Housekeeping is one of the departments in the hotel that must work every holiday because the hotel is open and often very busy. Assume you have a housekeeping department with 24 employees and your hotel recognizes New Year’s Day, Memorial Day, Fourth of July, Labor Day, Thanksgiving, and Christmas as paid holidays. Also assume that at least one-quarter (6) of your housekeeping employees need to work each holiday to clean the stay-over rooms. Design a scheduling system that fairly assigns these holidays to the employees. What factors would you take into consideration in developing the scheduling system?
