Section 12(c) was amended in 1961 to prohibit the employment of
oppressive child labor in any enterprise engaged in commerce or in the
production of goods for commerce. Thus, employers in every enterprise
which is covered under the Act must comply with section 12(c) of the
child labor provisions of the Act. As stated in Sec. 779.503, compliance
with this provision is necessary even though the employers in a
particular establishment or establishments of a covered enterprise are
exempt from the requirement of compensating employees in accordance with
sections 6 and 7 of the Act.
