A USPS letter carrier named Gerald Groff didn’t want to deliver Amazon packages on Sundays. His Sabbath observance conflicted with Sunday delivery shifts the Postal Service had taken on, and the agency offered him essentially nothing in the way of accommodation. The case ended up at the Supreme Court, and in June 2023 the Court issued a decision that quietly rewrote the rules for religious accommodation in every American workplace, including every federal agency in Dallas. A Dallas federal employee attorney who handles religious accommodation matters now has substantially stronger ground to stand on for federal workers whose requests have been brushed aside under the old framework that the Court replaced.
What Groff Changed
The case is Groff v. DeJoy, 600 U.S. 447 (2023). To understand what the Court did, you have to understand what it undid.
For nearly fifty years, federal courts had read Title VII’s religious accommodation provision through Trans World Airlines, Inc. v. Hardison, 432 U.S. 63 (1977). Hardison contained a phrase saying that an accommodation imposing more than a “de minimis” cost on the employer constituted an undue hardship. Lower courts had treated that phrase as a holding, and for decades agencies and private employers denied religious accommodations on the basis that they imposed any cost beyond trivial.
Groff held that Hardison’s de minimis language was never really the test. The actual standard, the Court clarified, requires an employer to show that the burden of granting an accommodation would result in “substantial increased costs in relation to the conduct of its particular business.” Substantial increased costs. Not trivial costs. Not theoretical costs. Substantial costs measured against the employer’s overall operations.
The Court also clarified that the analysis is fact-specific. Generic concerns about coworker resentment, scheduling inconvenience, or administrative burden don’t satisfy the standard. The agency has to prove specific, substantial, real-world costs.
How the Standard Applies in the Federal Sector
Title VII covers federal employees through 42 U.S.C. § 2000e-16, with religious accommodation requirements imposed by the same statute and the same EEOC regulations that apply to private-sector employers. Groff applies fully to federal agencies.
The EEOC issued updated guidance in early 2024 incorporating Groff into its religious accommodation framework, and the Office of Federal Operations has begun applying the new standard in federal sector decisions. Agencies that denied accommodation requests under the old de minimis framework are now finding those denials harder to defend.
Common federal-sector religious accommodation issues include:
- Sabbath and holy day observance requiring schedule modifications
- Religious dress and grooming standards (head coverings, beards, religious jewelry)
- Prayer time during the workday
- Dietary observance affecting agency events
- Refusal to participate in specific job functions on religious grounds
- Religious objections to specific training programs or required activities
- Pilgrimage leave for religious obligations
After Groff, an agency that denies any of these requests has to articulate a substantial cost connected to the agency’s actual operations, not a generalized concern about precedent or coworker reaction.
What Counts as a Sincere Religious Belief
The first issue in any religious accommodation case is whether the employee’s belief is religious and sincerely held. Title VII’s protection is broad: it covers traditional theistic religions, non-theistic moral or ethical beliefs held with the strength of religious conviction, and beliefs not necessarily shared by others within the employee’s denomination.
The agency cannot second-guess the religious nature of a belief. Even unusual or recently adopted beliefs are protected if sincerely held. The sincerity inquiry is appropriate but limited; agencies can consider whether the employee’s actions are consistent with the claimed belief, but they cannot demand affidavits from clergy or impose theological tests.
The most common factual disputes involve sincerity rather than religiosity. An employee who routinely worked Sundays for years and then suddenly invokes Sabbath observance after a scheduling change may face questions, but those questions go to credibility, not the existence of the protection.
How to Make a Religious Accommodation Request
A request can be oral or written, although written is strongly preferable. The employee doesn’t have to use the words “religious accommodation” or cite Title VII. Telling a supervisor “I can’t work Saturdays because of my Sabbath” or “I need to keep my beard for religious reasons” puts the agency on notice.
Once a request is made, the agency must engage in the interactive process: a flexible, two-way exchange to identify the employee’s needs and possible accommodations. The agency can request enough information to verify the religious nature of the belief and the connection to the requested accommodation, but it cannot demand more than that.
After Groff, the interactive process matters more than ever. Agencies that go through the motions and deny accommodations without exploring alternatives are vulnerable to challenge in ways they weren’t before.
Common Accommodations and Agency Responses
A few practical examples of how the post-Groff analysis plays out in federal contexts:
Schedule modifications. An agency facing a Sabbath request can no longer deny it solely because it would require asking other employees to cover shifts or paying overtime for someone else’s coverage. The agency has to show that those costs are substantial in relation to its operations.
Religious dress and grooming. Beard-length policies, head-covering restrictions, and uniform requirements that conflict with religious practice now require specific justification tied to safety, security, or operational necessity, not generalized appearance standards.
Prayer time. Federal agencies have generally been required to allow brief prayer breaks where they don’t disrupt operations. Groff strengthens that position.
Specific task objections. Where an employee has a religious objection to performing a particular task, the agency must consider reassignment of that task to others, schedule adjustments, or transfer to a position without the conflicting duty before denying accommodation.
When a Request Is Denied
When an agency formally denies a religious accommodation, the federal sector EEO process is the enforcement path. The employee has 45 calendar days from the denial (or from a continuing failure to accommodate) to contact an EEO counselor at the agency. The same 45-day rule that catches federal workers off guard in other contexts applies here.
After timely contact, the case proceeds through informal counseling, formal complaint, agency investigation, and the choice between an EEOC administrative judge hearing at the Dallas District Office or a final agency decision. The Groff standard applies throughout.
A few practical steps before filing anything:
Document the request, the agency’s response, and the timeline. Religious accommodation cases benefit from a clear record of what was asked, what was offered, and what was rejected.
Identify any comparators. If similarly situated employees received scheduling flexibility, dress accommodations, or other arrangements for non-religious reasons, that comparison strengthens the case.
Preserve evidence of the agency’s articulated reasons for denial. Generic claims of “operational concerns” without specific cost analysis are now weaker than they were pre-Groff.
Avoid signing any settlement or agreement without counsel review.
Federal employees in DFW facing religious accommodation issues across the FAA Southwest Region, the VA North Texas Health Care System, IRS facilities, USPS distribution centers, the FBI Dallas Field Office, SSA hearing offices, HUD Region VI, ICE/HSI, CBP at DFW, the Federal Reserve Bank of Dallas, and other agencies all operate under the same post-Groff framework.
For background, eeoc.gov/religious-discrimination, the EEOC’s updated Section 12 of the Compliance Manual, and the OFO’s religious accommodation decisions are reliable resources.
Talk to a Dallas Federal Employee Attorney Who Knows the Post-Groff Framework
Religious accommodation cases that would have lost under the old de minimis standard are winnable now. A Dallas federal employee attorney who has tracked the post-Groff guidance and the federal-sector decisions applying it can help a federal worker frame a request, respond to a denial, or build a case that takes advantage of the changed legal landscape. If your accommodation request has been denied, ignored, or met with retaliation, contact counsel before the 45-day window closes.
