The Supreme Court sided with Trans World Airlines, stating that the Equal Employment Opportunity Commission requires "reasonable" accommodations for religious exercise.

[1][2] Justice Thurgood Marshall, in a widely-cited dissent, wrote, "[O]ne of this Nation's pillars of strength, our hospitality to religious diversity, has been seriously eroded.

Justice Alito, joined by Justices Thomas and Gorsuch, wrote a statement calling for the Hardison precedent to be reconsidered in a future appropriate case: I agree with the most important point made in that brief, namely, that we should reconsider the proposition, endorsed by the opinion in Trans World Airlines, Inc. v. Hardison, 432 U. S. 63, 84 (1977), that Title VII does not require an employer to make any accommodation for an employee's practice of religion if doing so would impose more than a de minimis burden.

[3]Similarly, in 2021, the Supreme Court denied certiorari in Dalberiste v. GLE Associates and Small v. Memphis Light, Gas & Water, cases that potentially challenged the established precedent.

[4][5] On September 26, 2022, 15 members of the US Congress filed an amicus brief arguing that the standard in Hardison for "undue hardship" conflicted with the text and legislative purpose of Title VII.
