US Airways, Inc. v. Barnett, (2002), was a case in the United States Supreme Court that dealt with issues related to the Americans with Disabilities Act of 1990 (ADA) and reasonable accommodations in the workplace.

[1][2] The Court held that even requests for accommodation that might seem reasonable on their face, such as a transfer to a different position, can be rendered unreasonable if they would require a violation of the company's seniority system.

[4] The court also held that the defendant need not provide proof that this particular application of the seniority system should prevail, and that, once the defendant showed that the accommodation violated the seniority system, it fell to the plaintiff (Barnett) to show it was nevertheless reasonable.

[3] The case involved Robert Barnett, a US Airways employee who injured his back, rendering him physically unable to perform his cargo-handling job.

[1] This case clarified the standards surrounding reasonable accommodations under the ADA and emphasized the importance of considering the impact of seniority systems in employment decisions.
