R 408.723 Computing regular rate of pay for overtime compensation.

Rule 23. (1) If an employee is paid on an hourly rate plus commission or salary plus commission, then the salary and commission shall be considered as gross earnings for the workweek, and the regular rate is obtained by dividing the sum by the number of hours for which the salary was paid. (2) If an employee is paid on a piece-rate basis, then the regular rate of pay is computed by adding together the total earnings of the workweek from piece rates and all other earnings and any sums paid for other hours worked. This sum total is divided by the number of hours worked in that week to yield the pieceworker's regular rate for that week.
