CREDIT HOUR PROGRAM. Section 1. Credit hours means any hours, within a flexible work schedule, which are in excess of an employee’s basic work requirement (the number of hours he is required to work or account for by leave or otherwise), and which the employee elects to work so as to vary the length of a workweek or a workday. Any work elected as credit-hour work shall first be approved by the supervisor. Employees on CWS are not eligible for credit hours.
