Steven Goldberg, who is Jewish, is a factory worker at Uranus Umbrella Company. His work shift has been changed on weekdays to 11:00 a.m. to 7:00 p.m. He asks for an accommodation to have his shift adjusted on Fridays to allow him to return home before sunset. Uranus claims this accommodation would place it in violation of the seniority provision of the collective bargaining agreement it has with Steven's union. How would you advise Uranus?
