In determining the number of hours for which overtime compensation
is due, all hours worked (see Sec. 778.223) by an employee for an
employer in a particular workweek must be counted. Overtime
compensation, at a rate not less than one and one-half times the regular
rate of pay, must be paid for each hour worked in the workweek in excess
of the applicable maximum hours standard. This extra compensation for
the excess hours of overtime work under the Act cannot be said to have
been paid to an employee unless all the straight time compensation due
him for the nonovertime hours under his contract (express or implied) or
under any applicable statute has been paid.
