**234 At issue in this case is when the limitations period in the Whistleblowers' Protection Act (WPA), MCL 15.361 et seq ., begins running. The defendant Construction Code Authority (CCA) told the plaintiff, one of its inspectors, that he had been terminated by the defendants Imlay City and Elba Township when he showed up for work on March 31, 2014. It was the CCA's action on that day that triggered the running of the limitations period, not the defendants'

**235 earlier decisions to terminate him, as no action was taken by any defendant to effectuate those decisions. We therefore reverse the Court of Appeals' holding that the alleged wrong triggering the running of the limitations period "occurred when the City and Township wrote the letters to the CCA directing the CCA to terminate plaintiff ...." Millar v. Constr. Code Auth. , unpublished per curiam opinion of the Court of Appeals, issued August 4, 2016 (Docket No. 326544), p. 6, 2016 WL 4162613 . We further reverse the Court of Appeals to the extent that it held the plaintiff's WPA claim untimely "even if we were to assume that CCA's *523 conduct was the allegedly wrongful conduct that commenced the 90-day clock," citing as the CCA's alleged wrongful act its "termination of plaintiff's assignments in the City and the Township on March 27, 2014." Id . On March 27, 2014, the CCA drafted its own letter to the plaintiff communicating the bad news from the city and township defendants, but as noted it did nothing to effectuate that decision until March 31. Id .

The statutory limitations period on the plaintiff's WPA claim therefore did not begin running until the CCA took action to alter the plaintiff's employment on March 31, 2014. Because his complaint was filed 87 days later, it was timely filed under MCL 15.363(1). We reverse the Court of Appeals' judgment in part, vacate the Lapeer Circuit Court's March 19, 2015 order granting summary disposition to the defendants, and remand this case to the Lapeer Circuit Court for further proceedings consistent with this opinion. 1

**236 I. FACTS AND PROCEDURAL HISTORY

The plaintiff performed mechanical and plumbing inspection services for the defendant CCA, an inspection and development control agency. The CCA had contracts with, among others, the defendants Imlay City and Elba Township to provide licensed inspections, and the plaintiff had performed numerous inspections within those jurisdictions. On March 11 and March 20, 2014, the defendant city and the defendant township respectively wrote letters to the CCA directing it to terminate the plaintiff's inspection services within their communities. On March 27, the CCA drafted a letter to the plaintiff to do just that; the letter stated that the plaintiff would no longer perform inspections in those communities. 2 But it was not until the plaintiff arrived at work on March 31 that he was given a copy of the CCA's letter notifying him of the decision to terminate his services in the defendant communities. 3 As a result, that same day he was prevented from working in Imlay City.

The plaintiff filed a three-count complaint alleging violation of the WPA, 4 wrongful termination in violation of public policy, and conspiracy to effectuate **237 wrongful termination and violate the WPA. The trial court granted summary disposition on all counts to all the defendants. The court reasoned in relevant part that the WPA claim was time-barred because the WPA *524 violation occurred, at the latest, on March 27, when the CCA drafted its letter, and therefore the plaintiff had filed his claim one day after the 90-day limitations period in MCL 15.363(1) had run. The trial court also concluded that the WPA preempted the plaintiff's public-policy claim. 5 The Court of Appeals affirmed. The plaintiff appealed here, asserting his WPA and public-policy claims but dropping the civil-conspiracy claim. We ordered oral argument on the application and directed the parties to brief "whether the plaintiff's claim under the Whistleblowers' Protection Act was barred by the 90-day limitation period set forth in MCL 15.363(1)." Millar v. Constr. Code Auth. , 500 Mich. 992 , 894 N.W.2d 600 (2017).

II. LEGAL BACKGROUND AND ANALYSIS

This case involves an issue of statutory interpretation, which we review de novo. Whitman v. City of Burton , 493 Mich. 303 , 311, 831 N.W.2d 223 (2013). This means that we review the issue independently, without any required deference to the trial court.

The Whistleblowers' Protection Act, MCL 15.362, provides:

An employer shall not discharge, threaten, or otherwise discriminate against an employee regarding the employee's compensation, terms, conditions, location, or privileges **238 of employment because the employee, or a person acting on behalf of the employee, reports or is about to report, verbally or in writing, a violation or a suspected violation of a law or regulation or rule promulgated pursuant to law of this state, a political subdivision of this state, or the United States to a public body, unless the employee knows that the report is false, or because an employee is requested by a public body to participate in an investigation, hearing, or inquiry held by that public body, or a court action.

MCL 15.363(1), the statute of limitations governing WPA actions, provides that "[a] person who alleges a violation of this act may bring a civil action for appropriate injunctive relief, or actual damages, or both within 90 days after the occurrence of the alleged violation of this act."

The question in this case is what constitutes "the occurrence of the alleged violation of this act" that triggers the running of the statutory limitations period. In Collins v. Comerica Bank , 468 Mich. 628 , 664 N.W.2d 713 (2003), this Court held that the limitations period applicable to claims under the Civil Rights Act (CRA), MCL 37.2101 et seq ., 6 did not begin running until the date the plaintiff was terminated. We rejected the Court of Appeals' contrary conclusion that the plaintiff's cause of action accrued on the last day the plaintiff worked, a date that preceded her termination.

**239 By contrast, in Magee v. DaimlerChrysler Corp. , 472 Mich. 108 , 693 N.W.2d 166 (2005), and Joliet v. Pitoniak , 475 Mich. 30 , 715 N.W.2d 60 (2006), also CRA cases, this Court distinguished Collins and held *525 that the plaintiffs' discrimination claims were untimely because the last date of the alleged discriminatory treatment, and not the employee's separation from employment, started the limitations period. 7 Critical to our rulings in both of those decisions was the fact that neither plaintiff asserted a claim of discriminatory discharge. Magee , 472 Mich. at 112 , 693 N.W.2d 166 (distinguishing Collins because it involved a claim of discriminatory discharge); Joliet , 475 Mich. at 36-37 , 715 N.W.2d 60 (same).

In this case, the Court of Appeals erred by relying on Joliet to conclude that the alleged wrong occurred either when the city and township wrote letters to the CCA directing it to revoke the plaintiff's authority to work in their jurisdictions or when the CCA in turn drafted its letter to the plaintiff carrying out those directions. At the time each letter was written, the plaintiff had no actionable WPA claim because no allegedly discriminatory action had occurred; the defendants intended to curtail the plaintiff's employment responsibilities, but had not taken any action to implement that intent. It was not until that intent was effectuated on March 31, 2014, that the actionable "wrong" occurred and triggered **240 the running of the 90-day limitations period in MCL 15.363(1). See Collins , 468 Mich. at 633 , 664 N.W.2d 713 ("[I]f a discharge has yet to occur, it cannot be said that the last day worked represents the discharge date. Simply put, a claim for discriminatory discharge cannot arise until a claimant has been discharged."). While the plaintiff was not discharged from his employment on March 31 (his employment responsibilities were merely reduced), that fact does not change the conclusion that this case is more analogous to Collins than to Magee and Joliet . The plaintiff showed up for work on March 31 prepared to go perform inspections in Imlay City, in accordance with his typical employment responsibilities, but he was prevented from doing that when the CCA presented him with its March 27 letter. 8 Nothing prevented the plaintiff from working up until that action, and the defendants do not argue that they did anything to implement the termination decision before March 31.

In other words, in order for an actionable wrong under the WPA to have occurred, an employer must have done more than simply make a decision to discriminate against an employee. Instead, the employer must have taken an adverse employment action against the plaintiff. 9 It *526 is the employer's action to **241 implement the decision that triggers the running of the limitations period; not the decision itself. In this case, the CCA took no action to implement its decision to reduce the plaintiff's duties until it gave the plaintiff the letter instructing him to discontinue working in Imlay City and Elba Township.

The flaw in the Court of Appeals' reliance on Joliet is made plain with a simple illustration. The Court of Appeals held that the limitations period began running as to Imlay City on March 11, when it drafted its letter to the CCA directing the agency to terminate the plaintiff. But the plaintiff continued working in Imlay City until March 27. Plainly, no allegedly discriminatory action had "occurr[ed]" as of March 11, because the defendants had not altered the plaintiff's employment in any way. Under the Court of Appeals' view, the plaintiff could have brought suit against Imlay City on March 12 on the basis of the city's letter to the CCA, even though nothing whatsoever changed in the plaintiff's employment. We rejected such an approach in Collins .

Because "the occurrence of the alleged violation" of the WPA did not occur until the CCA allegedly discriminated against the plaintiff with respect to his terms of employment on March 31, 2014, the plaintiff timely filed his WPA claim. Accordingly, the lower courts erred by dismissing it.

III. CONCLUSION

We hold that the Court of Appeals erred by relying on our decision in Joliet to conclude that the statutory limitations period began running before March 31, **242 2014, the day of the "occurrence of the alleged violation of the act." Rather, the rule from Collins applies. We therefore reverse the Court of Appeals judgment in part, vacate the Lapeer Circuit Court's March 19, 2015 order granting summary disposition to the defendants, and remand to the circuit court for further proceedings consistent with this opinion.
