OPINION BY
Judge LEAVITT.The American Federation of State, County and Municipal Employees, District Council 87 (Union) appeals an order of the Court of Common Pleas of Lackawanna County (trial court) denying Union’s motion to vacate an arbitration award. The arbitrator held that the County of Lacka-wanna (County) did not violate the anti-discretion or seniority clauses in the collective bargaining agreement by hiring a female detention officer to deal with female juvenile offenders, as it had been ordered to do by the trial court. Union argues that the trial court erred because the arbitrator’s award did not draw its essence from the collective bargaining agreement. Concluding that the trial court did not err, we affirm.
On June 17, 2010, the Court of Common Pleas of Lackawanna County, by the Honorable Trish Corbett, entered an order, later memorialized in writing on September 15, 2011, directing the County to hire a female detention officer to work the day shift from 7:00 a.m. to 3:00 p.m. at the County’s juvenile detention facility (Juvenile Facility). The County did so, and Union responded with two grievances. The matter went before an arbitrator in accordance with the Public Employe Relations Act, Act of July 23,1970, P.L. 563, as amended, 43 P.S. §§ 1101.101-1101.2301 (PERA).1 At the grievance hearing, Union presented the testimony of Frank Gal-li, steward of the Juvenile Facility. The County presented the testimony of Clifford Hoffman, the director of the Juvenile Facility, and Nancy Pearson, the deputy director of human resources for the County.
The Juvenile Facility is an all-male juvenile detention center and is the only juvenile detention center in Lackawanna County. The Juvenile Facility may not house female offenders, who must be transferred to a female juvenile detention facility. The nearest female juvenile detention facilities *1287are in Tioga and Lancaster counties. The Juvenile Facility is responsible for transporting female juvenile offenders to one of these neighboring detention facilities.
Because the Juvenile Facility may not place female offenders in its cells, these offenders must wait in the Juvenile Facility’s office until transportation can be arranged. Due to flight concerns, an officer must sit with female offenders while they wait for transportation. The Juvenile Facility’s policy requires the presence of a female officer when female offenders are transported to neighboring juvenile detention facilities. According to Hoffman,
it’s better to have a female. There’s times we’ve actually had to pull over a car and restrain a female because she would get out of hand in the back of our vehicle. And like I said, it’s a liability to let a female go into a bathroom by herself. You don’t know if she’s actually smuggled anything with her. So, it’s definitely a plus and it also saves liability towards the county if two males are in the car driving a female down. The female could accuse the two males of anything she pretty much wants. A female with us lends more credibility to nothing has happened.
Reproduced Record at 77a (R.R. — ). Because the Juvenile Facility has only male employees, female offenders cannot be transferred until the County can arrange to have female employees from other departments supervise the transfer.
Frequently, it takes an entire shift to find a female employee, usually a female probation officer, who is available for the transfer. Hoffman explained the complications that arise from this situation:
[W]e took volunteers from the juvenile and adult probation departments, they’re all females. They’re actually working for me at that time, they’re not on their traditional work hours. I can’t interfere with the traditional work hours of any of the probation officers. They’re doing it, actually, on their own. And they’re on a paid on call status.
R.R. 74a. Hoffman explained that when a female probation officer is not available, the “female [offender] would have to sit until 4:00 pm.... So that means that somebody could be locked up at 10:00 a.m. and have to sit until 4:00 before they even get on the road.” R.R. 78a. Additionally, according to Hoffman, the “average round trip is six hours.” R.R. 71a. Hoffman also testified that between 50 and 80 percent of all female juvenile offender transfers occur during the day shift.
Hoffman testified about problems that developed with the Juvenile Facility’s transfer system in 2010:
Our number of transports really increased in 2010. In the past, like I said, we’ve done 10 females, 18 females in one year and our population shot up to 53 in 2010. And then plus that, with the layoffs and everything within the county, other departments were also shorthanded and couldn’t loan us anybody to do those transports anymore.
R.R. 82a. These problems came to the attention of the trial court, specifically, the Honorable Trish Corbett, who had presided over “several cases” where “females [were] getting locked up at 10 or 11 o’clock in the morning and [had] to wait until 4 o’clock in the afternoon to be transported.” R.R. 86a. On June 17, 2010, Judge Cor-bett, apparently sua sponte, ordered the Juvenile Facility to hire a female detention officer for the day shift. Accordingly, on August 6, 2010, the Juvenile Facility posted a job opening on its website, stating that it was seeking a female juvenile detention officer.2
*1288Shortly thereafter, in October of 2010, Juvenile Detention Officer Finlon was hired to -fill the position. She was hired even though twelve other male officers outranked her in seniority. Moreover, Officer Finlon’s hiring required a male officer, Chris Gardir, who had previously worked the day shift at the Juvenile Facility, to be moved to another shift.3
In October and December of 2010, Union filed two grievances to challenge the hiring of Officer Finlon, which, it asserted, violated the CBA provision forbidding the consideration of gender in hiring decisions. The matter went before an arbitrator. The arbitrator held that the County did not violate the CBA. Union filed a petition with the trial court to vacate the arbitrator’s order. The trial court denied Union’s motion on January 8, 2014, and Union appealed to this Court.
On appeal, Union contends the arbitrator’s award must be vacated because it fails to satisfy the “essence test,” which requires that an arbitrator’s award draw its essence from a collective bargaining agreement. Specifically, Union contends that the arbitrator’s award was not rationally derived from the terms of the CBA for four reasons. First, the arbitrator’s award contradicts the CBA’s proscription against gender bias in hiring. Second, the arbitrator focused on Union’s delay in filing a grievance, which was irrelevant. Third, the arbitrator misinterpreted the provision of the CBA that requires female personnel for transportation of female detainees. Fourth, the trial court lacked the authority to order the County to hire a detention officer at the Juvenile Facility. The County counters fhat because this Court must give deference to the arbitrator’s award, we may not substitute our interpretation of the CBA for the arbitrator’s.
We begin by examining an appellate court’s standard of review of an arbitrator’s award. In Westmoreland Intermediate Unit #7 v. Westmoreland Intermediate Unit # 7 Classroom Assistants Educational Support Personnel Association, PSEA/NEA 595 Pa. 648, 939 A.2d 855, 857 (2007), our Supreme Court reaffirmed that “the essence test [is] the proper standard to be employed by a court when reviewing a grievance arbitration award.” In Westmoreland, a classroom assistant was fired after she suffered a bad reaction while wearing a Fentanyl patch on school grounds for which she did not have a prescription. Her union filed a grievance, arguing that the school lacked just cause for discharging her. The matter went before an arbitrator who agreed with the union. Accordingly, the arbitrator reinstated the classroom assistant, without back pay and with strict rehabilitation requirements.
On appeal, our Supreme Court observed:
If the heart of PERA is Section 401, which recognizes the right of certain public employees to organize for pur*1289poses of collective bargaining/[4] ... then its lifeblood is the requirement that labor disputes arising under a collective bargaining agreement be resolved by final and binding arbitration/[5]
Westmoreland, 939 A.2d at 861 (internal citations omitted). Our Supreme Court further explained that because our legislature’s intent in enacting PERA was to reduce the expense of litigation and increase the speed and efficiency of resolving disputes, it should remain a rare circumstance where a court overturns an award of an arbitrator. According to the Supreme Court, “regular vacating of arbitration awards ... would add time and expense to the process and it would take the resolution of disputes from a person chosen by the parties and give it to a court to decide.” Id. at 862. Therefore, “[t]he standard [of review] is one characterized by great deference.” Id.
The Supreme Court then reaffirmed the deferential “essence test” for judicial review of arbitration awards, explaining the appropriate analysis as follows:
First, the court shall determine if the issue as properly defined is within the terms of the collective bargaining agreement. Second, if the issue is embraced by the agreement, and thus appropriately before the arbitrator, the arbitrator’s award will be upheld if the arbitrator’s interpretation can rationally be derived from the collective bargaining agreement.
Id. at 863 (quoting State System of Higher Education (Cheyney University) v. State College and Professional Association (PSEA-NEA), 560 Pa. 135, 743 A.2d 405, 413 (1999)). The Court explained the essence test more succinctly: “a court will only vacate an arbitrator’s award where the award is indisputably and genuinely without foundation in, or fails to logically flow from, the collective bargaining agreement.” Westmoreland, 939 A.2d at 863 (emphasis added). With this deferential standard of review in mind, we consider Union’s arguments, which concern only the second prong of the essence test, i.e., whether the arbitrator’s award is rationally derived from the CBA.
*1290Union first contends that the arbitrator’s award contradicts Article 15 of the CBA, which states:
Section 1. All promotions shall be filled by employees already in the bargaining unit who possess the seniority, skill and ability to perform such duties when skills and ability are equal, seniority of the employee shall prevail. When a vacancy occurs within a classification (for shifts, days off, preferred duties etc.) the person possessing the minimum skill and most seniority shall prevail.
Section 2. Posting of Vacancies
When the County determines to fill a vacancy (including newly created positions or additions to the present complement) in the bargaining unit at the Prison, the County will post notice of such vacancy for a period of ten (10) work days. The notice shall state which job(s) are open, how many openings exist, what qualifications are required, how the bid is to be made and what is the time limit for filing the same. The County and Union discourage the costly practice of indiscriminate bidding for individual convenience or temporary advantage. For promotions and transfers, the County •will fill the vacancy within thirty (30) days from the last date of the posting. For external hires, the County will fill the vacancy within ninety (90) days of the last date of the posting. Employees who wish to apply for the vacancy shall in writing indicate their qualification for the job and file their bid within the prescribed time limit.
Section 8. Bumps and Bids: All positions will be posted and bid in January of each year, which all Correctional Officers and Sergeants at the Prison and all Juvenile Detention Officers at the Detention Center shall have the right to bid by seniority regardless of gender. Any vacancy that occurs during the year (except promotions) will be posted and awarded to the most senior employee who has not previously executed a bid. Employee shall have only one bid per calendar year. Submitting a bid for employee’s current shift while required shall not be considered a bid for this purpose.
R.R. 19a-20a (emphasis added).6 Union contends that the arbitrator’s award cannot be sustained because it “undermined the importance that the CBA places in seniority[.]” Brief of Appellant at 22.
The problem with Union’s argument is that it ignores the arbitrator’s reliance on Article 29, Section 11 of the CBA, which states: “Juvenile Detention officers who are required to transport female detainees must be accompanied by qualified female personnel.” R.R. 33a. Union argues that the Arbitrator erred in equating “female personnel” with “female Detention Officers.” Essentially, Union asks this Court to substitute its judgment for the arbitrator on how.to reconcile conflicting provisions of the CBA. The essence test does not permit this Court to vacate an arbitrator’s award even if we disagree with the arbitrator’s interpretation of the CBA. Central Susquehanna Intermediate Unit Education Association v. Central Susquehanna Intermediate Unit #16, 74 Pa. Cmwlth. 248, 459 A.2d 889, 890 (1983). The arbitrator resolved the meaning of different provisions in the CBA in favor of the specific provision in Article 29, which specified a female must be involved in transporting female detainees. We cannot *1291say that the arbitrator’s interpretation was not rationally derived from the CBA, i.e., “indisputably and genuinely [is] without a foundation in ... the collective bargaining agreement.” Westmoreland, 939 A.2d at 863.
Next, Union contends that “the Arbitrator erroneously argue[d] that somehow AFSCME’s failure to file a grievance when the job was originally posted undermines Union’s challenge to the County’s failure to allow for bidding to fill the position.” Union Brief at 23. This argument lacks merit. Although the arbitrator did make this complaint, it was obiter dictum. It did not affect the outcome, which turned on the arbitrator’s conclusion that Article 29 of the CBA trumped Article 15.
In its third argument, Union contends that Article 29 does not trump Article 15 because “[n]either [Union] nor the County relied upon Article 29, Section 11 in their [sic] presentations at the hearing.” Union Brief at 24. An arbitrator’s interpretation of a CBA is guided by general contract construction principles. Greater Nanticoke Area School District v. Greater Nanticoke Area Education Association, 760 A.2d 1214, 1219 (Pa.Cmwlth.2000). A contract’s construction requires a consideration of the entire contract to decipher its intent. Keenan v. Scott Township Authority, 151 Pa.Cmwlth. 225, 616 A.2d 751, 754 (1992). Here, the arbitrator’s examination of the entire CBA was consistent with, not contrary to, his obligation to make an award that draws its essence from the collective bargaining agreement.
In its final assignment of error, Union contends that Judge Corbett lacked the authority to make hiring decisions for the Juvenile Facility. According to Union, the arbitrator erred in concluding that the trial court was “specifically charged with oversight of the Juvenile Detention Center.” Arbitrator’s Award, April 22, 2013, at 6. Our Supreme Court has held that the “courts of this Commonwealth under our Constitution have certain inherent rights and powers to do all such things as are reasonably necessary for the administration of justice.” Sweet v. Pennsylvania Labor Relations Board, County of Washington, 457 Pa. 456, 322 A.2d 362, 365 (1974). In the case sub judice, Judge Cor-bett ordered the Juvenile Facility to hire a female detention officer for the day shift in order to transport female juvenile detainees to female detention facilities in a reasonably prompt manner. This appears related to the “administration of justice.” However, it matters not to this appeal whether the trial court’s order was appropriate or not. A trial court’s order cannot be set aside by an arbitrator but only by a court of law. Union never appealed or challenged the court order that triggered the County’s hiring of Officer Finlon to a tribunal with jurisdiction to correct an improvident court order. The arbitrator was not such a tribunal.
For the foregoing reasons, we affirm.
ORDER
AND NOW, this 24th day of October, 2014, the order of the Court of Common Pleas of Lackawanna County dated January 8, 2014, in the above-captioned matter is hereby AFFIRMED.
. One grievance filed by Union concerns the County's requirement that the Juvenile Facility must hire a non-senior female officer, ■ which is contrary to the terms of the CBA. The other grievance concerns the detention officer that was displaced by the hiring of a female detention officer. Both grievances rely on the same set of facts and arguments.
. The job opening on the website was titled "Juvenile Detention Officer.” R.R. 48a. The job description read:
The purpose of this job is to maintain order and supervise the conduct of the residents at the Lackawanna County Juvenile Detention Center. The female detention officer is responsible for the prevention of escape, through physical means if necessary, maintaining discipline, and providing guidance to the residents during their adjustment and stay at the detention center and will also be responsible for assisting all female juvenile detainees before and after sentencing.
R.R. 48a.
. Detention Officer Gardir has been permitted to remain employed during the day shift until the present matter is resolved.
. Section 401 of PERA states:
It shall be lawful for public employes to organize, form, join or assist in employe organizations or to engage in lawful concerted activities for the purpose of collective bargaining or other mutual aid and protection or to bargain collectively through representatives of their own free choice and such employes shall also have the right to refrain from any or all such activities, except as may be required pursuant to a maintenance of membership provision in a collective bargaining agreement.
43 P.S. § 1101.401.
. The requirement referenced by the Pennsylvania Supreme Court comes from Section 903 of PERA, which states:
Arbitration of disputes or grievances arising out of the interpretation of the provisions of a collective bargaining agreement is mandatory. The procedure to be adopted is a proper subject of bargaining with the proviso that the final step shall provide for a binding decision by an arbitrator or a tripartite board of arbitrators as the parties may agree. Any decisions of the arbitrator or arbitrators requiring legislation will only be effective if such legislation is enacted:
(1) If the parties cannot voluntarily agree upon the selection of an arbitrator, the parties shall notify the Bureau of Mediation of their inability to do so. The Bureau of Mediation shall then submit to the parties the names of seven arbitrators. Each party shall alternately strike a name until one name remains. The public employer shall strike the first name. The person remaining shall be the arbitrator. (2) The costs of arbitration shall be shared equally by the parties. Fees paid to arbitrators shall be based on a schedule established by the Bureau of Mediation.
43 P.S. § 1101.903.
. Union also cites other provisions of the CBA relating to hiring and promotion as evidence that the arbitrator’s award does not rationally derive from the CBA. However, because the Union cites these provisions to bolster its argument that the arbitrator incorrectly interpreted the CBA, the cited provisions do not change our analysis or conclusion.
