Post Office The Post Office wants to establish a weekly schedule that can be reused for the future. The Post Office hires both full-time and part-time employees that work 5-day shifts. In other words, if an employee starts on Monday, his or her shift will end on Friday. Likewise, if an employee starts on Wednesday, then his or her shift will end on Sunday. Suppose that each fill-time employee work eight hours per day and part-time employees work four hours per day. The Post Office has determined the number of hours per day that they will need to meet in order to meet their performance goals
