Where an employee in a single workweek works at two or more
different types of work for which different nonovertime rates of pay (of
not less than the applicable minimum wage) have been established, his
regular rate for
that week is the weighted average of such rates. That is, his total
earnings (except statutory exclusions) are computed to include his
compensation during the workweek from all such rates, and are then
divided by the total number of hours worked at all jobs. Certain
statutory exceptions permitting alternative methods of computing
overtime pay in such cases are discussed in Secs. 778.400 and 778.415
through 778.421.
