ADEA Claims After Muldrow: Workplace Harm Does Not Replace Proof of Discriminatory Causation

Case: Li Men v. Inguran, LLC
Court: United States Court of Appeals for the Seventh Circuit
Decided: November 2, 2026
Disposition: Summary judgment for the employer affirmed.

Precedential status: The court expressly designated this order a nonprecedential disposition, to be cited in accordance with Federal Rule of Appellate Procedure 32.1. It applies existing law rather than establishing a new binding circuit precedent.

1. Introduction

This decision illustrates a distinction central to employment-discrimination litigation: showing that an employer took an adverse action is different from showing that the employer acted for an unlawful reason. Although recent precedent has reduced the degree of workplace harm necessary to support a discrimination claim, an employee must still produce evidence connecting the challenged treatment to discrimination or retaliation.

Li Men challenged disciplinary warnings, a negative performance evaluation, and her eventual termination by Inguran, LLC under the Age Discrimination in Employment Act (ADEA). She also alleged retaliation after reporting possible age discrimination to human resources. The Seventh Circuit affirmed summary judgment because the evidence did not permit a reasonable jury to find the necessary discriminatory or retaliatory connection.

The court nevertheless accepted an important part of Men’s legal argument: reprimands and negative evaluations need not produce separate “tangible job consequences” to qualify as adverse employment actions in an ADEA discrimination case. That clarification did not change the outcome because her claims failed on causation.

2. Background and Procedural History

Workplace disputes and disciplinary action

Men began working as an Inguran laboratory technician in 2014, when she was 44. Her manager, Katiana Oliveira, was seven years younger.

In March 2020, Oliveira observed Men handling two test tubes simultaneously, contrary to company procedures. Men attributed the incident to forgetting a recent procedural change. The two disputed who had raised her voice and interrupted the other. Oliveira issued a written warning describing procedural violations and insubordinate or disrespectful conduct.

A second dispute arose on June 16, 2022, while Oliveira was on vacation. Men questioned instructions from acting supervisor Elise Christiansen because she had not understood that Christiansen was in charge. Human resources officer Jalyn Boles acknowledged that there had been miscommunication but instructed Men to follow Christiansen’s directions. Men then complied.

The next day, Men emailed Boles that she could not tell whether Oliveira disliked her because of her race, age, or another reason. She also described perceived ridicule of her accent, yelling, and differential treatment. The record did not establish that Boles shared this email with Oliveira.

On July 8, Oliveira issued another written warning based on the June incident. Men disputed the warning and repeatedly sought its withdrawal. The record also contained reports of laboratory errors, including a contaminated sample and a misplaced sample, along with complaints about her workplace attitude.

The performance evaluation and reduction in force

Oliveira completed employee evaluations on July 14, 2022. Men received mostly low scores, accompanied by comments about following instructions and complying with supervisory directions.

During a reduction in force that August, Inguran terminated three laboratory technicians: Men, aged 52; Benjamin Swayze, aged 19; and Joshua Dudley, aged 32. All three had received low evaluations.

Men emphasized that Inguran retained another 19-year-old employee, Leeroy Olivares, whose evaluation score was lower than hers. Inguran’s evidence, however, distinguished Olivares from Men because his record did not include insubordinate or disrespectful conduct toward a supervisor.

District court proceedings

Representing herself, Men sued in April 2024. The district court granted summary judgment to Inguran on both discrimination and retaliation. It also denied her request to amend her complaint a third time to add emotional-distress allegations and a state-law claim for intentional infliction of emotional distress. Men obtained representation on appeal.

3. Summary of the Opinion

  • Age discrimination: Retaining one younger employee with a lower evaluation score did not, in the context of the whole record, establish that Inguran selected Men for termination because of age.
  • Retaliation: Men identified no evidence that Oliveira knew about her discrimination complaint, and she did not show that Inguran’s stated reasons were pretextual.
  • Adverse employment actions: The district court’s insistence on “tangible job consequences” was too restrictive under intervening discrimination precedent. Nevertheless, treating the warning and evaluation as actionable would not cure the absence of evidence of age-based causation.
  • Amendment: Denying a third amended complaint was within the district court’s discretion because the proposed claim lacked newly identified supporting allegations and would require additional discovery, causing delay and prejudice.

4. Analysis

A. Standards of appellate review

The court reviewed summary judgment de novo, independently examining whether the evidence presented a genuine dispute of material fact. Under Federal Rule of Civil Procedure 56(a), judgment is appropriate when no such dispute exists and the moving party is entitled to judgment as a matter of law.

This standard does not authorize a court to resolve genuine credibility disputes. But a disagreement about whether discipline was fair does not necessarily create a factual dispute about whether it was discriminatory. The evidence must support a reasonable inference of unlawful motivation.

By contrast, the denial of leave to amend was reviewed for abuse of discretion. That more deferential standard recognizes the district court’s authority to manage litigation and assess the practical consequences of late amendments.

B. Precedents cited and their influence

Oest v. Ill. Dep't. of Corrs., 240 F.3d 605, 613 (7th Cir. 2001)

The district court relied on this decision to conclude that Men’s warning and negative evaluation were not adverse employment actions because they lacked “tangible job consequences.” It therefore treated termination as the only actionable employment decision.

The appellate court explained that subsequent authority no longer supported that restrictive threshold for discrimination claims. Its discussion should not be read as formally overruling every aspect of Oest v. Ill. Dep't. of Corrs.; rather, it identifies why the particular requirement applied below could not control after the newer cases.

Markel Ins. Co. v. Rau, 954 F.3d 1012, 1016 (7th Cir. 2020)

This case supplied the appellate standard for reviewing summary judgment: an independent assessment without deference to the district court’s legal conclusion. The opinion also cited its instruction that, when considering cross-motions, evidence must be construed in favor of the party opposing the particular motion under consideration.

Its role was procedural rather than substantive. It framed how the court evaluated the record, not what constitutes age discrimination.

Franzoni v. Hartmarx Corp., 300 F.3d 767, 773 (7th Cir. 2002)

The district court cited this authority for the rule that the ADEA does not authorize damages for pain and suffering. That rule explained why Men could not simply expand the remedies available under her existing federal claims to include emotional-distress compensation.

A separate state-law tort claim presents a different issue. The unavailability of emotional-distress damages under the ADEA does not, by itself, establish that every independent state-law claim is invalid. The appellate court upheld denial of amendment on the additional grounds of inadequate supporting allegations, delay, and prejudice; it did not announce a general bar against related state-law tort claims.

Muldrow v. City of St. Louis, 601 U.S. 346, 359 (2024)

This Supreme Court decision was central to correcting the district court’s adverse-action analysis. As quoted in the order, a Title VII discrimination plaintiff must “show only some injury respecting [their] employment terms or conditions.”

The significance is that an employee need not always identify a separate, substantial economic consequence before challenging discriminatory workplace treatment. Nevertheless, some employment-related injury remains necessary. The decision does not make every criticism or unfavorable evaluation automatically actionable, and it does not remove the requirement to prove discrimination.

Arnold v. United Airlines, Inc., 142 F.4th 460, 470 & n.21 (7th Cir. 2025)

This decision provided the link between Muldrow v. City of St. Louis, which concerned Title VII, and Men’s ADEA discrimination claims. The Seventh Circuit explained that it had already extended the “some injury” approach to age-discrimination cases.

Accordingly, Men was correct that the absence of separate tangible consequences did not necessarily exclude her warning and evaluation. But this authority addressed the injury threshold, not whether age caused the challenged actions.

C. Age discrimination: evaluating the entire comparison

Men’s principal argument was straightforward: Inguran claimed to select employees based on poor performance, yet retained a much younger employee whose numerical evaluation was worse. She argued that this inconsistency could expose the stated justification as pretext.

The court rejected that inference on this record for two reasons.

  1. The broader termination pattern did not support her proposed inference. Inguran also dismissed two substantially younger employees whose evaluation scores were better than Men’s. The court therefore declined to assess Olivares’s retention in isolation.
  2. Evaluation totals did not capture every relevant distinction. Unlike Men, Olivares had no record of insubordinate or disrespectful behavior toward a supervisor. Inguran thus had an additional nondiscriminatory basis for distinguishing them.

The reasoning does not establish that terminating younger employees automatically defeats an older employee’s discrimination claim. Nor does it establish that retaining a younger, lower-rated employee can never support an inference of discrimination. Its narrower point is that comparator evidence must be considered alongside relevant differences and the surrounding employment decisions.

The court also did not treat numerical rankings as a mandatory layoff formula. Men needed evidence that the employer’s explanation concealed age discrimination, not merely evidence that another selection method could have favored her.

D. Workplace injury and discriminatory causation remain separate questions

The order’s most important doctrinal distinction is between the existence of an adverse employment action and its cause.

The court accepted that warnings and evaluations can qualify as adverse actions without accompanying tangible consequences. It did not conclusively decide that each challenged action in Men’s case satisfied the revised standard. Instead, it assumed that possibility and held that the claims still failed because no evidence permitted a finding that Inguran acted because of her age.

That approach explains why the district court’s overly restrictive threshold did not require reversal. Correcting one part of the legal analysis could not supply the missing proof on another independently necessary part of the claim.

E. Retaliation: knowledge, timing, and pretext

Men relied on the proximity between her June complaint and the subsequent discipline and termination. The district court treated her email as arguably protected activity, but both courts found the causal evidence insufficient.

The first difficulty was decisionmaker knowledge. Although Boles received the email, Men identified no evidence that Oliveira knew she had complained of possible discrimination. Knowledge held by a human resources recipient does not, without further evidence, establish that the supervisor responsible for the challenged conduct knew about the complaint.

The second difficulty was the employer’s supported explanation. The court pointed to Men’s performance review and documented laboratory mistakes, and found no evidence that Inguran’s explanation was pretextual.

The order therefore does not declare that suspicious timing is irrelevant or can never support retaliation. It holds that timing did not overcome the specific evidentiary gaps here. Moreover, although the discussion of workplace harm appears near the retaliation analysis, the court expressly described the extension of Muldrow v. City of St. Louis to ADEA discrimination claims. The order should not be read as resolving a separate adverse-action standard for retaliation claims.

F. Amendment: litigation stage and practical prejudice

The proposed third amendment came after extensive discovery and Men’s deposition. Men acknowledged that she would need additional discovery, including medical assessments, to support the new emotional-distress claim. Inguran would likewise have needed discovery into entirely new issues.

The appellate court emphasized both the absence of newly identified supporting factual allegations and the resulting delay and prejudice. Its ruling concerns whether the late amendment should have been permitted in this litigation; it does not adjudicate the elements of a properly pleaded intentional-infliction-of-emotional-distress claim.

5. Potential Impact

Although nonprecedential, the order offers several practical lessons:

  • Older adverse-action formulations require care. Courts assessing ADEA discrimination claims must account for the reduced injury threshold recognized through Muldrow v. City of St. Louis and Arnold v. United Airlines, Inc.
  • A lower injury threshold does not lower the causation requirement. Employees must still connect the challenged treatment to age or protected activity.
  • Comparator evidence is contextual. Numerical scores, disciplinary histories, and the broader selection pattern may all affect whether a comparison supports an inference of discrimination.
  • Retaliation cases require attention to information flow. Evidence about who received a complaint, who learned of it, and who made the challenged decision can be decisive.
  • Late tort claims require more than a request for additional damages. Supporting allegations and the discovery consequences of amendment matter independently of the remedies available under federal discrimination law.

For future litigants, the decision is most useful as an illustration of existing principles operating together, rather than as an independent source of binding doctrine.

6. Complex Concepts Simplified

Summary judgment
A decision without trial when the evidence does not create a genuine dispute requiring a jury to resolve a legally important fact.
Adverse employment action
Employer conduct causing legally sufficient workplace harm. For ADEA discrimination claims, the opinion recognizes that separate tangible consequences are not always required.
Causation
The connection between an unlawful reason and an employment decision. Unpleasant treatment alone does not establish that age or a discrimination complaint caused it.
Pretext
A stated explanation that conceals the real reason for an action. A decision can be disputed or arguably unfair without its explanation necessarily being a cover for discrimination.
Comparator evidence
A comparison with another employee used to suggest unequal treatment. Its strength depends on whether relevant circumstances are sufficiently alike.
Protected activity
Conduct protected against retaliation, such as opposing suspected unlawful discrimination. The courts assumed or treated Men’s email as arguably qualifying, without finding sufficient evidence of retaliatory causation.
Abuse of discretion
A review standard allowing a trial court reasonable latitude in managing matters such as late amendments and additional discovery.

7. Conclusion

The Seventh Circuit affirmed because Men’s evidence did not reasonably connect Inguran’s actions to age discrimination or retaliation. Her successful objection to the district court’s restrictive workplace-harm standard could not remedy that missing causal proof.

The order’s central lesson is therefore limited but important: broader recognition of actionable workplace injury does not dispense with evidence of unlawful motivation. Its separate amendment ruling also underscores the need to plead new claims with factual support and before they would substantially disrupt completed discovery.
