The overtime compensation due employees of a retail or service
establishment who do not meet the exemption requirements of section 7(i)
may be computed under the provisions of section 7(g)(3) of the Act if
the employer and employee agree to do so under the conditions there
provided. Section 7(g)(3) permits the use of a basic rate established,
pursuant to agreement or understanding in advance of the work, in lieu
of the regular rate for the purpose of computing overtime compensation.
The use of such a basic rate for employees of a retail or service
establishment compensated wholly or partly by commissions is authorized
under the conditions set forth in part 548 of this chapter.
