On Friday, the Supreme Court took up a case that could grant special privileges to religious employees at the expense of their coworkers; it would also legalize discrimination within the workplace. Groff v. DeJoy is a frightening case because this court, and much of the federal judiciary, simply cannot be trusted to adjudicate sensitive disputes about religious accommodations on the job. The current state of the law is biased against religious minorities with legitimate claims of mistreatment, especially Muslims and Sikhs. But the remedy may be worse, favoring conservative Christians who wish to discriminate against colleagues and customers. Groff shows what we lose when we cannot rely on the Supreme Court to handle difficult matters of faith without favoritism toward one particular vision of Christianity.

It was only a matter of time before SCOTUS heard a case like Groff. The plaintiff, Gerald Groff, is a postal carrier whose religion requires him to observe the Sabbath every Sunday. After USPS ordered him to deliver packages on Sundays, he resigned and sued under Title VII of the Civil Rights Act of 1964. That law bars employment discrimination “because of religion” and directs employers to “reasonably accommodate” workers’ religious observance. It adds, however, that employers can refuse to provide accommodations that would place “undue hardship on the conduct of the employer’s business.” Groff lost in the lower courts.
