Congress made no change in section 12 as regards domestic service
employees. Accordingly, the child labor provisions of the Act do not
apply unless the underaged minor (a) is individually engaged in commerce
or in the production of goods for commerce, or (b) is employed by an
enterprise meeting the coverage tests of sections 3(r) and 3(s)(1) of
the Act, or (c) is employed in or about a home where work in the
production of goods for commerce is performed.
