On June 29, 2023, the Supreme Court of the United States issued three opinions. Of them, Groff v. DeJoy (“Groff”),in which the Court unanimously revised the standard for determining whether accommodating an employee’s religious beliefs would constitute an “undue hardship” under Title VII of the Civil Rights Act of 1964 (“Title VII”), will have the most immediate impact on employers. In Groff, the Court held that employers cannot deny a religious accommodation by demonstrating that it would result in only more than a de minimis cost, but rather must demonstrate that it would result in a substantial cost.
