The purpose of the provisions set forth in Sec. 778.415 is to
provide an exception from the requirement of computing overtime pay at
not less than one and one-half times the regular rate for hours worked
in excess of the applicable maximum hours standard for a particular
workweek and to allow, under specified conditions, a simpler method of
computing overtime pay for employees paid on the basis of a piece rate,
or at a variety of hourly rates or piece rates, or a combination
thereof. This provision is not designed to exclude any group of
employees from the overtime benefits of the Act. The intent of the
provision is merely to simplify the method of computation while insuring
the receipt by the affected employees of substantially the same amount
of overtime compensation.
