Earlier this month, the Justice Department's Office of Legal Counsel (OLC) issued an advisory opinion Religious Liberty Protections for Federal Employees in Light of Recent Legal Developments, 49 Op. O.L.C. __ (Sept. 18, 2025). The opinion was requested by the Acting Chair of the U.S. Equal Employment Opportunity Commission who wanted to know the extent to which 1997 Guidelines on Religious Exercise and Religious Expression in the Federal Workplace and a 2017 Memorandum Federal Law Protections for Religious Liberty remain operative. OLC responded that recent developments require two exceptions to continuing to enforce those prior directives:
First ... the Supreme Court held in Groff that an employer experiences “undue hardship” only where the burden posed by an accommodation would be “substantial in the overall context of an employer’s business.”... Thus, under Title VII, an agency cannot deny a religious accommodation if the burden imposed on the agency by the accommodation in the context of the agency’s work is insubstantial. Agencies should therefore disregard references in the 1997 Guidelines to the “de minimis” standard as inconsistent with their statutory obligations....
Second, the 1997 Guidelines provide that, although agencies generally may not “restrict personal religious expression by employees in the Federal workplace,” agencies must restrict such expression where it “creates the appearance, to a reasonable observer, of an official endorsement of religion.”... Again, that restriction reflected Supreme Court precedent that has since been abrogated....
The 1997 Guidelines’ “official endorsement” test thus creates a special restriction on religious expression without a constitutionally valid justification.
... [O]ur conclusion that the “appearance of official endorsement” test can no longer be enforced does not mean that all religious expression in the workplace must be permitted. Nor does it mean that the Constitution imposes no limits on religious conduct or expression by government employees. The Supreme Court has never cast doubt on the principle that government employers can prohibit disruptive or coercive behavior by their employees regardless of the religious nature of that conduct.
The OLC Opinion also went on to provide that telework as a form of religious accommodation for federal employees may still be used despite President Trump's directive to federal employees to return to in-person work.
