When the commission is paid on a weekly basis, it is added to the
employee's other earnings for that workweek (except overtime premiums
and other payments excluded as provided in section 7(e) of the Act), and
the total is divided by the total number of hours worked in the workweek
to obtain the employee's regular hourly rate for the particular
workweek. The employee must then be paid extra compensation at one-half
of that rate for each hour worked in excess of the applicable maximum
hours standard.
