Misconduct Your Employer Discovers After Firing You Does Not Erase the Claim — It Cuts Off Reinstatement and Front Pay and Stops the Back-Pay Clock on the Day of Discovery

The holding is two rulings pointing in opposite directions

Christine McKennon worked for the Nashville Banner Publishing Company for about 30 years and was 62 when she lost her job. She sued under the Age Discrimination in Employment Act. In her deposition she testified that during her final year she had copied several confidential documents about the company’s finances, taken the copies home, and showed them to her husband — for “insurance” and “protection,” because she thought she was about to be fired for her age. A few days later the company sent her a second termination letter, saying that the copying violated her job responsibilities and that had it known, it would have discharged her at once for that reason. McKennon v. Nashville Banner Publishing Co., 513 U.S. 352, 354–55 (1995).

The district court and the Sixth Circuit both held she could recover nothing. The Supreme Court reversed, on an assumption that made the question clean: that age was the sole reason for the discharge, and that the copying was grave enough that immediate discharge would have followed its disclosure in any event. On those premises, at 356:

We do question the legal conclusion reached by those courts that after-acquired evidence of wrongdoing which would have resulted in discharge bars employees from any relief under the ADEA. That ruling is incorrect.

The reason is chronology. At 360:

The employer could not have been motivated by knowledge it did not have and it cannot now claim that the employee was fired for the nondiscriminatory reason.

That is the first ruling, and it is the one employees are told least often. The second ruling is the one they are told most often, usually without the first, and it is a limit on remedies rather than on liability.

The employer has to prove the discharge would have happened, and it goes first

The remedial limits are not free. McKennon, at 362–63:

Where an employer seeks to rely upon after-acquired evidence of wrongdoing, it must first establish that the wrongdoing was of such severity that the employee in fact would have been terminated on those grounds alone if the employer had known of it at the time of the discharge.

Read the verbs. Must first establish — the burden is the employer’s and it is a threshold. Of such severity — not any policy violation, and not any inaccuracy on a résumé. In fact would have been terminated — not that the employer could have fired the employee, and not that the conduct was a fireable offense in the abstract, but that this employer would have done it. On those grounds alone — the misconduct has to carry the discharge by itself.

McKennon itself did not test that showing. The Court took it as given: the lower courts had found no basis for contesting the premise, and the Court said that “for purposes of our review we need not question it here.” Id. at 356. So the opinion states the standard and does not illustrate it.

What it does to each remedy

Reinstatement and front pay. At 361–62:

We do conclude that here, and as a general rule in cases of this type, neither reinstatement nor front pay is an appropriate remedy. It would be both inequitable and pointless to order the reinstatement of someone the employer would have terminated, and will terminate, in any event and upon lawful grounds.

“As a general rule in cases of this type” is a general rule, not an absolute one, and the sentence immediately before it in the same paragraph says the boundaries of relief in this class of cases “must be addressed by the judicial system in the ordinary course of further decisions, for the factual permutations and the equitable considerations they raise will vary from case to case.” Id. at 361.

Back pay. The Court called this “a more difficult problem” and answered it with a starting point rather than a cutoff. Id. at 362:

Once an employer learns about employee wrongdoing that would lead to a legitimate discharge, we cannot require the employer to ignore the information, even if it is acquired during the course of discovery in a suit against the employer and even if the information might have gone undiscovered absent the suit. The beginning point in the trial court’s formulation of a remedy should be calculation of backpay from the date of the unlawful discharge to the date the new information was discovered. In determining the appropriate order for relief, the court can consider taking into further account extraordinary equitable circumstances that affect the legitimate interests of either party. An absolute rule barring any recovery of backpay, however, would undermine the ADEA’s objective of forcing employers to consider and examine their motivations, and of penalizing them for employment decisions that spring from age discrimination.

Three things are in that paragraph and they are usually collapsed into one. The clock runs from the unlawful discharge to the date of discovery. That window is a beginning point, and the court may adjust it for “extraordinary equitable circumstances” — a phrase that does not favor either side on its face. And a rule of no back pay at all was rejected outright.

Attorney’s fees, and the discovery problem. The Court took up the obvious objection — that this rule invites employers to go looking. At 363:

The concern that employers might as a routine matter undertake extensive discovery into an employee’s background or performance on the job to resist claims under the Act is not an insubstantial one, but we think the authority of the courts to award attorney’s fees, mandated under the statute, 29 U. S. C. §§ 216(b), 626(b), and to invoke the appropriate provisions of the Federal Rules of Civil Procedure will deter most abuses.

That is a prediction about deterrence, not a rule limiting discovery, and the opinion supplies no test for when a background search crosses a line.

What McKennon is, and what it is not

It is a decision construing the ADEA, whose remedial provision authorizes a court to “grant such legal or equitable relief as may be appropriate to effectuate the purposes of [the Act].” McKennon, 513 U.S. at 358 (quoting 29 U.S.C. § 626(b)). The Court reasoned from the equitable character of that authority, from the unclean-hands doctrine and its limits, and from what it called “the duality between the legitimate interests of the employer and the important claims of the employee.” McKennon, 513 U.S. at 361.

It is not a decision about Minnesota statutes, and it says nothing about what a Minnesota court should do with a claim under chapter 363A or Minn. Stat. § 181.932.

Minnesota: what the statutes say, and what the search found

The two Minnesota employment statutes most likely to carry a discharge claim write their remedies differently from the ADEA, and the difference matters to how the McKennon question would even be framed.

The Human Rights Act. Reinstatement and back pay are not automatic in Minnesota to begin with. Minn. Stat. § 363A.33, subd. 9(1), provides that in an employment case “the court may order: (i) the hiring, reinstatement, or upgrading of an aggrieved party who has suffered discrimination, with or without back pay.” Minn. Stat. § 363A.29, subd. 5(1), gives an administrative law judge the same menu in the same permissive form. Back pay is written into the statute as an optional companion to a reinstatement order, and every item on the list is introduced by “may.”

Sitting beside that discretionary list is a mandatory damages sentence that is not back pay at all. Section 363A.33, subd. 8(a), directs that “[i]n all cases where the court finds that the respondent has engaged in an unfair discriminatory practice, the court shall order the respondent to pay an aggrieved party who has suffered discrimination compensatory damages, including mental anguish or suffering, in an amount up to three times the actual damages sustained.” The full architecture of chapter 363A’s remedies — the mandatory orders, the civil penalty that is paid to the state, punitive damages under Minn. Stat. § 549.20, and fees — is set out on what the Human Rights Act can award and is not repeated here. What is worth naming here is the structural point: a doctrine built to cabin equitable relief and back pay does not map cleanly onto a statute whose mandatory remedy is a multiplied compensatory award.

The Whistleblower Act. Minn. Stat. § 181.935(c):

If the district court determines that a violation of section 181.932 occurred, the court may order any appropriate relief, including but not limited to reinstatement, back pay, restoration of lost service credit, if appropriate, compensatory damages, and the expungement of any adverse records of an employee who was the subject of the alleged acts of misconduct.

“May order any appropriate relief” is discretion written in the broadest terms the Legislature had available, and reinstatement and back pay appear inside an open-ended list. Paragraph (a) separately authorizes a civil action “to recover any and all damages recoverable at law, together with costs and disbursements, including reasonable attorney’s fees,” and “such injunctive and other equitable relief as determined by the court.”

The search. No published Minnesota appellate decision adopting, rejecting, or applying the McKennon remedial limits under the Human Rights Act or the Whistleblower Act was located by the searches run for this page. Those searches, and their limits, are listed in this guide’s citation manifest: the Caselaw Access Project archive of the North Western Reporter, Second Series, was queried by case name, and the Minnesota State Law Library archive and general web indexes were queried for the phrase “after-acquired evidence” together with Minnesota employment terms. CourtListener, which is the only full-text case search this site uses, was unavailable on the date this page was written, so no full-text search of Minnesota appellate opinions was run. One Minnesota Court of Appeals decision surfaced in a general index and was not retrieved and is not cited, because the index identified it as a nonprecedential opinion. That is a report of what was searched and what came back. It is not a statement that no Minnesota decision exists.

What can be said from a retrieved Minnesota source is how a Minnesota court would approach a federal doctrine it has not adopted. In Henry v. Independent School District #625, No. A21-0004 (Minn. Feb. 8, 2023), the supreme court said it twice while working through a different federal import: federal law “provides a useful starting point given our limited case law on constructive discharge,” slip op. at 21, and, on declining a requirement several federal courts impose, “we emphasize again that we are not bound by federal law in our application of the Human Rights Act,” slip op. at 27. A useful starting point, and not a rule.

Why this doctrine shows up in a case that has nothing to do with lying

The McKennon pattern needs only two facts: a discharge the employee says was unlawful, and a rule the employee broke that nobody was looking at until the lawsuit started. Résumé and application inaccuracies are the familiar version. The doctrine as the Court wrote it is not limited to them — McKennon itself involved copying internal financial documents during employment, not a misstatement at hiring — and the opinion draws no line between misconduct at the door and misconduct on the job.

Neither does it say where the misconduct has to be discovered. The Court expressly contemplated discovery in the litigation itself: an employer cannot be required “to ignore the information, even if it is acquired during the course of discovery in a suit against the employer and even if the information might have gone undiscovered absent the suit.” McKennon, 513 U.S. at 362.

What does not change is the threshold. The employer still has to establish that the wrongdoing was severe enough that this employee “in fact would have been terminated on those grounds alone.” McKennon, 513 U.S. at 362–63. An employer that has kept other employees who did the same thing has a problem with that sentence, and so does an employer whose written policy treats the conduct as something less than a discharge offense. Your personnel file and the employer’s own policy documents are where that showing is tested.

What this page does not do

It describes a Supreme Court decision and reads two Minnesota remedy statutes against it. It does not evaluate a separation, and it does not tell you whether anything in your file would clear McKennon’s severity threshold, because that turns on the employer’s own rules and on how the employer has treated other people under them.

Related reading on the site: whether the firing was unlawful in the first place is the threshold question; the remedies the Human Rights Act actually authorizes are on their own page; the Whistleblower Act’s remedies, the jury right, and the fee provision are on the remedies page.
