May of 2000, nearly two years after her initial allegations of unfair
    
    treatment, that Ms. Miller’s position was eliminated. On these grounds, the court
    
    determined that a sufficient temporal proximity was lacking between Ms. Miller’s
    
    allegations of unfair treatment and her job termination. We draw a more narrow
    
    time frame.
    
          Ms. Miller certainly expressed discontent from at least March 1998, and
    
    
    
                                            -44-
    throughout her employment at AAA New Mexico, regarding her compensation,
    
    job title, and work duties. But it was not until early November 1999 that she
    
    made any specific allegations regarding being treated in an unfavorable manner
    
    because of her sex. Within that same month, Ms. Yager and Ms. Bisno initiated a
    
    series of meetings to discuss how to restructure the PGA department and
    
    eventually settled on the elimination of Ms. Miller’s hourly position and the
    
    creation of a new post for which she could apply. Ms. Miller was informed of
    
    these facts in February 2000, and in May of that year her hourly position was
    
    eliminated at the conclusion of her employment with AAA New Mexico. Hence,
    
    instead of a two year window of time between Ms. Miller’s general complaints
    
    about her treatment and her departure from the organization, as found by the
    
    district court, there exists a six month window between Ms. Miller’s allegations
    
    of discrimination based on her sex and the elimination of her post. Even within
    
    this more narrowly circumscribed timeline, however, Ms. Miller failed to satisfy
    
    the causal connection prong of her prima facie case.
    
          We have held “[t]he causal connection may be demonstrated by evidence of
    
    circumstances that justify an inference of retaliatory motive, such as protected
    
    conduct closely followed by adverse action.” Burrus v. United Tel. Co. of Kan.,
    
    Inc., 683 F.2d 339, 343 (10th Cir. 1982). However, “unless the [adverse action]
    
    is very closely connected in time to the protected activity, the plaintiff must rely
    
    
    
                                             -45-
    on additional evidence beyond mere temporal proximity to establish causation.”
    
    Meiners v. Univ. of Kan., 359 F.3d 1222, 1231 (10th Cir. 2004) (citing Anderson
    
    v. Coors Brewing Co., 181 F.3d 1171, 1179 (10th Cir. 1999)). In Meiners, we
    
    determined that a “six-week period between protected activity and adverse action
    
    may be sufficient, standing alone, to show causation, but a three-month period,
    
    standing alone, is insufficient.” Id. Here there exists a six month window
    
    between Ms. Miller’s allegations of sexual discrimination and the elimination of
    
    her hourly position. This alone is insufficient to establish a prima facie case, and
    
    Ms. Miller does not point to much other evidence to support her cause.
    
          Ms. Miller generally argues that the slow progress of the job review process
    
    led her to “suspect that something unlawful accounted for the delay.” Aplt. Br. at
    
    39. That seeming unlawfulness was connected to Ms. Miller’s perception that she
    
    was being compensated less favorably than the men in her department. But her
    
    own suppositions regarding the delay in the job review process are not sufficient
    
    to establish a prima facie case of retaliation. Cf. Amro v. Boeing Co., 232 F.3d
    
    790, 798 & n.6 (10th Cir. 2000) (employee’s own perceptions of lack of fair
    
    treatment insufficient to state Title VII claim); Kelley v. Goodyear Tire & Rubber
    
    Co., 220 F.3d 1174, 1177 (10th Cir. 2000) (“A plaintiff cannot create a triable
    
    issue of fact by making an assertion without supporting facts.”); Jones v. Denver
    
    Post Corp., 203 F.3d 748, 753-54 (10th Cir. 2000) (manager’s perception of
    
    
    
                                             -46-
    employee performance is relevant for demotion claim, not employee’s own
    
    evaluation of performance). She also argues that AAA New Mexico effectively
    
    “scrapped its promise” to upgrade her and “then set about finding a way to get rid
    
    of [her] . . . without it looking illegal.” Aplt. Br. at 40. A review of the record
    
    negates this argument.
    
          Long before Ms. Miller raised her concerns regarding discrimination, Ms.
    
    Yager had been advocating for changes in the PGA department. In particular, and
    
    in large measure due to Ms. Miller’s inquiry as to whether she was being
    
    appropriately compensated for her work, Ms. Yager sought to obtain two regular
    
    employees in her department to perform public affairs duties, rather than having
    
    the work done by part-time hourly employees. During a series of depositions, Ms.
    
    Yager was repeatedly questioned regarding the process of deciding to eliminate
    
    Ms. Miller’s hourly position and to create a new post in its place. Ms. Yager
    
    consistently testified that
    
          [t]here wasn’t a conscious decision to eliminate positions. It was
          looked at what the business needs of the operation were and we
          decided that those two part-time positions were not serving the needs
          of the department and that we needed two full-time positions. And it
          was my understanding that that’s what the two employees were
          requesting as well.
    
    App., vol. I at 156. When asked the same question later, Ms. Yager responded:
    
    “I don’t think my answer is any different to that question. We had two hourly
    
    positions which . . . were not meeting the needs of the department, and so when
    
                                             -47-
    we looked at all the information, we knew that full-time positions were needed.”
    
    Id. When questioned yet again as to why she did not just seek to upgrade the
    
    positions rather than create two new posts, she stated
    
           I don’t see that as a separate entity. When we looked at the tasks that
           were currently being done and the tasks that needed to be done, and
           we knew that the part-time hours were not enough, we knew that the
           employees were upset by being in part-time positions, we looked to
           see what would serve the needs of the department to the best of our
           ability.
    
     Id. at 209. 19
    
           Ms. Bisno was posed with a similar series of questions, and responded in
    
    kind. She stated that the decision to eliminate the two hourly positions was made
    
           at the time that we were evaluating what we needed to do for public
           affairs in AAA New Mexico, what kinds of positions we needed.
           And since the determination was that we needed – we wanted two
           full-time positions rather than two part-time hourly positions, that’s
           when the discussion was started . . . . [T]he plan when we started
           developing [it] was that we were not [going to] have hourly
           positions, we were [going to] have full-time positions.
    
    Id., vol. II at 326. When pressed as to why they eliminated the hourly jobs rather
    
    than reclassifying their status from hourly to regular, she stated
    
    
    
            While Ms. Yager may have expressed a desire and intent to have Ms.
           19
    
    Miller serve in the regular position once it was created, the record indicates that it
    was “company policy that any new position in the company needed to be posted,
    and that [Ms. Miller] would have to apply for the position[].” App., vol. II at
    299. When Ms. Yager learned of this fact, she knew Ms. Miller would be
    disappointed and upset, but Ms. Yager “thought it was just a matter of policy so
    [she] didn’t think it was an unfair or unreasonable request to make.” Id. at 300.
    
    
                                             -48-
          [b]ecause . . . aside from the hours, the positions were different. We
          looked at not only what we were doing, but what we needed to do,
          where we had to be in the future, and what the responsibilities of the
          positions ought to be. And they were not the same as we had under
          the current arrangement. So they were different enough. And
          constantly in conversation with our hierarchy, with Human
          Resources, the decision was, we would eliminate the old, create the
          new.
    
    Id. at 326-27. She further commented that “if [a] position changes sufficiently,
    
    you essentially eliminate the old group of positions and you create new
    
    positions.” Id. at 327. When pressed by counsel as to why the hourly positions
    
    were not merely reclassified as regular, she again emphasized that the
    
          existing position as defined by the duties that were being done was
          not deemed to be the one that we needed for Public Affairs and AAA
          New Mexico, that we needed different responsibilities . . . . My
          understanding of a reclassification is when you look at the existing
          position and you evaluate the existing position and decide, for
          whatever reason, whether internal or external, that you need to
          change where you have that. The whole position gets moved. But
          the position itself doesn’t change. The job duties don’t change. The
          qualifications needed don’t change.
    
    Id. at 329 (emphasis added). Ms. Miller has pointed to nothing contrary in the
    
    record except her own assertions that she was entitled to be placed in the new
    
    position. We thus conclude she has failed to “provide evidence other than
    
    temporal proximity to establish a prima facie case.” Meiners, 359 F.3d at 1231.
    
          We also agree with the district court’s ruling on pretext. Ms. Miller’s
    
    pretext argument seems to dovetail with her prima facie position regarding AAA
    
    New Mexico’s elimination of her hourly post and creation of the regular position.
    
                                            -49-
    A grant of summary judgment is appropriate where a plaintiff cannot meet the
    
    burden of proving that an employer’s articulated nondiscriminatory reason for an
    
    alleged retaliatory action is pretextual. Kelley, 220 F.3d at 1174. “An employee
    
    may demonstrate pretext by showing the employer’s proffered reason was so
    
    inconsistent, implausible, incoherent, or contradictory that it is unworthy of
    
    belief.” Stover, 382 F.3d at 1071 (citing Bausman v. Interstate Brands Corp., 252
    
    F.3d 1111, 1120 (10th Cir. 2001)). Ms. Miller has failed to do so here.
    
          In an attempt to show AAA New Mexico’s elimination of her position and
    
    creation of the new post were pretext for dismissing her for her complaints of
    
    discrimination, Ms. Miller cites to Butler v. City of Prairie Vill., 172 F.3d 736
    
    (10th Cir. 1999). While Butler does present some initial similarities to Ms.
    
    Miller’s case, we are not persuaded it supports her pretext argument.
    
          In Butler, an employee brought a retaliation claim under the Americans
    
    with Disabilities Act (ADA), asserting he was terminated as a result of his
    
    requests for accommodations under the ADA. Id. at 751-52. In response, his
    
    employer maintained his position was eliminated as a result of the reorganization
    
    of the department in which he worked. On appeal, we held that genuine issues of
    
    material fact existed as to whether the employer’s proffered reason for
    
    terminating the plaintiff was pretextual. We noted most of the plaintiff’s former
    
    job duties were resurrected in a new position nine months after the departmental
    
    
    
                                             -50-
    reorganization and his termination. Moreover, after he had requested an
    
    accommodation, “he received more work than he could successfully complete and
    
    his supervisors complained about having too much work because they had to
    
    cover for him.” Id. at 752. Finally, his position was the only one to be eliminated
    
    while it was occupied. Id. We also pointed to the temporal proximity of other
    
    events during the plaintiff’s employment which supported his pretext argument.
    
    For example, the employer’s “decision to reorganize [the department] occurred
    
    within weeks of Plaintiff’s delivery of a complaint” to the mayor about his
    
    supervisor, id., and his work evaluations “declined sharply within the months
    
    after” he informed his employers of his disability and need for accommodations.
    
    Id. We also commented that the duties of the new position appeared to
    
    substantially overlap the duties the plaintiff had previously held. Id. at 750.
    
    These facts together created genuine issues of material fact regarding whether the
    
    employer’s reasons for terminating the plaintiff were pretextual.
    
          Ms. Miller claims her case is sufficiently analogous to Butler to warrant a
    
    reversal of the district court’s grant of summary judgment to AAA New Mexico
    
    on her retaliation claim. We disagree. First, in contrast to Butler, Ms. Yager
    
    instigated the job study and departmental reevaluation process long before Ms.
    
    Miller ever alleged she was being discriminated against because of her sex. As
    
    we have already stated, Ms. Yager’s initiation of this process was driven in large
    
    
    
                                             -51-
    measure by Ms. Miller’s own questions as to whether she was appropriately
    
    classified and paid for the work she was performing. Moreover, Ms. Yager, as
    
    well as Ms. Bisno, testified it was always their understanding that as a result of
    
    the job study, there would no longer be two hourly part-time positions in the PGA
    
    department, but instead the department would have two full-time hourly positions.
    
    While the review of the department’s needs and the final creation of the two new
    
    positions did not occur until after Ms. Miller raised her claims of discrimination,
    
    we do not think this temporal proximity is sufficient to undermine the record
    
    presented by AAA New Mexico that it had been involved in the job evaluation
    
    process for some time, and that the decision to create two regular positions in lieu
    
    of the hourly posts was anything other than a legitimate business decision. 20
    
          20
             We are also not convinced by Ms. Miller’s argument that failure to
    exempt her from AAA New Mexico’s requirement that the new jobs be posted
    was evidence of pretext. AAA New Mexico’s posting policy indicates that “[a]ll
    positions are listed in the job vacancy bulletin, ‘Opportunity Knocks.’ Exceptions
    may be made to: Consider [an] employee returning from a family, pregnancy or
    illness/injury leave of absence, if qualified for a job guarantee. Consider an
    employee whose position is being phased out through the Staff Reduction
    Program.” Id. at 389. Ms. Miller makes no convincing argument as to how she
    would be exempted under the policy.
           We further disagree that the close timing of Ms. Matthewson’s termination
    in relation to the events in this case is additional evidence of pretext. Ms.
    Matthewson, who is not a party in this litigation, was fired within a month of the
    February 2000 meeting for insubordination and for creating a hostile work
    environment. But Ms. Miller poses no challenge to the articulated reasons given
    by AAA New Mexico for her mother’s termination. Rather, she merely contends
    that the close proximity of her mother’s firing with her own allegations of
    discrimination creates pretext as to AAA New Mexico’s decision to eliminate Ms.
                                                                             (continued...)
    
                                             -52-
          Second, Ms. Miller argues that similar to the employer in Butler, AAA New
    
    Mexico eliminated her position but then created a new position with substantially
    
    the same job duties. We have already rejected this similar argument in the
    
    context of Ms. Miller’s Title VII and EPA claims, and do so again here. The new
    
    job held by Dan Ware was not merely a refashioning of the work previously
    
    performed by Ms. Miller. Rather, it represented a significant refocus in job duties
    
    as well as additional duties that Ms. Miller had not performed in her hourly post.
    
          Ms. Miller also contends Ms. Bisno’s statement that she did not intend to
    
    respond to Ms. Miller’s concerns regarding discrimination is additional evidence
    
    of pretext. We are not convinced. Nothing in the follow-up memorandum Ms.
    
    Miller and her mother sent to Ms. Bisno after the February 2000 meeting
    
    indicated they had any workplace discrimination concerns. Nor has Ms. Miller
    
    presented anything to undermine Ms. Bisno’s statements that it was not until after
    
    Ms. Miller quit working for the company that Ms. Bisno became aware her claims
    
    of discrimination were based on “some protected basis.” App., vol. II at 322,
    
    327. Hence, Ms. Miller has presented nothing to indicate Ms. Bisno’s
    
    
          20
             (...continued)
    Miller’s hourly position and create a new regular position for which she could
    apply. Even if the temporal proximity of her mother’s firing with Ms. Miller’s
    allegations of discrimination might support her initial retaliation charge, Ms.
    Miller has failed to demonstrate pretext by showing AAA New Mexico’s reason
    for firing her mother “was so inconsistent, implausible, incoherent, or
    contradictory that it is unworthy of belief.” Stover, 382 F.3d at 1070-71.
    
                                            -53-
    disinclination to respond to the women’s articulated concerns, none of which
    
    addressed issues of sex discrimination, is further evidence that AAA New Mexico
    
    intended to retaliate against Ms. Miller for her claims of discrimination.
    
          Finally, we reject Ms. Miller’s claim that the process by which the AAA
    
    Texas office treated an employee in a situation somewhat similar to Ms. Miller’s
    
    supports her pretext argument. Ms. Miller asserts that around the same time AAA
    
    New Mexico was engaged in the job study for the new position, the AAA office
    
    in Texas was engaged in a similar process. The Texas organization was in the
    
    final stages of receiving approval to fill a newly created Public Affairs Specialist
    
    position and in the mean time, was given permission by human resources to
    
    employ a woman named Rose Rougeau as a part-time temporary hourly employee.
    
    Ms. Rougeau was to perform the duties of the soon to be finalized position. Once
    
    final approval for the position was received, the Texas office had permission to
    
    migrate Ms. Rougeau from the temporary hourly position into the regular post.
    
    Ms. Bisno, who was involved in this process, testified that “when we arranged the
    
    temporary hours, it was with the understanding that if the relationship worked out
    
    satisfactorily when the position was created, that [Ms. Rougeau] would be moved
    
    into it.” Id. at 325. She also stated Ms. Rougeau and the Texas office “knew
    
    what duties she was hired to perform, but [Ms. Rougeau] was aware that at the
    
    time we did not have a position to offer her.” Id. at 324. Ms. Rougeau did not
    
    
    
                                            -54-
    oppose the terms of this arrangement, and after working on a temporary hourly
    
    part-time basis for about four months, and upon the finalization of the regular
    
    Public Affairs Specialist position, she moved into that job without having to apply
    
    for it.
    
              Based on the events which occurred in the Texas AAA office, Ms. Miller
    
    contends AAA had a policy of automatically transferring hourly employees into
    
    regular positions and should have done the same for her. She argues the
    
    company’s failure to do so is further evidence of pretext. While the two
    
    situations do bear a measure of similarity, we are not convinced the facts
    
    surrounding Ms. Rougeau’s job advancement are sufficiently analogous to Ms.
    
    Miller’s case to support her argument. In contrast to Ms. Rougeau’s situation,
    
    when Ms. Miller began working for AAA New Mexico, she began as an hourly
    
    employee and continued to do so throughout her tenure for the company. Nor was
    
    any promise made to Ms. Miller in the hiring process that a regular position was
    
    on the verge of creation and immediately available for her to fill if she was
    
    interested. Furthermore, unlike Ms. Rougeau, who was specifically hired to
    
    perform the duties of a Public Affairs Specialist, despite the salaried position not
    
    being quite yet finalized, Ms. Miller was hired to perform traffic reporting duties
    
    within an established clerk position. It was only later during her time at the
    
    company that Ms. Miller agreed to take on additional public affairs duties.
    
    
    
                                              -55-
    Therefore, the facts surrounding Ms. Rougeau’s advancement are inapposite to
    
    Ms. Miller’s situation and insufficient to support her claims of pretext.
    
          In conclusion, Ms. Miller has made numerous broad assertions in an
    
    attempt to show that AAA New Mexico’s decision to eliminate her hourly
    
    position and create a new post for which she was required to apply was pretext for
    
    its alleged retaliation against her for making a discrimination claim. Viewing
    
    these assertions as whole, we agree with the district court that Ms. Miller has
    
    failed to show that the specific manner in which AAA decided to reorganize the
    
    PGA department was pretext for releasing her.
    
          Nor are we persuaded the district court abused its discretion in implicitly
    
    rejecting Ms. Miller’s Rule 72(a) motion regarding this claim. In the assorted
    
    material before the district court, Ms. Miller asserted generally that she needed a
    
    variety of additional documents. These included information on how other
    
    complaints of employment discrimination or retaliation were handled by AAA
    
    New Mexico, as well as any documentation regarding her own claims of
    
    discrimination; personnel files regarding other public affairs specialist positions
    
    with the larger AAA organization; any additional documents in Ms. Yager’s
    
    possession regarding Ms. Miller or Ms. Matthewson; and any documents having
    
    to do with Ms. Miller’s job evaluations and the job study process. As noted
    
    earlier, however, Ms. Miller did not highlight in her response to AAA New
    
    
    
                                             -56-
    Mexico’s motion for summary judgment what additional information she was
    
    lacking, and how the presence of such evidence would support her in undermining
    
    AAA New Mexico’s motion for summary judgment on her retaliation claims.
    
    Rather, the single sentence in her summary judgment response seems to speak
    
    more in terms of her Title VII and EPA claims and does not make any direct
    
    reference to her retaliation claims. Ms. Miller’s statement included in the pre-
    
    trial order is similarly silent regarding her retaliation claims. Nor did she file a
    
    Rule 56(f) affidavit. Finally, in her reply brief on appeal, Ms. Miller limits her
    
    discovery argument to her Title VII and EPA claims stating “if remand occurs on
    
    the discrimination or EPA claims, production should too.” Aplt. Reply Br. at 26.
    
    Coupled with our determination that the district court did not err in granting
    
    summary judgment to AAA New Mexico on Ms. Miller’s retaliation claims, we
    
    conclude the district court did not abuse its discretion in implicitly denying her
    
    Rule 72(a) motion.
    
    
    
                                              III
    
          We finally address Ms. Miller’s argument that the district court erred in
    
    granting judgment as a matter of law to AAA New Mexico on her claims for
    
    breach of an implied employment contract and the covenant of good faith and fair
    
    dealing. A close read of the trial record indicates the district court permitted Ms.
    
    
    
                                              -57-
    Miller’s breach of implied contract claim to be presented to the jury on very
    
    narrow grounds. The court construed Ms. Miller’s claim to be that, after
    
    allegedly agreeing to place Ms. Miller in a promoted position and after Ms. Miller
    
    allegedly fulfilled the duties of the new position, AAA New Mexico retroactively
    
    altered the terms of the agreement by failing to place Ms. Miller into the position
    
    once it was finally created. The court concluded such a claim was not barred as a
    
    matter of law, and permitted evidence to be presented to the jury. The jury was to
    
    determine if, in fact, AAA New Mexico had entered into such an agreement with
    
    Ms. Miller, and if so, whether she was entitled to retroactive pay in light of AAA
    
    New Mexico’s failure to comply with the alleged contract.
    
          After each side presented its evidence, the company moved for judgment as
    
    a matter of law. While the district court expressed great skepticism that sufficient
    
    evidence existed to support Ms. Miller’s claim, it nonetheless reserved its ruling
    
    on the company’s motion and referred the matter to the jury. The court declared a
    
    mistrial after the jury was unable to reach an unanimous verdict on Ms. Miller’s
    
    claims. In accordance with F ED . R. C IV . P. 50(b)(2)(B), AAA New Mexico
    
    renewed its motion for judgment as a matter of law. The court subsequently ruled
    
    in the company’s favor, reasoning that Ms. Miller had failed to point to “any
    
    specific and binding promise by AAA,” app., vol. II at 552, that would permit a
    
    jury to determine the company had impliedly contracted with Ms. Miller to
    
    
    
                                            -58-
    upgrade her position, or that she should receive retroactive compensation.
    
          AAA New Mexico presents two alternative arguments in challenging Ms.
    
    Miller’s appeal on this issue. It initially contends that pursuant to the New
    
    Mexico Court of Appeals rulings in Stieber v. Journal Publ’g Co., 901 P.2d 201,
    
    204 (N.M. Ct. App. 1995), and Gormley v. Coca-Cola Enters., 85 P.3d 252, 259
    
    (N.M. Ct. App. 2003), aff’d on other grounds, 109 P.3d 280 (N.M. 2005), Ms.
    
    Miller’s at-will status precludes her implied breach of contract claim as a matter
    
    of law. In the alternative, it contends that even if Ms. Miller was entitled to bring
    
    the contract claim, she failed to present sufficient evidence to permit a jury to
    
    determine that such a contract existed. Ms. Miller’s implied contract claim fails
    
    under either approach. 21
    
    
    
          A. Claim barred as a matter of law
    
          We begin by noting that we need not employ the same analysis relied upon
    
    by the district court. Rather, “we may affirm the judgment of the district court on
    
    any grounds for which there is a record sufficient to permit conclusions of law,
    
    even grounds not relied upon by the district court.” V-1 Oil Co. v. Means, 94
    
          21
             In light of our conclusion that Ms. Miller’s implied breach of contract
    claim fails, we need not decide whether the district court erred in granting
    judgment as a matter of law on her breach of the covenant of good faith and fair
    dealing claim. We likewise need not address her associated challenges to the
    district court’s jury instructions on her breach of contract claim, or its limitations
    on damages available for the same.
    
                                             -59-
    F.3d 1420, 1423 (10th Cir. 1996); see also United States v. Davis, 339 F.3d 1223,
    
    1227 (10th Cir. 2003); Dominion Video Satellite, Inc. v. EchoStar Satellite Corp.,
    
    269 F.3d 1149, 1157 (10th Cir. 2001). Addressing the company’s first argument
    
    against Ms. Miller, we conclude that as a matter of New Mexico law, Ms. Miller’s
    
    implied contract claim against AAA New Mexico was precluded on the basis of
    
    her at-will employment status.
    
          AAA New Mexico contends that Stieber and Gormley wholly control the
    
    disposition of this case and bar any implied contract action by Ms. Miller. While
    
    we inevitably determine the rationale underlying Stieber and Gormley supports
    
    the company’s argument, we are not entirely persuaded these two cases
    
    automatically preclude Ms. Miller’s claims. Stieber and Gormley certainly do
    
    place limits on an at-will employee’s ability to bring certain types of implied
    
    contract claims. However, those two appellate court cases do not definitively
    
    answer the question at issue here: can an at-will employee bring an implied
    
    contract claim for an employer’s failure to fulfill promises to make future changes
    
    to a job?
    
          When assessing the propriety of a district court’s disposition of state law
    
    claims, we have the “duty to apply state law as announced by the state’s highest
    
    court.” Koch v. Koch Indus., Inc., 203 F.3d 1202, 1230 (10th Cir. 2000). Absent
    
    controlling precedent, we “must attempt to predict how the state’s highest court
    
    
    
                                             -60-
    would resolve the issue.” Royal Maccabees Life Ins. Co. v. Choren, 393 F.3d
    
    1175, 1180 (10th Cir. 2005); see also Rancho Lobo, Ltd. v. Devargas, 303 F.3d
    
    1195, 1202 n.2 (10th Cir. 2002); FDIC v. Schuchmann, 235 F.3d 1217, 1225 (10th
    
    Cir. 2000). “In conducting our inquiry, we are free to consider all resources
    
    available, including decisions of New Mexico courts, other state courts and
    
    federal courts, in addition to the general weight and trend of authority.”
    
    Schuchmann, 235 F.3d at 1225. Decisions of intermediate courts, while not
    
    controlling authority, may be evidence for “ascertaining state law which is not to
    
    be disregarded by a federal court unless it is convinced by other persuasive data
    
    that the highest court of the state would decide otherwise.” Rancho Lobo, Ltd.,
    
    303 F.3d at 1202 n.2 (quoting Webco Indus., Inc. v. Thermatool Corp., 278 F.3d
    
    1120, 1132 (10th Cir. 2002) (further internal citations omitted)).
    
          In New Mexico, employment contracts are generally for an indefinite
    
    period and deemed to be at-will. Garcia v. Middle Rio Grande Conservancy
    
    Dist., 918 P.2d 7, 10 (N.M. 1996); see also Hartbarger v. Frank Paxton Co., 857
    
    P.2d 776, 779 (N.M. 1993). “An at-will employment relationship can be
    
    terminated by either party at any time for any reason or no reason, without
    
    liability.” Hartbarger, 857 P.2d at 779. There exist two exceptions to this rule,
    
    however: “wrongful discharge in violation of public policy (retaliatory discharge),
    
    and an implied contract term that restricts the employer’s power to discharge.”

    Id.
    
          A majority of New Mexico at-will employment implied contract cases
    
    address the standard question of whether an implied contract has “restrict[ed] the
    
    employer’s power to discharge.” Id.; see also id. at 786-87 (neither company
    
    policies nor verbal and written statements by employer were sufficiently explicit
    
    to create an implied contract limiting employer’s ability to terminate employee
    
    without just cause); McGinnis v. Honeywell, Inc., 791 P.2d 452, 457-58 (N.M.
    
    1990) (implied contract existed by virtue of company’s published policies that
    
    altered employer’s ability to fire employee at-will); Forrester v. Parker, 606 P.2d
    
    191, 192 (N.M. 1980) (company personnel policy guide sufficient to create
    
    implied contract limiting employer’s right to discharge employee without just
    
    cause); Hudson v. Vill. Inn Pancake House of Albuquerque, Inc., 35 P.3d 313, 318
    
    (N.M. Ct. App. 2001) (policies outlined in handbook and company’s general
    
    adherence to policies, created an implied contract by which company could not
    
    fire employee without just cause, or without following specified procedures);

    employee); Kiedrowski v. Citizens Bank, 893 P.2d 468, 472-73 (N.M. Ct. App.

    material fact warranting implied contract claim to be submitted to jury).

          New Mexico law also makes clear that where an employment relationship
    
    remains at-will, an employee cannot bring a breach of implied contract claim
    
    against her employer for prospective changes the employer makes to the
    
    conditions of employment. See Gormley, 85 P.3d at 259; Stieber, 901 P.2d at
    
    204. AAA New Mexico contends that the facts of Ms. Miller’s case fall squarely
    
    within the ambit of Stieber and Gormley, and Ms. Miller is therefore precluded as
    
    a matter of law from bringing an implied breach of contract claim against AAA
    
    New Mexico for failing to promote her. But a careful examination of Stieber and
    
    Gormley leads us to conclude that the type of implied contract claim raised and
    
    rejected in those cases is distinguishable from the implied contract claim asserted
    
    by Ms. Miller.
    
          In Stieber, the New Mexico Court of Appeals rejected an at-will
    
    employee’s implied breach of contract claim where the employee claimed that
    
    after her employer assigned her job duties representing a promotion, she was later
    
    assigned tasks contrary to the promotion, effectively resulting in a demotion. 901
    
    P.2d at 203-04. In essence, the breach of contract claim was based on the
    
    assumption that the employee had a vested right in the current terms of her
    
    employment, i.e., the duties associated with her promotion. When her employer
    
    changed those terms by requiring her to perform duties not in accord with her
    
    promoted status, she alleged her employer breached the terms of her employment.
    
    
    
                                            -63-
    The court rejected the employee’s argument, reasoning that “an employer’s right
    
    to terminate an employee at will necessarily and logically includes what may be
    
    viewed as a lesser-included right to insist upon prospective changes in the terms
    
    of that employment as condition of continued employment.” Id. at 204. The
    
    court went on to hold that “[n]o breach of contract action may lie where the
    
    employer in an at-will employment relationship may prospectively change the
    
    conditions of employment at will.” Id.
    
          A similar situation was presented in Gormley. There, an at-will employee
    
    had worked for his employer for approximately ten years as a route driver and
    
    delivery man. Gormley, 85 P.3d at 254. His employer eventually assigned him to
    
    a warehouse position which included lighter duties but did not impact his hours or
    
    pay. He was told he could remain in the warehouse position and maintain his
    
    work hours until he retired. Approximately four years later, the employee’s hours
    
    were decreased and his duties altered. He continued working for at least another
    
    year, but subsequently resigned from the position. Id. at 254. He brought an
    
    implied breach of contract claim, asserting he had a contract right to the specified
    
    number of hours and duties promised to him until he retired. Id. at 259. While
    
    the appellate court determined a grant of summary judgment to the employer on
    
    this question was inappropriate, it nonetheless emphasized that on remand,
    
    “resolution of this issue depends on the fact-finder’s determination regarding [the
    
    
    
                                             -64-
    employee’s] employment status.” Id. Citing to Stieber, the court stated that if an
    
    employee remains at-will, “then any claims regarding breach of contract as to
    
    hours and duties would necessarily fail.” Id. at 259.
    
          The type of claims raised and subsequently deemed invalid in Stieber and
    
    Gormley are different from Ms. Miller’s claim. She is not asserting AAA New
    
    Mexico breached a contract with her by altering the terms of her current
    
    employment. Rather, we construe the essence of Ms. Miller’s claim to be that
    
    AAA New Mexico promised to promote her and failed to do so. Hence, Ms.
    
    Miller’s claim is not about her reliance on present employment terms which were
    
    undermined by AAA New Mexico’s alteration of those terms. Instead, she is
    
    contending that AAA New Mexico’s promise regarding future terms was never
    
    fulfilled. We therefore cannot fully agree with AAA New Mexico that Ms.
    
    Miller’s claim is wholly resolved by the rulings in Stieber and Gormley.
    
    Nonetheless, we are persuaded the rule articulated in those cases can legitimately
    
    and logically be extended to bar an at-will employee from bringing a breach of
    
    implied contract claim for an employer’s failure to fulfill a promise to make
    
    future changes to the terms of employment.
    
          If, pursuant to Stieber and Gormley, an at-will employee cannot rely on her
    
    present terms of employment because the employer retains the right to make
    
    prospective changes to the terms and conditions of employment, Stieber, 901 P.2d
    
    
    
                                            -65-
    at 204, then it is reasonable to conclude that an at-will employee is equally barred
    
    from relying on an employer’s statements regarding future changes regarding the
    
    terms of employment. Where an at-will employee cannot bring a breach of
    
    contract claim for alteration of her current terms of employment, a breach of
    
    contract claim for violation of potential future terms appears equally, if not more,
    
    tenuous.
    
          Other jurisdictions addressing a similar issue have rejected at-will
    
    employees’ breach of implied contract claims. See, e.g., Rouse v. Boehringer
    
    Mannhiem Corp., 108 F.3d 859, 859 (8th Cir. 1997) (pursuant to Iowa law, at-will
    
    employee cannot enforce employer’s promise to promote merely by continuing to
    
    work); Shelton v. Ernst & Young, LLP, 143 F. Supp. 2d 982, 991-92 (N.D. Ill.
    
    2001) (under Illinois law, at-will employee cannot bring failure to promote
    
    claim); Edwards v. U.S. Fid. & Guar. Co., 848 F. Supp. 1460, 1465 (N.D. Cal.
    
    1994) (under Maryland law, at-will employee cannot bring breach of contract
    
    claim for rescinded promotion); Rodgers v. Prudential Ins. Co. of Am., 803 F.
    
    Supp. 1024, 1031-32 (M.D. Pa. 1992) (Pennsylvania law precludes at-will
    
    employee from bringing breach of contract claim for employer’s promise to
    
    promote); Moore v. BellSouth Mobility, Inc., 534 S.E.2d 133, 135-36 (Ga. Ct.
    
    App. 2000) (under Georgia law, no claim for failure to promote can be brought by
    
    at-will employee); Tinkham v. Jenny Craig, Inc., 699 N.E.2d 1255, 1257 (Mass.
    
    
    
                                             -66-
    App. Ct. 1998) (under Massachusetts law, promise to promote at-will employee is
    
    illusory). In light of the rationale supporting the Stieber and Gormley decisions,
    
    neither of which has been corrected or undermined by subsequent New Mexico
    
    Supreme Court rulings, coupled with supporting authority from other states, we
    
    predict that if faced with this particular question, the New Mexico Supreme Court
    
    would hold an at-will employee is barred from bringing an implied breach of
    
    contract claim for an employer’s failure to promote. On purely legal grounds,
    
    therefore, we conclude Ms. Miller was barred from bringing her breach of implied
    
    contract claim against AAA New Mexico.
    
    
    
          B. Judgment as a matter of law
    
          Even if we are wrong in divining the decision the New Mexico Supreme
    
    Court would reach on this question, we are persuaded the district court did not err
    
    in granting judgment as a matter of law to AAA New Mexico on Ms. Miller’s
    
    implied breach of contract claim for lack of an evidentiary basis.
    
          As referenced earlier, we review de novo a district court’s grant of
    
    judgment as matter of law under F ED . R. C IV . P. 50(b). Tyler, 232 F.3d at 812;
    
    Corneveaux v. CUNA Mut. Ins. Group, 76 F.3d 1498, 1502 (10th Cir. 1996).
    
    Judgment as a matter of law is only appropriate when “a party has been fully
    
    heard on an issue and there is no legally sufficient evidentiary basis for a
    
    
    
                                            -67-
    reasonable jury to find for that party on that issue.” F ED . R. C IV . P. 50(a)(1). We
    
    review all the evidence in the record, construing it and any inferences therefrom
    
    in favor of the non-moving party, and refraining from making credibility
    
    determinations and weighing evidence. Tyler, 232 F.3d at 812. Thus, “a court
    
    may grant the motion ‘only if the evidence points but one way and is susceptible
    
    to no reasonable inferences which may support the opposing party’s position.’”
    
    Finley v. United States, 82 F.3d 966, 968 (10th Cir. 1996) (quoting Q.E.R., Inc. v.
    
    Hickerson, 880 F.2d 1178, 1180 (10th Cir. 1989)). Even extending to Ms. Miller
    
    the benefit of all reasonable inferences, we cannot conclude the district court
    
    erred in its ruling.
    
           Generally, the New Mexico courts have “upheld findings that there was no
    
    implied contract in cases where the alleged promise by the employer was not
    
    sufficiently explicit.” Hartbarger, 857 P.2d at 780. “An employer creates
    
    expectations by establishing policies or making promises. An implied contract is
    
    created only where an employer creates a reasonable expectation. The
    
    reasonableness of expectations is measured by just how definite, specific, or
    
    explicit has been the representation or conduct relied upon.” Id. at 783. In ruling
    
    in favor of AAA New Mexico, the district court concluded that Ms. Miller failed
    
    to present the jury with anything but evidence of vague and indefinite promises
    
    that her position was being reviewed for an upgrade. The court ruled that none of
    
    
    
                                              -68-
    the promises could give rise to a reasonable expectation of a promotion, or a
    
    promise to retroactively pay Ms. Miller for the additional services she provided
    
    AAA New Mexico in anticipation of her potential upgrade.
    
          In challenging the district court’s ruling, Ms. Miller contends “there was
    
    sufficient evidence for the jury to decide that the statements, policies, conduct
    
    and practices of AAA [New Mexico], in combination, created a reasonable
    
    expectation by Ms. Miller that her position would be upgraded.” Aplt. Br. at 19.
    
    We disagree. Certainly, there were statements made to Ms. Miller which could
    
    have led her to hope the current position which she held would be upgraded and
    
    she would be able to continue to work for AAA New Mexico in the newly created
    
    position. But our review of the record indicates the evidence is simply
    
    insufficient to show that AAA New Mexico’s statements, policies, or practices
    
    were specific enough to create a binding promise upon which Ms. Miller could
    
    reasonably rely. Hartbarger, 857 P.2d at 783.
    
          Ms. Miller first points to sections from AAA New Mexico’s employee
    
    handbook and human resources manual to support her allegation that the policies
    
    outlined in those documents were sufficiently explicit to support her reasonable
    
    expectation that once she had started performing additional duties outside of her
    
    job description, she would be upgraded. We do not agree.
    
          Under New Mexico law, an employee handbook or personnel manual may
    
    
    
                                             -69-
    alter the terms of an at-will relationship and give rise to an implied contract
    
    where the manual “controlled the employer-employee relationship and an
    
    employee could reasonably expect his employer to conform to the procedures it
    
    outlines.” Garcia, 918 P.2d at 11; see also Mealand, 33 P.3d at 292 (“Plaintiff
    
    can prevail if the handbook modifies or supplements a pre-existing oral
    
    employment agreement.”). Moreover, “an implied contract can still exist in spite
    
    of a [handbook] disclaimer, where the employer’s conduct reasonably leads
    
    employees to believe that they will not be terminated without just cause and a fair
    
    procedure.” Kiedrowski, 893 P.2d at 471. We do not question the expansive
    
    nature of the general terms appearing in the AAA New Mexico employee
    
    handbook, nor do we need to question what impact its disclaimer may have had on
    
    Ms. Miller’s at-will employment at AAA New Mexico. Regardless of the
    
    handbook’s terms, we find nothing in it of a sufficiently explicit nature to enable
    
    Ms. Miller to reasonably conclude that AAA New Mexico was obligated to
    
    upgrade her upon her performance of additional duties for the organization.
    
          The employee handbook’s section on compensation contains language
    
    which reads “[t]he objective of the compensation plan is to pay employees for the
    
    total contribution they make to the organization each year, tying employee
    
    performance to meeting organizational goals, and on paying for results, not just
    
    activity and effort.” App., vol. VII at 1565. When discussing promotions, the
    
    
    
                                             -70-
    handbook indicates that
    
          [p]romotional increases are financial rewards which recognize
          increased responsibilities when employees are assigned to a higher
          grade level. Promotional increases are not automatic. . . . When the
          promotion involves an increase of more than four grades, the
          promoting authority must submit a written recommendation to the
          Vice President, outlining the reasons and justification for the
          promotion. Each situation will be reviewed individually to determine
          the appropriate salary increase.
    
     Id. at 1567-68. The handbook also details that
    
           [t]he Club maintains a position classification system whereby each
           position has a unique title and description of duties and
           responsibilities. All positions are ranked in relation to others, and
           positions similar in level of responsibility and complexity are
           classified at the same grade level. The classification plan,
           consisting of all grade level classifications and position titles, is
           evaluated by Human Resources.
    
          Any new classification or reclassification of an existing position will
          be based upon written analysis of the duties and responsibilities
          assigned to the position.
    
          A review of all jobs is periodically conducted by Human Resources.
          Salary ranges will be adjusted periodically as external conditions
          warrant.
    
    Id. at 1569-70. Finally, in discussing temporary assignments, the handbook states
    
          [i]t may be necessary to assign an employee temporarily to a job
          within another salary range because of vacation, illness or other
          reasons. A temporary assignment of this type does not require a
          status change. However, if the assignment exceeds 30 days, Club
          policy requires that a formal change of status be submitted to Human
          Resources.

           First, nothing in the handbook’s statements regarding AAA New Mexico’s
    
    overall objectives regarding its compensation plan, when promotions might be
    
    granted to employees, or how a job might be newly classified or reclassified, is
    
    specific or definite enough for Ms. Miller to believe that she was individually
    
    entitled to have her position upgraded from an hourly post to a regular position.
    
    Rather, the cited portions of the handbook speak in qualified generalities. See id.
    
    at 1565 (“[t]he objective of the compensation plan . . . .”); id. at 1567-68
    
    (“Promotional increases are not automatic. . . . Each situation will be reviewed
    
    individually to determine the appropriate salary increase.”); id. at 1569-70 (“Any
    
    new classification or reclassification of an existing position will be based upon
    
    written analysis of the duties and responsibilities assigned to the position. A
    
    review of all jobs is periodically reviewed by Human Resources. Salary ranges
    
    will be adjusted as periodically external conditions warrant.”) (emphasis added
    
    throughout).
    
           Second, an examination of the procedures outlined in the human resources
    
    manual regarding the creation of new positions not already classified, see id. at
    
           22
             The human resources manual, which will be discussed in more detail
    below, contains highly similar if not identical provisions to those identified in the
    employee handbook. See App., vol. VI at 1320 (objective of compensation plan);
    id. at 1323 (promotion policy); id. at 1325-26 (detailed description of job

    new public affairs post in the PGA department. However, nothing in the human

    for a new position, was obligated to give Ms. Miller the new job. Furthermore,
    
    Mr. Sandy affirmed at trial that there was “nothing novel” about the process by
    
    which the new position was created. Id., vol. IV at 1069.
    
          Ms. Miller’s reliance on the temporary assignment policy does not assist
    
    her. See id., vol. VII at 1567; id., vol. VI at 1323. When she began performing
    
    additional duties in her capacity of “senior clerk” and then “clerk, intermediate,”
    
    she was not performing a job in “another salary range.” Id., vol. VI at 1323. Mr
    
    Sandy testified that Ms. Miller did not qualify for the terms outlined in the
    
    temporary assignments policy because she merely took on “additional
    
    responsibilities in her position as an intermediate clerk. That would not have
    
    been a temporary assignment. That would have been additional responsibilities in
    
    the position.” Id., vol. IV at 1061. Mr. Sandy further indicated that when Ms.
    
    Yager asked Ms. Miller in 1996 if she would be interested in taking on some
    
    public affairs work for the department, “there had been a discussion about the
    
    additional responsibilities and there was a discussion of what the salary would be
    
    for the position, and that’s what was accepted. That would not be a temporary
    
    assignment. That would be a change in duties.” Id. at 1082-83. Moreover, he
    
    
    
                                             -73-
    testified that the temporary assignment policy did not apply to hourly employees
    
    and that “[t]o [his] knowledge, the only people [he knew to] have been on
    
    temporary assignment [were] . . . regular employees within the organization.” Id.
    
    at 1062.
    
          Echoing the arguments she raised in her retaliation claim, Ms. Miller also
    
    points to the AAA Texas office’s migration of Ms. Rougeau into a regular
    
    position as evidence that AAA New Mexico should have done the same for her.
    
    However, as we discussed earlier, we are not convinced the facts concerning Ms.
    
    Rougeau’s advancement are sufficiently analogous to Ms. Miller’s situation to
    
    warrant her belief that the company had a policy of automatically shifting
    
    employees from hourly to regular positions. In particular, in contrast to Ms.
    
    Rougeau’s situation, when Ms. Miller began working for AAA New Mexico there
    
    was no regular position in existence, or even in formulation, in which she could
    
    be employed. Throughout her entire employment at AAA New Mexico, she
    
    worked as an hourly employee with a full understanding of the limitations of such
    
    a position. Nor, unlike Ms. Rougeau, was she promised at the start of her
    
    employment that a regular position would soon be in existence and hers for the
    
    taking. The facts surrounding Ms. Rougeau’s advancement are inapposite to Ms.
    
    Miller’s case and insufficient to support her implied contract claim.
    
          Finally, Ms. Miller contends that AAA New Mexico, primarily through the
    
    
    
                                            -74-
    statements made by Ms. Yager, promised Ms. Miller that she would be upgraded
    
    to a regular position. Based on our review of the record, in which we have given
    
    her the benefit of all reasonable inferences, see Finley, 82 F.3d at 968, we
    
    conclude Ms. Miller has been unable to point to any sufficiently specific promise
    
    made by Ms. Yager upon which she could base a reasonable expectation that she
    
    was going to receive an automatic upgrade.
    
          We, of course, accept Ms. Miller’s assertions that Ms. Yager made
    
    promises and gave assurances that the upgrade process was moving forward and
    
    was going to happen. As Ms. Miller testified, Ms. Yager told her a number of
    
    times she was in the process of seeking an upgrade for her position, and that it
    
    was going to happen soon. See App., vol. III at 642 (company was going to
    
    evaluate positions and “good chance” post would be reclassified and graded at
    
    higher rate); id. at 643 (job review process would take “a few weeks, . . . maybe
    
    two to three months at the most”); id., vol. IV at 1279 (Ms. Yager sent letter to
    
    supervisor requesting positions be upgraded); id., vol. III at 657 (Ms. Miller
    
    “would receive an upgrade and be reclassified based on the information that [Ms.
    
    Yager] received from her management”); id. at 658-59 (upgrade would happen
    
    soon, within a few months); id. at 675 (upgrade process ongoing and would
    
    happen); id., vol. IV at 891 (Ms. Yager included two regular positions in 2000
    
    budget proposal); id., vol. III at 678-79, id., vol. IV at 892-94 (Ms. Yager
    
    
    
                                            -75-
    informed Ms. Miller job was in budget, upgrade would happen soon, and she
    
    could start using business cards); id., vol. III at 684 (despite delays, upgrade
    
    going to take place); id. at 690 (upgrade “just around the corner”); id., vol. IV at
    
    894 (Ms. Yager informed Ms. Miller job study would be completed by end of
    
    year); id., vol. III at 696 (Ms. Yager promised Ms. Miller upgrade was going to
    
    happen).
    
          Ms. Yager’s own testimony affirmed she made promises to Ms. Miller
    
    about the upgrade process. She testified, however, that her promises were more
    
    limited in nature than how Ms. Miller interpreted them. She noted “[w]hat was
    
    promised was the job study, but there was no promise of anything else.” Id., vol.
    
    V at 1161. “I definitely promised that the job study would go on and that there
    
    certainly weren’t any guarantees, but I was doing everything possible to try to
    
    upgrade the positions.” Id. at 1163; see also id., vol. IV at 946 (Ms. Yager
    
    informed Ms. Miller she did not know extent of input she would have in upgrade
    
    process); id. at 891-92 (Ms. Yager noted initial success in keeping positions in
    
    2000 budget, but also that there was a “long way” to go); id., vol. III at 687 (Ms.
    
    Yager unclear about upgrade time line); id. at 702 (Ms. Yager had no idea when
    
    job review process would be completed).
    
          Likewise, while Ms. Yager may have promised Ms. Miller she would
    
    receive an upgrade, the record makes clear that Ms. Yager did not possess the
    
    
    
                                             -76-
    power to fulfill such a promise. See id., vol. IV at 855, 1032 (Automobile Club
    
    of Southern California directs all human resources decisions); id. at 857-58, 872-
    
    76, 1064, id., vol. VI at 1279-80 (Ms. Yager required to ask direct supervisor for
    
    permission to request human resources to perform job study); id., vol. IV at 1037,
    
    id., vol. VI at 1325-26 (final upgrade approval required at executive levels); id.,
    
    vol. IV at 946 (Ms. Yager indicated she did not know extent of input she would
    
    have in upgrade process); id. at 891-92 (Ms. Yager able to keep positions in 2000
    
    budget, but noted there was a “long way” to go); id., vol. III at 687 (Ms. Yager
    
    not clear about timeline for upgrade); id. at 702 (Ms. Yager uninformed as to
    
    when job review process would be completed). Ms. Yager may have genuinely
    
    wanted to upgrade Ms. Miller, and Ms. Miller certainly believed Ms. Yager’s
    
    promises and assurances. Nevertheless, Ms. Miller’s reliance on Ms. Yager’s
    
    promises evinces her lack of an understanding of AAA New Mexico’s job review
    
    and new job creation process.
    
          Finally, regardless of the promises Ms. Yager made, Ms. Miller was unable
    
    to articulate with any specificity the exact nature of what was promised. At most,
    
    Ms. Miller testified she was promised an upgrade. However, she was unable to
    
    state any of the specifics: when exactly the upgrade would occur, what exactly her
    
    anticipated job duties or job title would be, or how she would be compensated.
    
    See id. at 659 (Ms. Miller was not told when upgrade would occur or what
    
    
    
                                             -77-
    compensation she would receive); id., vol. VI at 1296 (Ms. Miller notes in
    
    memorandum to Ms. Bisno that she has “no idea of the job responsibilities and
    
    parameters” or grade classification or salary band of potential new position).
    
          At trial, Ms. Miller argued that her compensation could be properly
    
    calculated based on the pay range finally settled upon for the new position, and
    
    the wage paid to the individual who eventually accepted that post. 23 But, Ms.
    
    Miller has basically worked her way backwards into establishing a personal
    
    conclusion of what she might have been compensated, if she had applied for the
    
    position. She has failed to present any evidence that in the course of her ongoing
    
    discussions with Ms. Yager, she was ever given a specific salary amount of what
    
    she would receive in the new position.
    
          Finally, Ms. Miller was unable to point to any specific promise made to her
    
    that she would receive retroactive payment for the public affairs duties she
    
    performed for AAA New Mexico in her hourly position. First, Ms. Miller stated
    
    at trial that she had “never testified that anyone told me I was going to receive
    
    retroactive compensation.” Id., vol. III at 773. Likewise, all of her statements
    
    about her conversations regarding retroactive pay with Ms. Yager indicate that her
    
    supervisor agreed that she should receive retroactive pay, but never guaranteed
    
    
          23
             The base pay for the new position was just over $40,000, with the market
    rate being $44,308. When the position was finally filled, the new employee’s
    salary, as determined by his experience and qualifications, was $35,000.
    
                                             -78-
    that such payment would occur. See id. at 681, 772 (Ms. Yager expressed opinion
    
    that Ms. Miller should receive retroactive pay for additional duties); id., vol. IV at
    
    950 (Ms. Yager expressed opinion that it was highly unlikely company would give
    
    Ms. Miller retroactive pay). Moreover, Ms. Miller’s prior receipt of retroactive
    
    pay from the company did not necessarily indicate that in the present context,
    
    AAA New Mexico was obliged to pay her retroactively for the additional public
    
    affairs duties she performed. Mr. Sandy testified retroactive pay is generally
    
    awarded when there
    
           was an oversight. If an employee was supposed to be making $12 an
           hour, and the staff form was submitted for $10, and that’s what [the
           company] had been committed to, then yes, we certainly would
           retroact back to that date, if the information supported the situation
           . . . . And also if the manager had committed to paying a person a
           certain amount, and the manager states that’s what they told them,
           but for some reason, when the paperwork was submitted, there’s a
           different amount, then we certainly would honor what the manager
           had committed to.
    
    Id., vol. IV at 1081. 24
    
           Having extensively reviewed the record and giving to Ms. Miller all
    
    inferences in her favor, we conclude the district court did not err in granting
    
    
            He also indicated that where an hourly position is replaced by a regular
           24
    
    position, the hourly employee is not paid retroactively back to date of hire with
    regular pay. Id., vol. IV at 1082. Rather, the date of the position advancement
    serves as the employee’s new date of service for compensation purposes. Id., vol.
    VI at 1328. Hence, even if Ms. Miller had filled the new position, she would not
    have been retroactively compensated for her prior public relations work for AAA
    New Mexico.

    to support her implied contract claim.
