OPINION
PAUL W. GREEN, Justice.This appeal questions whether a fire chief has absolute discretion to terminate a probationary fire fighter. We affirm the trial court’s judgment, which holds the fire chief *550has discretion to discharge probationary fire fighters.
Background
Gina Marie Montemayor passed the fire academy test with a high score. She was also interviewed by a board of three high-ranking fire fighters. When Montemayor learned she had failed the interview, she complained to the district fire chief that she was asked inappropriate questions about sex and religion. In response, the fire department gave Montemayor a second interview, which she passed. The fire chief, however, did not select Montemayor for the academy. Instead, he chose candidates with lower test scores.
Montemayor then sued the City of San Antonio, City Manager Alexander Briseño, the San Antonio Fire Department, and Fire Chief Robert Ojeda (collectively, the City) for injunctive relief and for a declaration that the City violated section 143.026 of the Local Government Code. This statutory provision required the city manager to fill opening fire fighter positions with the applicants having the highest test scores. Montemayor alleged she was passed over in retaliation for her complaints about the review board.
The trial court found the City violated section 143.026 and issued a temporary injunction that permitted Montemayor to enter the academy and that enjoined the City from taking any action to prevent her from completing her studies. Montemayor entered the academy, became an employee of the fire department, and completed the course. The fire department, however, alleged her performance was substandard and refused to place her in a fire station with the other academy graduates.
The City filed a motion for summary judgment arguing the fire chief had sole discretion to fire probationary fire fighters. The City also argued that any claim based on retaliation or discrimination was not ripe because Montemayor had not received a right to sue letter from the Equal Employment Opportunity Commission. Finally, the City alleged the temporary injunction was void because Montemayor had failed to post a bond. Montemayor responded to these arguments and also alleged the fire chiefs action was barred by res judicata because he previously reprimanded her. The trial court granted the summary judgment “upholding the exclusive authority of the Fire Chief to terminate the probationary employment of the Plaintiff.”
Standard and Scope of Review
We review a summary judgment de novo. To prevail on summary judgment, the mov-ant must show there are no genuine issues of material fact and the movant is entitled to judgment as a matter of law. Tex.R. Civ. P. 166a(c); Nixon v. Mr. Property Management, Co., 690 S.W.2d 546, 548-49 (Tex.1985). In deciding whether there is a disputed fact issue precluding summary judgment, evidence favorable to the nonmovant is taken as true. Nixon, 690 S.W.2d at 548-49. Every reasonable inference is indulged in favor of the nonmovant and any doubts resolved in the nonmovant’s favor. Montgomery v. Kennedy, 669 S.W.2d 309, 310-11 (Tex.1984).
As the summary judgment indicates, the narrow issue in this appeal is whether the fire chief had discretion to terminate Monte-mayor’s employment. We need not address whether the temporary injunction was void, whether Montemayor’s retaliation claims were ripe, or whether Montemayor raised fact issues about her performance in the academy.1 See State Farm Fire & Cas. Co. v. S.S., 858 S.W.2d 374, 380 (Tex.1993) (limiting review of a specific summary judgment). Additionally, we need not address Montema-yor’s complaints raised for the first time at oral argument — whether the judgment was supported by the pleadings or whether the city manager, rather than the fire chief, should terminate probationary fire fighters. See Tex.R.App. P. 38.1(h) (requiring briefs to contain argument); Tindle v. Jackson Nat'l Life Ins. Co., 837 S.W.2d 795, 801 (Tex. App. — Dallas 1992, no pet.) (requiring brief*551ing in addition to a Malooly point2); see also San Jacinto River Auth. v. Duke, 783 S.W.2d 209, 210 (Tex.1990) (prohibiting reversal in the absence of properly assigned error).
The Fire Chiefs Discretion
Montemayor asserts the fire chiefs discretion to terminate probationary fire fighters is limited to good cause, while the City contends the fire chiefs discretion is absolute. We agree with the City.
The Local Government Code characterizes a fire fighter, police officer, or academy trainee as a one-year probationary employee. Tex. Looal Gov’t Code Ann. § 143.027(a) (Vernon 1988). During the probationary period, “the department head shall discharge the [probationary] person and remove the person from the payroll if the person’s appointment was not regular or was not made in accordance with this chapter or the commission rules.” Id. § 143.027(b). Once the probationary employee completes the probationary period, the employee “becomes a full-fledged civil service employee and has full civil service protection.” Id. § 143.027(d).
Until the probationary fire fighter completes the probationary period, the fire fighter serves at the discretion of the fire chief. Wells v. City of Houston, 613 F.Supp. 479, 481 (S.D.Tex.1985), aff'd without opinion, 788 F.2d 1563 (5th Cir.1986); see also Sfair v. City of San Antonio, 274 S.W.2d 581, 583 (Tex.Civ.App. — San Antonio 1955, writ refd n.r.e.) (holding that chiefs decision to discharge probationary employee is final and not appealable). The statute’s directive regarding discharge of employees with “irregular” appointments does not limit the authority of the fire chief to discharge probationary fire fighters. See Garcia v. Garcia, 751 S.W.2d 274, 276 (Tex.App. — San Antonio 1988, no writ) (interpreting similar language from the local rules of the Laredo Civil Service Commission).3 Thus, in this case, the fire chief has discretion to either retain or terminate Montemayor.
Montemayor contends the local collective bargaining contract modifies the terms of the statute. The agreement specifically provides:
Persons enrolled in the initial Fire Academy shall hold the position of Fire Fighter Trainee. As such, he shall be considered a civilian employee and is not a member of the bargaining unit covered by this Agreement nor shall he he subject to any terms of this Agreement or of Chapter US Local Government Code.
(Emphasis added). This provision does not apply to Montemayor because she is no longer enrolled in the fire academy. Even if it did apply, it offers Montemayor no protection beyond that of an at-will employee.
According to Montemayor, the fire chiefs decision to terminate her was based on the same conduct that was the basis of a letter of reprimand. Montemayor argues that res judicata should apply to limit the fire chiefs ability to terminate her. She cites no authority, nor have we found any, that would permit res judicata to apply outside the context of judgments. We therefore hold res judicata does not apply in this case.
Justiciable Issue
By suggesting we lack authority to address Montemayor’s claims, the dissent misconstrues the nature of declaratory judgments. Suits for declaratory judgment are preventative in nature and are intended to determine the rights of parties when a controversy has arisen, before any wrong has actually been committed. Cobb v. Harrington, 144 Tex. 360, 366, 190 S.W.2d 709, 713 (1945); Harkins v. Crews, 907 S.W.2d 51, 56 (Tex.App. — San Antonio 1995, writ denied). They are designed “to afford relief from uncertainty and insecurity with respect to rights, status, and other legal relations; and *552[are] to be liberally construed and administered.” Tex. Crv. Prac. & Rem.Code Ann. § 37.002(b) (Vernon 1986).
Although Montemayor had not been fired at the time judgment was rendered, she faced a real controversy because the City refused to assign her to a fire station. In turn, the City also faced a real controversy because, if it continued to deny Montemayor an assignment during her probationary period, she would eventually become a “full-fledged civil service employee,” without the benefit of on-the-job training. Because Montemayor faced an uncertain future, she properly sought declaratory relief. See Krier v. Navarro, 952 S.W.2d 25, 28 (Tex.App. — San Antonio 1997, writ denied) (finding threat to be a justiciable controversy). Accordingly, we have authority to address her claims.
Conclusion
The fire chief had absolute discretion to terminate a probationary fire fighter like Montemayor. Therefore, the trial court did not err in granting the City summary judgment. Accordingly, we affirm the trial court’s judgment.
. Any fact issues about retaliation or discrimination are not material to the legal issue central to this appeal: whether the fire chief has discretion to terminate Montemayor's employment.
. Malooly Bros., Inc. v. Napier, 461 S.W.2d 119, 121 (Tex.1970) (recommending a general point of error stating "the trial court erred in granting summary judgment”).
. Montemayor cites Smith v. City of Houston, 552 S.W.2d 945, 946 (Tex.Civ.App. — Houston [1st Dist.] 1977, no writ), as authority for her argument that the fire chief requires sufficient cause to terminate probationary employees. Smith is limited to Houston’s Civil Service Code and does not apply to police officers or fire fighters. See Wells, 613 F.Supp. at 481.
