Title VII requires an employer that denies a religious accommodation to show that the burden of granting an accommodation would result in substantial increased costs in relation to the conduct of its particular business. Groff v. DeJoy (US Supreme Ct 06/29/2023) [PDF].

This "clarification" of Trans World Airlines, Inc. v. Hardison, 432 U. S. 63 (1977) will be a game-changer for determining whether an employer must accommodate an employee's religious beliefs and practices. Employers must now consider forcing other employees to work overtime, voluntary shift swapping, and other options.
