Robert Barnett worked as a cargo handler for US Airways, a physically demanding job. After suffering a back injury that limited his ability to lift and handle cargo, he transferred to a less strenuous mailroom position. US Airways maintained a formal seniority system that governed employee bidding and displacement rights for positions. Shortly after Barnett moved to the mailroom, the position was opened to seniority-based bidding pursuant to the company's system, and two more senior employees sought the job. Anticipating displacement, Barnett asked US Airways to allow him to remain in the mailroom as a reasonable accommodation under the ADA. The company declined, citing its seniority rules. Barnett was displaced by the senior bidders, could not return to the cargo job because of his physical restrictions, and ultimately lost his employment. He sued under the ADA, claiming that reassignment by exception to the seniority system was a reasonable accommodation. The district court granted summary judgment to US Airways. The Ninth Circuit reversed, reasoning that violating a seniority system was not per se unreasonable and that reasonableness should go to a jury. The Supreme Court granted certiorari.
Does the ADA require an employer to make an exception to a bona fide seniority system as a reasonable accommodation for a disabled employee seeking reassignment to a position he can perform?
Under the ADA, a requested accommodation that conflicts with the rules of a bona fide seniority system is ordinarily not a reasonable accommodation. The employer's showing of such a conflict typically suffices to defeat reasonableness. However, the employee may demonstrate special circumstances that make an exception to the seniority system reasonable in the particular case (e.g., where the system is not consistently applied, frequently excepted, or otherwise fails to create strong employee reliance interests). The burden proceeds as follows: (1) the employee must show that the accommodation (such as reassignment to a vacant position) is facially reasonable; (2) the employer may then show that the accommodation would violate a seniority system; and (3) the employee may attempt to show special circumstances making the accommodation reasonable notwithstanding the seniority conflict. An employer need not separately prove undue hardship once it has shown the seniority-system conflict renders the accommodation ordinarily unreasonable.
No. The ADA does not require an employer to violate a bona fide seniority system to accommodate a disabled employee in the run of cases. A conflict with such a system ordinarily renders the accommodation unreasonable, though an employee can attempt to show special circumstances making an exception reasonable. The Court vacated the Ninth Circuit's judgment and remanded for application of this standard.
The Court began by acknowledging that the ADA sometimes requires preferential treatment—accommodations that give a qualified employee with a disability access to work opportunities otherwise unavailable. Reassignment to a vacant position is an example of a facially reasonable accommodation recognized by the statute and EEOC regulations. But reasonableness is not absolute; it is context-dependent and considers the costs, disruptions, and legitimate expectations in the workplace. Seniority systems—whether collectively bargained or unilaterally imposed—allocate job rights and opportunities according to tenure, engendering employee expectations and reliance interests that promote job security and predictability. Requiring an employer to override those settled expectations by exception in favor of a later-hired or less senior worker will typically impose significant costs and undermine the system's integrity. Because of these systemic and reliance-based concerns, a requested accommodation that would violate a bona fide seniority system is ordinarily not reasonable. This conclusion flows from the structure of the ADA: the reasonableness inquiry is distinct from undue hardship, and certain conflicts—here, with a seniority system—can short-circuit the reasonableness of a proposed accommodation without requiring the employer to prove hardship. At the same time, the Court rejected a per se rule. Seniority systems vary in rigidity and application. If the employee can show special circumstances indicating that the system does not create strong, settled expectations—such as frequent exceptions, employer discretion to deviate at will, inconsistent application, or evidence that the particular requested exception would not disrupt coworker expectations—then the accommodation may still be reasonable in the specific case. Thus, the Court set a burden-shifting framework: an employee makes a facial showing of reasonableness (e.g., reassignment to a vacant position); the employer shows conflict with a seniority system; the employee may then rebut by demonstrating special circumstances. Because the lower courts did not apply this standard, remand was required.
Barnett is essential for understanding the ADA's reasonable accommodation doctrine, especially the limits of reassignment. It establishes that seniority systems generally trump accommodation requests but preserves a fact-intensive pathway for employees to show that an exception is still reasonable. The case offers a practical, exam-ready burden-shifting approach and highlights the importance of evidence about how a seniority system actually operates. For employers, it underscores documenting and consistently applying seniority rules; for employees, it emphasizes building a record of special circumstances—such as prior exceptions—that diminish coworker reliance and support reasonableness.
US Airways v. Barnett articulates a pragmatic standard at the intersection of disability rights and workplace ordering. By recognizing that the ADA sometimes mandates preferences while also safeguarding the reliance interests embedded in seniority systems, the Court sets a workable presumption that respects both statutory purpose and labor-management realities.
