Clarifying ADA Coverage: Temporary, Minor Illnesses and Reasonable Accommodation Obligations

Introduction

Paul Cook v. Warren Screw Products, Inc. is a Sixth Circuit decision issued on March 27, 2025. The plaintiff, Paul E. Cook, was hired as a delivery truck driver but missed two weeks of work after contracting what he described as a severe stomach bug. Upon his attempts to return, the employer, Warren Screw Products, asked for company property back and ultimately terminated his employment. Cook sued under the Americans with Disabilities Act (ADA), alleging disability discrimination and retaliation for seeking reasonable accommodation. The district court granted summary judgment for the employer, and Cook appealed. The central legal questions are:

Does a temporary stomach bug qualify as a “disability” under the ADA?
Did Warren Screw Products regard Cook as disabled?
Did Cook engage in protected activity by requesting medical leave or other accommodation?

Summary of the Judgment

The Sixth Circuit affirmed the district court’s grant of summary judgment. The court held:

No Actual Disability: Cook’s transient stomach bug did not substantially limit a major life activity (working or digestive functions) across a broad class of jobs, so he was not “actually disabled.”
No “Regarded-As” Disability: Under 42 U.S.C. § 12102(3)(B), the “transitory and minor” exception applies. A condition lasting under two weeks—and analogous to the common cold or flu—does not trigger ADA protection.
No Failure to Accommodate or Retaliation: Cook’s two weeks of leave requests (via doctor’s notes) did not constitute a reasonable accommodation request under the ADA, and he declined the employer’s reduced-hours offer. Because he did not make a good-faith request or engage in the interactive process, there was no protected activity and thus no retaliation.

Legal Reasoning

The court proceeded in two steps under the ADA:

Actual Disability Analysis: Under 42 U.S.C. § 12102(1)(A), the impairment must “substantially limit” a major life activity. The court emphasized that “substantial limitation” refers to an entire class or broad range of jobs. Cook’s stomach bug, lasting under two weeks and affecting only his ability to make deliveries that week, did not qualify.
“Regarded-As” Coverage: Under § 12102(1)(C), an employer’s erroneous belief about an impairment suffices unless the condition is “transitory and minor” (§ 12102(3)(B)). Cook’s stomach upset was both brief and analogous to common illnesses, so the exception applied.

On accommodation and retaliation, the court explained that an ADA claim requires:

An actual disability or perceived disability;
A request for reasonable accommodation or protected activity;
A material adverse employment action taken because of that request.

Cook’s doctor’s notes merely stated a return-to-work date without describing limitations or proposing specific accommodations. When Warren offered a part-time return, Cook refused. His failure to engage in the interactive process and lack of a concrete accommodation proposal meant no protected request and, therefore, no retaliation.

Impact

This decision clarifies and reinforces several key principles for both employers and employees:

Temporary, Minor Illnesses Excluded: Short-term conditions that mirror the common cold, flu, or stomach bug typically do not meet ADA disability definitions.
Transitory & Minor Exception: Employers may rely on § 12102(3)(B) to avoid “regarded-as” liability for brief ailments.
Broad Class of Jobs Standard: Plaintiffs must show that an impairment limits an entire job category or broad range of jobs—not just discrete tasks.
Interactive Process is Mandatory: Employees must propose specific accommodations and engage in good faith. Vague doctor’s notes without functional limitations are insufficient.
Documentation Matters: Clear, detailed medical documentation of limitations, and a concrete accommodation plan, are essential to establish a request.

Complex Concepts Simplified

Disability (ADA): A physical or mental impairment that substantially limits one or more major life activities; a record of such impairment; or being regarded as having such an impairment.
Major Life Activities: Functions such as working, eating, sleeping, walking, or bodily functions like digestion.
Actual vs. Regarded-As Disability: “Actual” requires real, substantial limitation; “regarded-as” requires employer’s erroneous belief about an impairment.
Transitory and Minor Exception: Conditions lasting six months or less and minor in severity fall outside “regarded-as” coverage.
Reasonable Accommodation: Changes or adjustments for a qualified individual with a disability; may include leave, modified tasks, or altered schedules.
Interactive Process: A two-way dialogue between employer and employee to identify workable accommodations.
Summary Judgment Standard: The court grants judgment if no genuine dispute of material fact exists and the moving party is entitled to judgment as a matter of law.

Conclusion

Paul Cook v. Warren Screw Products underscores the ADA’s clear boundary: not every temporary illness is a disability. By emphasizing the “broad class of jobs” test, the “transitory and minor” exception, and the necessity of detailed accommodation requests, the Sixth Circuit has provided a roadmap for employers and employees alike. Going forward, claimants with brief, self-limiting conditions must deliver robust medical documentation, articulate how a condition limits a major life activity, and fully engage in the interactive process. Employers, in turn, can rely on this decision to manage short-term absences without fear of ADA liability—so long as they treat genuine, substantial disabilities with the accommodations the law demands.
