Gil Bates, a computer analyst and programmer of Hard Drive Company, works eight hours a day for five days a week at the main office providing customers information technology assistance. On Saturdays, however, the company requires him to keep his cellular phone open from 8:00 A.M. to 5:00 P.M. so that the Management could contact him in case of heavy workload or emergency problems needing his expertise. May said hours on Saturdays be considered compensable working hours "while on call"? If so, should said compensation be reported to the Social Security System? (2004 BAR)
