Sixth Circuit Reaffirms the “Severe or Pervasive” Hostile-Environment Standard After Muldrow and Rejects § 504 Rehabilitation Act Retaliation

1. Introduction

Tara Miller, an African American woman hired at age 50 as a probationary human-resources assistant at the Detroit VA medical center, alleged workplace discrimination and harassment based on race, sex, age, and disability (PTSD related to military sexual trauma). She sued the United States Department of Veterans Affairs and the Secretary under Title VII, the ADEA, and the Rehabilitation Act, asserting discrimination, retaliation, and hostile work environment.

The factual narrative featured: (i) two early incidents Miller characterized as sexual harassment by her supervisor (a “Candy Man” comment and alleged “ogling”); (ii) ongoing interpersonal conflicts with coworkers; (iii) alleged disparagement of her mental condition; and (iv) performance and conduct issues, including failure to follow instructions and improper access to coworkers’ personnel files. The VA terminated Miller during her probationary period.

The district court granted summary judgment to Defendants on all claims. On appeal, the Sixth Circuit affirmed across the board, focusing on evidentiary and procedural deficiencies (failure to establish prima facie cases and forfeiture), the absence of statutorily protected activity for retaliation, and the continued vitality of the “severe or pervasive” hostile-environment standard notwithstanding the Supreme Court’s language in Muldrow.

2. Summary of the Opinion

A. Discrimination (Title VII / ADEA / Rehabilitation Act)

• Title VII (race/sex): Affirmed because Miller did not meaningfully pursue race- or sex-based discrimination in response to summary judgment; the court treated those claims as abandoned.
• ADEA and Rehabilitation Act discrimination: Affirmed because Miller failed to address Defendants’ argument that she could not establish a prima facie case; she attempted to build a prima facie showing only on appeal, which the court deemed forfeited.

B. Retaliation (Title VII / ADEA / Rehabilitation Act)

• Rehabilitation Act retaliation: Rejected categorically under Smith v. Mich. Dep't of Corr., holding that “§ 504 of the Rehabilitation Act does not provide a cause of action for retaliation.”
• Title VII / ADEA retaliation: Affirmed because Miller neither preserved a prima facie showing in the district court nor demonstrated “protected activity”; her internal complaints were treated as general workplace grievances rather than opposition to unlawful discrimination.

C. Hostile Work Environment (Title VII / ADEA / Rehabilitation Act)

• Affirmed because most alleged conduct was not “based on” a protected characteristic; the remaining allegations (two sexualized incidents and disability-related remarks) were not sufficiently “severe or pervasive.”
• The court rejected Miller’s argument that Muldrow v. City of St. Louis reduced the standard to “some harm,” explaining that Sixth Circuit law continues to require “severe and pervasive” harassment.

3. Analysis

3.1 Precedents Cited (and how they drove the result)

Summary judgment framework and appellate posture.

• Hunt v. Sycamore Cmty. Sch. Dist. Bd. of Educ. and Helphenstine v. Lewis County (quoting Wilmington Tr. Co. v. AEP Generating Co.) supplied the de novo standard and the “no genuine dispute of material fact” rule.
• Marshall v. The Rawlings Co. (quoting Laster v. City of Kalamazoo) framed burden allocation: once Defendants point to the absence of evidence, the nonmovant must identify specific facts for trial.
• Celotex Corp. v. Catrett was pivotal: the court treated Miller’s failure to make a showing on essential elements (prima facie cases) as dispositive at summary judgment.
• Preservation/forfeiture/abandonment controlled the appeal:
  • Bennett v. Hurley Med. Ctr. supported deeming claims abandoned when a litigant fails to address them in response to summary judgment.
  • Jackson v. Genesee Cnty. Rd. Comm'n and Mich. Bell Tel. Co. v. Strand foreclosed new prima facie theories raised first on appeal.

Discrimination: direct vs. circumstantial proof and the McDonnell Douglas structure.

• The court relied on:
  • Barrett v. Whirlpool Corp. (Title VII) and Blizzard v. Marion Tech. Coll. (ADEA) for the principle that discrimination may be proven through direct or circumstantial evidence.
  • Crocker v. Runyon for the same proposition under the Rehabilitation Act.
  • McDonnell Douglas Corp. v. Green and Tex. Dep't of Cmty. Affs. v. Burdine
  • Geiger v. Tower Auto. and Burns v. City of Columbus, Dep't of Pub. Safety, Div. of Police to apply McDonnell Douglas to ADEA and Rehabilitation Act claims.
• For prima facie elements, the panel cited:
  • Hall v. Baptist Mem'l Health Care Corp. (Title VII) and Willard v. Huntington Ford, Inc. (ADEA) for the “similarly situated / replacement” fourth element.
  • Bledsoe v. Tenn. Valley Auth. Bd. of Dirs. (quoting Jones v. Potter) for Rehabilitation Act prima facie requirements, including employer knowledge of disability and replacement by a nondisabled person or an open position.
• Policastro v. Nw. Airlines, Inc. functioned as a doctrinal “gate”: failure at the prima facie stage ends the analysis without reaching legitimate reason or pretext (including “after-acquired evidence” arguments).

Retaliation: protected activity and statutory limits.

• Dixon v. Gonzales provided the McDonnell Douglas/Burdine approach for retaliation.
• The prima facie retaliation standard came from Warf v. U.S. Dep't of Veterans Affs. (quoting Nguyen v. City of Cleveland), and Blizzard v. Marion Tech. Coll. for ADEA retaliation.
• The scope of “protected activity” was defined via:
  • Wasek v. Arrow Energy Servs., Inc. (Title VII) and Weigel v. Baptist Hosp. of E. Tenn. (ADEA) for the opposition/participation categories.
  • Fox v. Eagle Distrib. Co. for the key limiting rule: complaints must reference or concern unlawful discrimination, not merely unfairness or conflict.
• Smith v. Mich. Dep't of Corr. delivered the categorical holding that § 504 of the Rehabilitation Act provides no retaliation cause of action—ending that claim without factual inquiry.
• White v. Standard Ins. Co. reinforced that pretext is reached only after a prima facie case is established.

Hostile work environment: “based on” protected status; severity/pervasiveness; and Muldrow’s role.

• Elements came from:
  • Phillips v. UAW Int'l (Title VII race hostile environment).
  • Smith v. Rock-Tenn Servs., Inc. (sex), McNeal v. City of Blue Ash (age), and Bryant v. McDonough (disability).
• Excluding non-protected-category conduct relied on Bowman v. Shawnee State Univ.: only harassment “based upon” a protected characteristic counts in the hostile-environment calculus.
• The objective/subjective “severe and pervasive” requirement was anchored in Ogbonna-McGruder v. Austin Peay State Univ., which in turn applied Harris v. Forklift Sys. factors.
• Comparing the alleged sex-based incidents to prior Sixth Circuit outcomes, the court used:
  • Nathan v. Great Lakes Water Auth. (multiple breast-related comments insufficient).
  • Clark v. United Parcel Serv., Inc. (vulgar jokes and physical boundary-crossing still insufficient on that record).
• For disability-related hostility, Kellar v. Yunion, Inc. was central: performance discussions and skepticism about a condition generally do not amount to actionable hostility; the court treated “crazy/no common sense/mental ability” remarks as falling within this line.
• To reject vague assertions, the court invoked Viet v. Le (quoting Alexander v. CareSource) against conclusory statements.
• Finally, the court harmonized Muldrow v. City of St. Louis with Sixth Circuit hostile-environment doctrine via McNeal v. City of Blue Ash and Kellar v. Yunion, Inc.: “some harm” does not lower the liability test; it describes the harm that severe-or-pervasive harassment causes—leaving an employee “worse off” in employment terms or conditions.

3.2 Legal Reasoning

The opinion’s reasoning is best understood as three interlocking moves: (1) procedural discipline (issues not contested in response to summary judgment are lost, and new arguments cannot be raised first on appeal); (2) statutory gatekeeping (no retaliation claim exists under § 504 of the Rehabilitation Act in this Circuit); and (3) substantive thresholds (complaints must actually oppose discrimination to be “protected activity,” and hostile-environment claims require harassment that is both “based on” a protected trait and sufficiently severe or pervasive).

On discrimination and retaliation, the panel largely affirmed without reaching deeper merits because Miller did not do the litigation work required at summary judgment: when Defendants argued she lacked prima facie cases, she did not meaningfully respond. That omission activated Celotex Corp. v. Catrett and preservation doctrines (Jackson v. Genesee Cnty. Rd. Comm'n), allowing the court to resolve the appeal on failure-of-proof and forfeiture grounds.

On hostile environment, the court did reach the merits: most alleged mistreatment (training disputes, enforcement of instructions, coworker friction, alleged false complaints) was treated as workplace conflict not tied to race/sex/age/disability, and therefore excluded under Bowman v. Shawnee State Univ.. What remained—two early sexualized incidents and alleged disability-disparaging remarks—did not meet the Sixth Circuit’s “severe and pervasive” bar when compared to Nathan and Clark, and when filtered through Kellar’s caution that performance-related conversations, even if unpleasant, are typically not enough.

The court’s most explicitly doctrinal clarification addressed Muldrow. Miller argued that “some harm” replaced “severe or pervasive.” The panel rejected that reading, explaining (through McNeal and Kellar) that Muldrow removes any requirement of “significant” harm but does not dismantle the objective severe-or-pervasive analysis used to identify whether actionable harm occurred.

3.3 Impact

• Hostile environment litigation post-Muldrow (Sixth Circuit): This opinion underscores that plaintiffs should not treat Muldrow v. City of St. Louis as a doctrinal shortcut; hostile environment still requires objective and subjective severity/pervasiveness, with “some harm” functioning as a description of what that standard captures, not a replacement test.
• Federal-sector retaliation pleading and proof: Internal complaints must actually communicate a belief that unlawful discrimination occurred (not merely “harassment,” “bullying,” or “unfair treatment”) to qualify as protected opposition activity under Fox v. Eagle Distrib. Co..
• Rehabilitation Act strategy: Within the Sixth Circuit, retaliation claims should be pleaded under other available statutes where applicable, because § 504 retaliation is unavailable under Smith v. Mich. Dep't of Corr.—a holding this panel applied as dispositive.
• Summary-judgment practice: The case is a cautionary example that failing to address a prima facie argument at summary judgment can be fatal, and appellate briefing cannot revive forfeited theories. Practitioners should respond element-by-element and preserve alternative arguments (including comparator/replacement evidence and protected-activity specifics).
• Agency “acceptance” letters: The opinion signals that an agency’s preliminary decision to investigate (e.g., stating allegations “pass the severe or pervasive requirement for further processing”) is not an evidentiary admission of liability and may carry little weight once a final agency decision rejects the claim.

4. Complex Concepts Simplified

• “Prima facie case” (McDonnell Douglas): The initial checklist of facts a plaintiff must produce from which discrimination/retaliation can be inferred. If the plaintiff does not meet it, the court may end the analysis without considering the employer’s explanations.
• “Protected activity” (retaliation): Complaints or participation that relate to discrimination prohibited by the statute. General complaints about unfairness, personality conflicts, or being “picked on” are not enough unless tied to protected traits (race/sex/age/disability).
• “Severe or pervasive” harassment: A hostile-environment claim requires harassment that is serious (severe) or frequent/continuous (pervasive) enough that a reasonable person would find the workplace abusive—and the plaintiff actually perceived it that way.
• “Based on” a protected characteristic: Only conduct motivated by or tied to race/sex/age/disability counts in the hostile-environment analysis; generic workplace mistreatment does not.
• “Some harm” after Muldrow: Not a new, lower liability test for hostile environment in the Sixth Circuit; it means the plaintiff need not prove heightened or “significant” harm, but must still satisfy the objective severe-or-pervasive inquiry that identifies whether the workplace was made materially worse in its terms/conditions.
• “Schedule A” and probationary status (context, not dispositive here): “Schedule A” is a noncompetitive federal hiring authority for certain individuals with disabilities. A probationary period generally allows easier termination, but it does not eliminate anti-discrimination protections; it mainly affects the employment context and often the employer’s asserted legitimate reasons.

5. Conclusion

The Sixth Circuit’s decision affirming summary judgment against Miller is driven as much by procedural rigor as by substantive doctrine. The court enforced preservation rules (failure to respond to prima facie challenges and attempts to argue them first on appeal), applied a categorical bar to § 504 Rehabilitation Act retaliation under Smith v. Mich. Dep't of Corr., and reaffirmed that hostile-work-environment claims still require harassment that is “severe or pervasive” and “based on” a protected trait. Most notably, the panel clarified that Muldrow v. City of St. Louis does not dilute the severe-or-pervasive standard; it rejects only a heightened “significant harm” gloss, leaving the core Sixth Circuit framework intact.
