CHICAGO – Omni Hotels Management Corporation, an international hotel chain company headquartered in Dallas, violated federal law at its Michigan Avenue location in Chicago when it discriminated against an employee by denying his request to not work on Sundays due to his religion, the U.S. Equal Employment Opportunity Commission (EEOC) charged in a lawsuit filed today. The suit also alleged that Omni retaliated against the employee for requesting an accommodation by substantially reducing his hours.
