Yes. According to Title VII of the Civil Rights Act, upon request, employers must provide “reasonable accommodation” to employees. A 2015 Supreme Court decision, EEOC v. Abercrombie & Fitch Stores, held that employers could unintentionally discriminate if they suspect an employee holds religious views but do not accommodate them – even if the employee did not request the accommodation. In that case, the company illegally discriminated against a prospective employee by denying her a job because her hijab violated the company’s dress code at the time.
