What the US religious accommodation ruling means for employers

The US Supreme Court’s decision in Groff v DeJoy has sharpened the rules around religious accommodation at work. The ruling concerns an American postal worker who objected to Sunday shifts, but its practical message reaches any employer managing rosters, religious observance and competing workplace needs.

For Australian businesses, the decision is not binding law. It does, however, offer a useful benchmark for thinking about genuine religious accommodation, fair scheduling and the point at which an adjustment becomes unreasonable. That matters in workplaces from Sydney offices and Melbourne hospitals to hospitality venues, warehouses and FIFO mining operations.

The ruling in plain English

The Supreme Court held that an employer cannot refuse a religious accommodation simply because it creates a minor inconvenience. Under Title VII of the US Civil Rights Act, an employer must accommodate an employee’s religious practice unless doing so would create a “substantial increased cost” in relation to the conduct of the business.

The decision rejected the looser idea that an employer could refuse an accommodation whenever it caused anything more than a minimal burden. In practice, employers need to examine the real operational impact rather than rely on a general statement that changing a roster would be difficult.

What changed under US employment law

The case involved Sunday work and the effect of repeated schedule changes on colleagues. The Court said impacts on other workers can be relevant, but only when they affect the business’s operations. Mere resentment, inconvenience or hostility from colleagues is not enough by itself.

The decision also does not give employees an automatic right to every preferred arrangement. Employers may consider seniority systems, collective agreements, staffing levels, customer commitments and safety requirements. The central obligation is to assess reasonable alternatives in good faith before rejecting a request.

Why rosters and holidays matter

Religious accommodation often arises through ordinary scheduling decisions. An employee may request time away for Friday prayers, Sabbath observance, Eid, Diwali, Yom Kippur, Orthodox Easter or another significant day. The same issue can arise with uniforms, grooming rules, prayer breaks, fasting and workplace food arrangements.

Australian employers already manage complex holiday calendars. Public holidays such as Anzac Day, Good Friday and Australia Day affect staffing, while multicultural teams may observe religious dates that are not public holidays. Sunday penalty rates, award obligations and casual staffing models can make roster changes particularly sensitive in retail, healthcare, transport and hospitality.

The Australian legal backdrop

The US ruling does not create a new right in Australia. Australian employers must instead consider the Fair Work Act 2009, federal discrimination protections and applicable state or territory laws. Section 351 of the Fair Work Act restricts adverse action because of attributes including religion, subject to specific exceptions such as inherent job requirements and the operation of other anti-discrimination laws.

There is no single Australian equivalent to the US Title VII accommodation test. Protection can vary between jurisdictions, including under laws applying in New South Wales, Victoria, Queensland and other states and territories. Employers should also check modern awards, enterprise agreements, employment contracts and workplace policies before changing a roster or declining a request.

Practical lessons for Australian businesses

A strong process begins with a respectful, specific conversation. The employer should understand what religious practice is involved, what adjustment is requested and whether the request is temporary, recurring or linked to particular dates. Employees should not be forced to disclose more personal information than is reasonably necessary.

Possible options might include a shift swap, adjusted start and finish times, annual leave, remote work where suitable, a different uniform arrangement or a short unpaid break. In a Melbourne café, that could mean planning around Friday prayers; in a Queensland warehouse, it might involve advance notice for Eid; in a Perth mining operation, accommodation may need to fit strict transport and safety systems.

Assessing operational impact fairly

An employer should document the actual effect of each option. Relevant factors can include additional labour costs, overtime, fatigue risks, mandatory qualifications, patient or customer coverage, production deadlines and the availability of replacement staff. A vague reference to “team disruption” is weaker than evidence showing why a particular arrangement would compromise safe or lawful operations.

The business should also consider whether the burden can be shared fairly. Repeatedly assigning unpopular shifts to the same employees may create a separate workplace issue, while automatically refusing every religious request can expose the employer to discrimination claims. Clear rostering rules, advance planning and consistent treatment help balance individual observance with operational needs.

Where accommodation has limits

Accommodation does not require an employer to remove an essential job function or disregard genuine safety requirements. A hospital may need qualified staff on a particular shift, an airline must comply with aviation rules, and a mine may have fixed transport and emergency procedures. In those settings, alternative adjustments may be more realistic than removing an employee from a required roster.

Employee preferences and religious beliefs should still be treated seriously. Employers should avoid assumptions about how observant a person is, whether a practice is mandatory or whether a particular faith has a single view. The relevant question is usually whether a reasonable adjustment can be made without imposing an excessive burden on the business.

Building a defensible workplace process

Policies should explain how employees can request religious adjustments, who will assess them and how privacy will be protected. Managers need training so that a request is not dismissed as inconvenient, political or incompatible with the team’s culture. Written reasons are especially important when an accommodation is refused.

Australian businesses can use the Groff decision as a prompt to review rostering, leave, uniform, break and workplace conduct policies. It is not a substitute for Australian legal advice, but it reinforces a sound principle: investigate the request, test practical alternatives and base the final decision on evidence.

Review your workplace policies and roster practices now, especially before major religious festivals and peak trading periods. A documented, respectful accommodation process can help Australian employers support a diverse workforce while protecting safety, service standards and legal compliance.
