The payroll records of Mortimer Inc. revealed that all the employees worked an average of 48 hours in the month of June. Each worker received $7.20 an hour for the first 40 hours per week and $10.80 for the eight hours overtime. In May, some employees had been paid as much as $8.00 per hour for the first 40 hours, but the company reduced the scale when female employees complained that men were being paid more for the same work. The records also revealed that the plant manager and personnel manager worked as many as 60 hours per week but did not receive overtime pay. Discuss any legal problems that may exist in this scenario.
