SCHWELB, Associate Judge:
This appeal presents two important questions regarding the application of our recent decision in Carl v. Children’s Hosp., 702 A.2d 159 (D.C.1997) (en banc) (Carl II), in which we expanded in some measure the circumstances under which an “at will” employee may recover against his or her employer in an action for wrongful discharge. Specifically, we must decide
1. whether the standard articulated in Carl II applies retroactively to cases in which the complaining employee was discharged prior to September 23, 1997 (the date on which Carl II was decided); and, if so,
2. whether, under Carl II, Tracie Washington’s sworn allegation that she was discharged in retaliation for attempting to ensure compliance by a fellow employee with District of Columbia health and food regulations was sufficient to preclude entry of summary judgment against her.
We answer both questions in the affirmative.
I.
THE FACTS
A. The plaintiff’s account
In September 1994, Tracie Washington was employed as a dietary aide and cook at the Friendship Terrace Retirement Home in northwest Washington, D.C. The home housed approximately two hundred elderly residents, and its dining room and kitchen were operated by Guest Services, Inc. This case arises from the involuntary termination of Ms. Washington’s employment on September 9 of that year.
The circumstances which allegedly led to Ms. Washington’s discharge are described in an affidavit which she filed in opposition to Guest Services’ motion for summary judgment, and also in Ms. Washington’s pretrial deposition. Briefly, Ms. Washington claims that on September 8, 1994, she was preparing a meal for the residents of the home when a fellow worker, Tyrica Martin, began spraying stainless steel cleaner in the area where Ms. Washington was cooking. Ms. Washington stated in her affidavit that “[t]he spray is poisonous and if it comes into contact with food it renders the food unwholesome and unfit for human consumption.” She asserted that “where I stood I could feel the spray on me and I could see the spray entering the food I was preparing.” Ms. Washington claimed to have been especially concerned about potential contamination of the food because many of the residents of Friendship Terrace were in ill health.
According to Ms. Washington, “[t]he law requires that I not prepare nor serve food unless it is appropriately protected from ... contamination.” Therefore, in an effort to obey the law, Ms. Washington “told to [Ms. Martin] to stop spraying. To me this was a health emergency.”
The events that followed were described by Ms. Washington in her affidavit:
12. The manager heard what I told the employee and called me into his office and told me that when he tells an employee to do something, I do not have the authority to tell the employee not to do it. He stated that he told the employee to spray, and that by me telling the employee to stop spraying that this was insubordination.
13. I explained to the manager that the spray was entering into the food and that the employee was spraying next to open food which was being cooked.
14. The manager accused me of insubordination. He told me to go home. I went [1073]*1073home and when I returned to work the next day I was fired for insubordination. 15. The insubordination I was fired for was for telling the employee to not spray into and around and near the food I was preparing. This was the only act of insubordination I was told that I committed or that I was aware of.
B. The lawsuit.
On February 13, 1996, Ms. Washington filed a complaint against Guest Services, Inc., alleging that her discharge was wrongful. Ms. Washington claimed that her co-worker’s conduct in spraying the food with cleaning fluid contravened applicable District of Columbia health and food regulations,1 and that Guest Services had dismissed her (Ms. Washington) “for protesting safety, health, and food code violations on the part of the defendant.”
On June 17, 1996, Guest Services filed a motion for summary judgment. Guest Services argued that Ms. Washington was an at-will employee2 and that her allegations, even if true,3 did not bring her within the only public policy exception to the at-will employment doctrine that had been recognized by this court at the time. See Adams v. George W. Cochran & Co., 597 A.2d 28, 34 (D.C.1991) (holding that an at-will employee may not be discharged for refusal to violate the law).
On July 23, 1996, the trial judge granted Guest Services’ motion for summary judgment. He held that Ms. Washington
had no legal obligation to prevent food from being contaminated or to complain about others contaminating food. Rather, her obligation was not to prepare or serve unfit food. [Guest Services] did not put her to the choice of disobeying that obligation as the price for keeping her job.
On July 26, 1996, Ms. Washington filed her notice of appeal.
C. The appeal.
Ms. Washington and Guest Services filed their initial briefs in this court on May 8, 1997 and June 3, 1997 respectively. In them submissions, the attorneys debated the question whether Ms. Washington’s allegations, if credited, brought her situation within the Adams exception to the at-will doctrine. The case was scheduled for submission without oral argument on November 4, 1997. The appeal was thus still pending on September 23, 1997, when the en banc court issued its decision in Carl II.
On December 18, 1997, recognizing that Carl II had added a potential new dimension to Ms. Washington’s appeal, this division issued an interim order. Washington v. Guest Servs., Inc., 703 A.2d 646 (D.C.1997) (per curiam) (Washington I). We held in Washington I that the trial judge had properly granted Guest Services’ motion for summary judgment under the law as it existed prior to Carl II. We further directed counsel to submit their views as to whether the law as enunciated in Carl II applies to the present appeal and, if so, whether the entry of summary judgment in Guest Services’ favor remained appropriate.4 Having considered the parties’ supplemental written and oral submissions, we now hold that although the trial [1074]*1074judge’s decision correctly reflected the case law at the time the motion was decided, the basis for his ruling has been superseded by Carl II.
II.
RETROACTIVITY
We first consider the question whether the modification of the at-will doctrine adopted by the en bane court in Carl II applies to cases in which the plaintiff was discharged prior to September 23, 1997. We hold that it does.
A. Mendes v. Johnson.
As a general rule, statutes operate prospectively, while judicial decisions are applied retroactively. United States v. Security Indus. Bank, 459 U.S. 70, 79, 103 S.Ct. 407, 74 L.Ed.2d 235 (1982). When, as in Carl II, a decision of this court articulates a new rule of law, “it is our duty to apply its holding to this case unless equitable considerations require a different result.” Tenants of 2301 E St. N.W. v. District of Columbia Rental Hous. Comm’n, 580 A.2d 622, 628 (D.C.1990) (citing United States v. The Schooner Peggy, 5 U.S. (1 Cranch) 103, 110, 2 L.Ed. 49 (1801)). In such cases, we must presumptively apply the law as it exists at the time of our decision, even though the trial judge’s disposition was correct at the time of his ruling. Id,
The leading District of Columbia case addressing the circumstances under which judicially-crafted changes in the common law áre to be retroactively applied is Mendes v. Johnson, 389 A.2d 781 (D.C.1978) (en banc). In Mendes, the en banc court, overruling prior precedent, held that a tenant may not be evicted from his or her leasehold except by lawful process, and that a landlord who uses self-help to effect the physical dispossession of the tenant is liable in tort for wrongful eviction. Id. at 783-87. Turning to the question whether the new rule announced by the court should be applied retroactively, the court adopted the Supreme Court’s then-current jurisprudence, as articulated in Linkletter v. Walker, 381 U.S. 618, 85 S.Ct. 1731, 14 L.Ed.2d 601 (1965). The Supreme Court had stated in Linkletter that, as a matter of constitutional law, it was neither required to apply a decision retrospectively nor prohibited from doing so. According to Linkletter,
we must ... weigh the merits and demerits in each case by looking to the prior history of the rule in question, its purpose and effect, and whether retrospective operation will further or retard its operation.
Id. at 629, 85 S.Ct. 1731; see also Mendes, 389 A.2d at 788 (quoting Linkletter).
In Mendes, in conformity with the “broad guiding principles of Linkletterthe court adopted a four-point analytical framework for determining whether, and to what extent, a decision overruling prior precedent should be applied retroactively. This framework included
(1) the extent of the reliance of the parties on the old rule (including the degree of justifiable reliance and the hardship which might result to the litigants as a result of retrospective application); (2) avoidance of altering vested contract or property rights; (3) the desire to reward plaintiffs who seek to initiate just changes in the law; and (4) the fear of burdening the administration of justice by disturbing decisions reached under the overruled precedent.
389 A.2d at 789. Analyzing these criteria, the court held in Mendes that the new rule should be given only “partial retroactive effect, i.e., [it] will apply to the instant parties as well as prospective application.” Id. at 792.
B. Beam and Harper.
Mendes v. Johnson was decided twenty years ago. In the intervening years, the Supreme Court has discarded its previous approach to retroactivity — the very approach on which this court based its decision in Mendes.
In 1987, Linkletter v. Walker, the principal authority upon which Mendes was based, was explicitly overruled. See Griffith v. Kentucky, 479 U.S. 314, 322-23, 107 S.Ct. 708, 93 L.Ed.2d 649 (1987) (holding that all “newly declared” rules must be applied retroactively to all criminal eases pending on direct review). The Court explained in Griffith that [1075]*1075the task of making rules of law “on a broad basis” is a legislative one, and that the nature of judicial adjudication requires that the Court adopt new rules in the context of specific cases. Id. at 322, 107 S.Ct. 708. The Court also concluded that “selective application of new rules violates the principle of treating similarly situated [parties] the same.” Id. at 323, 107 S.Ct. 708.
Since Griffith, the rule of retroactive application has been explicitly extended to civil cases. In James B. Beam Distilling Co. v. Georgia, 501 U.S. 529, 111 S.Ct. 2439, 115 L.Ed.2d 481 (1991), a majority of Justices agreed that a rule of federal law, once announced and applied to the parties to the controversy, must be given full retroactive effect by all courts adjudicating federal law. See id. at 540, 111 S.Ct. 2439 (opinion of Souter, J.); id. at 544, 111 S.Ct. 2439 (opinion of White, J.); id. at 548, 111 S.Ct. 2439 (opinion of Marshall, J.); id. at 548-49, 111 S.Ct. 2439 (opinion of Scalia, J.). In Harper v. Virginia Dep’t of Taxation, 509 U.S. 86, 97, 113 S.Ct. 2510, 125 L.Ed.2d 74 (1993), the Court expanded on Beam as follows:
When this Court applies a rule of federal law to the parties before it, that rule is the controlling interpretation of federal law and must be given full retroactive effect in all cases still open on direct review and as to all events, regardless of whether such events predate or postdate our announcement of the rule. This rule extends Griffith ’s ban against “selective application of new rules.” 479 U.S., at 323 [107 S.Ct. 708]. Mindful of the “basic norms of constitutional adjudication” that animated our view of retroactivity in the criminal context, id., at 322 [107 S.Ct. 708], we now prohibit the erection of selective temporal barriers to the application of federal law in non-criminal cases. In both civil and criminal cases, we can scarcely permit “the substantive law [to] shift and spring” according to “the particular equities of [individual parties’] claims” of actual reliance on an old rule and of harm from a retroactive application of the new rule. Beam, supra, at 543 [111 S.Ct. 2439] (opinion of Souter, J.). Our approach to retroactivity heeds the admonition that [t]he Court has no more constitutional authority in civil cases than in criminal cases to disregard current law or to treat similarly situated litigants differently.5
The Court also stated that “the federal law applicable to a particular ease does not turn on whether [the] litigants actually relied on an old rule or how they would suffer from retroactive application of a new one.” Id. at 95 n. 9, 113 S.Ct. 2510 (citation and internal quotation marks omitted).
C. M.A.P. v. Ryan.
The rule is fundamental in our jurisprudence that “no division of this court will overrule a prior decision of this court.” M.A.P. v. Ryan, 285 A.2d 310, 312 (D.C.1971) (footnote omitted). Overruling our precedents can be effected only by this court en banc. Id. Mendes v. Johnson, itself an en banc decision, is thus presumptively binding on us.
“We do not believe, however, that M.A.P. v. Ryan, supra, obliges us to follow, inflexibly, a ruling whose philosophical basis has been substantially undermined by subsequent Supreme Court decisions.” Frendak v. United States, 408 A.2d 364, 379 n. 27 (D.C.1979). Arguably, Beam and Harper have “substantially undermined” our reliance, in Mendes, on the Supreme Court’s former approach to retroactivity issues, as [1076]*1076articulated in Linkletter. Indeed, we think it probable that if Beam and Harper, and not Linkletter, had reflected the Supreme Court’s jurisprudence in 1978, this court would have given its decision in Mendes full retroactive effect'.
Nevertheless, “[t]his court will not lightly deem one of its decisions to have been implicitly overruled and thus stripped of its precedential authority.” Lee v. United States, 668 A.2d 822, 828 (D.C.1995). As a two-judge majority of a three-judge panel, we are especially reluctant to take such a step, although it may well be desirable for the en banc court to revisit Mendes in light of arguably supervening developments during the past two decades. In any event, we think it unnecessary to decide whether Mendes has survived Beam and Harper because, even if it has, then under the Mendes standards, reasonably construed, our decision in Carl II must be retroactively applied to the present case.6
D. The Mendes factors.
We now consider each of the Mendes factors, in the order that they were enumerated by the court in that case.
(1) Reliance.
We stated in Mendes that “[t]he degree of the reliance by the litigants before the court, and in some eases by the public at large, on the legitimacy of the prior rule has played a major role in courts’ analysis of the retroactivity issue.” 389 A.2d at 789. The court thus focused both on reliance in fact (by the parties before the court) and on the right of the public, including other potential litigants, to rely on the previous rule.7 The reliance inquiry is, of course, directed to Guest Services’ reasonable expectations at the time of Ms. Washington’s dismissal, and not to counsel’s subsequent formulations during the course of litigation.
In the present case, Guest Services’ own submission to the trial court belies any notion that it discharged Ms. Washington in actual reliance on prior law as reflected in Adams, supra.8 Guest Services represented to the court that Ms. Washington was terminated for rudeness, hysterical conduct, and insubordination. If these were the actual reasons for Ms. Washington’s discharge, then no “public policy” exception to the at-will doctrine was implicated, for it is undisputed that Guest Services would have had the right to fire Ms. Washington on the stated grounds even under Carl II standards.9
[1077]*1077We turn next to the other aspect of the reliance inquiry, namely, whether employers and the general public relied, or could reasonably have relied, on the proposition that Adams represented, and would continue to represent, the sole public policy exception to the employment at-will doctrine. The question, as we see it, is whether the pre-Carl II standard was so deeply ingrained in the law that it would be unreasonable to apply Carl II retroactively even as to employers who have failed to demonstrate reliance in fact on prior case law.
Guest Services contends that, at the time Ms. Washington was 'discharged, an attorney could properly have advised his or her client, with reasonable certainty, that, if the facts were as Ms. Washington alleged them to be, then at that time, the client had no reason to fear liability for wrongful discharge. But in any case in which retroactive application is sought, the defendant’s conduct would always have been lawful under previously applicable precedent. Indeed, in Mendes, the landlord was held liable for damages even though, as the court noted, he reasonably “might have assumed, on the basis of prior case law, that his conduct was permissible.” Mendes, supra, 389 A.2d at 793.
This is not a case in which the prior state of the law was so clear as to provide Guest Services with reasonable assurance that its discharge of Ms. Washington would not give rise to liability. As a majority of the en banc court recognized in Carl II, supra, 702 A.2d at 160,
[w]e could not and did not hold in Adams that [the exception recognized by the court in that case] was the only public policy exception, because that question was simply not presented.
(Emphasis in original) (citations and internal quotation marks omitted).10 Indeed, the jurisprudence of wrongful termination was uncertain in 1994, when Ms. Washington was terminated by Guest Services, and remains somewhat fluid today. In recent years, as the courts have developed the “emerging doctrinal basis for the public policy exception,” Martin Marietta Corp. v. Lorenz, 823 P.2d 100, 113 (Colo.1992), the at-will doctrine has been “undergoing considerable erosion.” Boudar v. Buenette, 106 N.M. 279, 742 P.2d 491, 494 (1987) (en banc). To paraphrase the Supreme Court of California, “[e]ven if one views [Carl II] as breaking new and unexpected ground, a point we do not concede, it did so in an indisputably unsettled area.” Newman v. Emerson Radio Corp., 48 Cal.3d 973, 258 Cal.Rptr. 592, 772 P.2d 1059, 1068 (1989).11
By the time Guest Services discharged Ms. Washington, the “public policy” exception to the at-will doctrine had been widely applied in other jurisdictions to categories of conduct similar to that in which Ms. Washington claims to have engaged. See generally 82 Am.Jur.2d Wrongful Discharge § 15, at 688 (1992) (explaining that “the courts generally protect three categories of protected employee conduct: (1) exercising a statutory right or civil obligation; (2) refusing to engage in illegal activity; [and] (3) reporting criminal conduct to supervisors or outside agencies”).
The District of Columbia was not insulated from this trend. In 1992, two years before the events giving rise to this appeal, this court had agreed to consider a “public policy exception” case en banc, but had subsequently aborted the venture. See Gray, supra note 10. It was therefore reasonably fore[1078]*1078seeable that the en banc court might look at the issue again.12 Finally, the Supreme Court’s decisions in Beam and Harper, considered in conjunction with Mendes and the virtually unanimous holdings of the courts of other jurisdictions in wrongful termination cases, see Part II.E, infra, arguably gave employers fair warning that any expansion of the public policy exception which this court might elect to undertake could well receive retroactive application.
To summarize, Guest Services has demonstrated neither that it actually relied on prior law nor that, if it had, such hypothetical reliance would have been reasonable. In our view, therefore, the first Mendes factor tilts in Ms. Washington’s favor.
(2)Avoidance of altering vested contract or property rights.
“In conjunction with the reliance factor, courts also weigh the probable effect of a law change on the vested property or contract rights of the parties.” Mendes, supra, 389 A.2d at 790. Guest Services has cited no authority, however, and we know of none, for the proposition that it had a “vested” right to discharge Ms. Washington.13 As we have demonstrated in our discussion of Mendes’ “reliance prong,” Guest Services’ assertion that the dismissal of Ms. Washington was lawful was cast in doubt by readily discerna-ble uncertainty as to the future course of a developing area of the law.
Guest Services may have had a subjective expectation that no further exception to the at-will doctrine would become applicable to Guest Services’ conduct. Such an expectation may even have stemmed from a plausible predictive assessment of how the law would develop in the District of Columbia. Plausibility is not enough, however, to Create the kind of vested right that a court should take care not to impair. The application of Carl II to this appeal will not deprive Guest Services of any legally cognizable vested right.
(3) Rewards to plaintiffs who seek to change the law.
Ms. Washington did not bring this action to effect a change in the law. On the contrary, her counsel has maintained, erroneously in our view, that she is entitled to prevail under the law in effect prior to our decision in Carl II. Mendes’ “reward” factor does not weigh in favor of retroactive application of Carl II to Ms. Washington.
(4) Fear of burdening the administration of justice with retroactive changes in the law.
In connection with the fourth Mendes factor, Guest Services asserts that “[a] full retroactive change would open the floodgates of litigation based on wrongful discharge.” We do not find this contention persuasive.
If “floodgates” were going to open in the wrongful termination area, this would surely have happened as a result of the Carl II decision itself, and not on account of a ruling applying Carl II retroactively to the limited number of potential litigants whose claims are not barred by the three-year statute of limitations. See D.C.Code §§ 12-301(7)-(8) (1995).
In any event, “the flood of litigation argument is nothing more that an unarticulated fear of the mythological Pandora’s box....” Note, Protecting At-Will Employees Against Wrongful Discharge: The Duty to Terminate Only in Good Faith, 93 Haev.L.Rev. 1816, 1842 n. 146 (1980) (quoting Geary v. United States Steel Corp., 456 Pa. 171, 319 A.2d 174, 182 (1974) (Roberts, J., dissenting)).14 Our en bane court emphatically re-[1079]*1079jeeted an identical contention in Williams v. Baker, 572 A.2d 1062, 1067-68 (D.C.1990) (en banc). Dean Prosser said it well many years ago:
It is the business of the law to remedy wrongs that deserve it, even at the expense of a “flood of litigation”; and it is a pitiful confession of incompetence on the part of any court of justice to deny relief upon the ground that it will give the courts too much work to do.
Prosser, Intentional Infliction of Mental Suffering: A New Tort, 37 Mich.L.Rev. 874 (1989);15 see also W. Page Keeton, Prosser and Keeton on the Law of Torts, § 12, at 56 (5th ed.1984) (paraphrasing and elaborating on Prosser’s earlier discussion).
In Mendes, the court also gave consideration to the question whether retroactive application of its decision would require the relitigation of cases already decided under prior law. 389 A.2d at 792 n. 25. Nothing in this opinion, however, contemplates the application of the new Carl II standard in cases which have come to final judgment and in which all direct appeals have been exhausted. See, e.g., Dowell v. State Farm Fire & Cas. Auto. Ins. Co., 993 F.2d 46, 48 (4th Cir.1993) (after appeals have been exhausted, final judgment will not be reopened on basis of change in decisional law). There is no evidence that a substantial number of appeals now pending potentially present the question whether Carl II is to be applied retroactively, and the handful of cases in that category would not significantly burden our courts.
E. Decisions in other jurisdictions.
Although there is no dispositive District of Columbia precedent, case law in other jurisdictions overwhelmingly supports our conclusion that decisions recognizing or expanding the public policy exception to the at-will doctrine should be retroactively applied. See, e.g., Bernstein v. Aetna Life & Cos., 843 F.2d 359, 363-64 (9th Cir.1988) (applying Arizona law); Martin Marietta Corp., supra, 823 P.2d at 110-14 (Supreme Court of Colorado); Newman, supra, 258 Cal.Rptr. 592, 772 P.2d at 1062-72 (Supreme Court of California); McGehee v. Florafax Int’l, Inc., 776 P.2d 852, 853-54 (Okl.1989) (Supreme Court of Oklahoma); Barnes v. Chase Instruments Corp., 1986 WL 6616, 1986 Term. Lexis 3068 (Tenn.App.1986); but cf. Bimbo v. Burdette Tomlin Mem. Hosp., 644 F.Supp. 1033, 1039-40 (D.N.J.1986). Most of these cases were decided before Beam and Harper, but the courts nevertheless held that retroactive application was appropriate under the Supreme Court’s prior jurisprudence, as reflected in Linkletter, supra, and Chevron Oil Co. v. Huson, 404 U.S. 97, 92 S.Ct. 349, 30 L.Ed.2d 296 (1971). We agree with the following analysis of the issue, on different but comparable facts, by the Supreme Court of Oklahoma:
Unfairness and undue hardship would be imposed upon discharged employees by a merely prospective application of the Burk decision.16 Appellant would be deprived of an actionable tort claim for his employer’s alleged violation of a clear expression of public policy found in the perjury statute. [Statutory citation omitted.] In contrast, no inequity will result from the retroactive application of Burk. Employers accused of violating clear expressions of public policy cannot be said to have justifiably relied on the employment-at-will doctrine.
Nor will appellees in this action be substantially harmed by being forced, at a new trial, to present evidence that appellant’s discharge was motivated by poor employee performance rather than his refusal to sign false small claims affidavits. Appellees’ claim of “good-faith reliance” on the employment-at-will doctrine cannot justify its alleged tortious fixing for an employee’s refusal to commit a crime. No “manifest injustice” will result from requir[1080]*1080ing appellees to defend against appellant’s claim.
McGehee, supra, 776 P.2d at 854.
* * * * * *
After considering all of the Mendes factors and the authorities in other jurisdictions, we conclude that the Carl II decision should be applied to Ms. Washington in this case.
III.
THE APPLICATION OF CARL II TO THE PRESENT RECORD
We now turn to the question whether the order granting summary judgment in favor of Guest Services can continue to stand if we apply the en banc court’s subsequent decision in Carl II. We conclude that it cannot.
Linda Carl alleged in her complaint that Children’s Hospital had discharged her from her position as a nurse because, inter alia, she had testified before the Council of the District of Columbia in opposition to tort reform legislation. The trial court dismissed her complaint on the ground that her allegations were insufficient to bring her case within what was then the sole declared public policy exception to the at-will doctrine, as articulated in Adams. A division of this court affirmed. Carl v. Children’s Hosp., 657 A.2d 286 (D.C.1995) (Carl I). The full court granted Ms. Carl’s petition for rehearing en banc.
In support of her claim of wrongful termination, Ms. Carl placed her principal reliance on D.C.Code § 1-224 (1992). Section 1-224 makes it a criminal offense “corruptly or by threat of force, or by any threatening letter or communication, [to] endeavorf] to influence, intimidate or impede any witness in any proceeding pending before the Council-” Ms. Carl did not allege that Children’s Hospital had threatened her or had otherwise violated the proscriptions of § 1-224, nor did she claim that the statute created a private right of action. Rather, Ms. Carl argued that her termination for testifying before the Council contravened a public policy exception to the at-will doctrine, and that it was therefore actionable. A majority of the en banc court held that Ms. Carl’s complaint stated a claim upon which relief could be granted because it fell within a public policy “solidly based” on, or “firmly anchored” in, Section 1-224. Carl II, supra, 702 A.2d at 163-64 & n. 6 (Terry, J., concurring).
Our disposition of Carl II mandates reversal of the summary judgment in the present case. The health and food regulations which we have cited in footnote 1, supra, are expressions of a clear public policy proscribing, in the interest of public health, the preparation, service or sale of adulterated or contaminated food. Conduct that imperils the health and safety of the elderly residents of a retirement home, who, as a group, are particularly vulnerable to the kind of practice here alleged, is obviously contrary to the public policy of this jurisdiction, and Guest Services has not seriously-argued the contrary.
Ms. Washington has alleged, under oath, that she was discharged for attempting to persuade her fellow worker (and, ultimately, her employer) not to violate this officially declared public policy and for protesting an alleged unsafe and unlawful practice. To permit an employee to be fired for sueh actions would undermine the purposes of the food and health regulations and would frustrate the public policy of which these regulations are an expression. If a cook who attempts to prevent the contamination of the food that she is preparing can lose her job for “insubordination,” then similarly situated employees are likely to be coerced into silence, and the safety of the food will be compromised. Indeed, in the present case, the supervisor’s intervention, if it occurred as Ms. Washington claims, had the immediate potential consequence of permitting Tyrica Martin to continue to spray the residents’ food with a poisonous cleaning fluid.17 The relationship between Ms. Washington’s discharge and the applicable public policy was thus closer in time and more palpable than in Carl II.
[1081]*1081It may be, of course, that Ms. Washington’s allegations will not be sustained at trial. On Guest Services’ motion for summary judgment, however, we view the record in the light most favorable to Ms. Washington, and we must treat her sworn affidavit and deposition testimony as true. See, e.g., Graff v. Malawer, 592 A.2d 1038, 1040 (D.C.1991).18 If the events occurred as Ms. Washington has alleged, then an impartial trier of fact could reasonably conclude that Ms. Washington was discharged for conduct protected by a public policy exception to the employment at-will doctrine, and that her termination was therefore wrongful.
IV.
CONCLUSION
For the foregoing reasons, the judgment of the trial court is reversed. The ease is remanded for further proceedings consistent with this opinion.
So ordered.
