29 CFR § 778.419 - Hourly workers employed at two or more jobs.
(a) Under section 7(g)(2) an employee who performs two or more different kinds of work, for which different straight time hourly rates are established, may agree with his employer in advance of the performance of the work that he will be paid during overtime hours at a rate not less than one and one-half times the hourly nonovertime rate established for the type of work he is performing during such overtime hours. No additional overtime pay will be due under the act provided that the general requirements set forth in § 778.417 are met and;
(1) The hourly rate upon which the overtime rate is based in a bona fide rate;
(2) The overtime hours for which the overtime rate is paid qualify as overtime hours under section 7(e) (5), (6), or (7); and
(3) The number of overtime hours for which the overtime rate is paid equals or exceeds the number of hours worked in excess of the applicable maximum hours standard.
(b) An hourly rate will be regarded as a bona fide rate for a particular kind of work it is equal to or greater than the applicable minimum rate therefor and if it is the rate actually paid for such work when performed during nonovertime hours.
