A new court decision could serve as a wake-up call to company owners and managers who impose dress codes on their workers: When it comes to religion, everything is different.

The ruling by U.S. District Judge Roslyn Silver concludes that Alamo Rent-A-Car violated federal law by refusing to allow a Muslim woman to wear a scarf during the holy month of Ramadan. The judge rejected a series of arguments by the company, including its contention that allowing her to wear the scarf — a clear sign of her religion in the wake of the 9/11 terrorist attacks — would cause the firm undue hardship.
