Example. An employee who is paid on a weekly basis with overtime after 40 hours works six 8-hour days in a workweek under an agreement or understanding reached pursuant to this subsection. He performs three different types of piecework, each at a different rate of pay. The basic rates to be used for computing overtime in this situation would be arrived at by dividing the earnings for each type of work by the number of hours during which that type of work was performed. There would thus be three different basic rates, one for each type of work. Since the overtime hours used in this illustration occur on the sixth day, the types of work performed on the sixth day would determine the basic rate or rates on which overtime would be computed that week. Thus, if the average hourly earnings for the three types of work are respectively $1.70 an hour in type A, $1.80 an hour in type B, and $2 an hour in type C, and on the sixth day the employee works on type B, his overtime premium for the sixth day would be one-half the basic rate of $1.80 an hour, multiplied by the 8 hours worked on that day.
