Section 13(b)(15) of the Fair Labor Standards Act exempts from the
overtime requirements of section 7:
Any employee engaged in ginning of cotton for market, in any place
of employment located in a county where cotton is grown in commercial
quantities, or in the processing of sugar beets, sugar-beet molasses,
sugarcane, or maple sap, into sugar (other than refined sugar) or syrup.
Section 13(b)(15) supplants two exemptions that were contained in the
Act prior to the Fair Labor Standards Amendments of 1966. The first is
former section 13(a)(18), having identical language, which provided a
complete exemption for those employed in the ginning of cotton. The
second is the former section 7(c) which provided an overtime exemption
for the employees of an employer engaged in sugar processing operations
resulting in unrefined sugar or syrup.
