The activities constituting ``production'' within the meaning of the
phrase ``engaged in * * * the production of goods for commerce'' are
defined in section 3(j) of the Act. (The statutory definition is set
forth in Sec. 779.13.) The handling or otherwise working on goods
intended for shipment out of the State, directly or indirectly, in
engagement in the ``production'' of goods for commerce. Thus, employees
in retail stores who sell, pack, or otherwise work on goods which are to
be shipped or delivered outside of the State are engaged in the
production of goods for commerce. Typically, but not exclusively,
employees engaged in the production of goods for interstate or foreign
commerce, include those who work in manufacturing, processing and
distributing establishments, including wholesale or retail
establishments, that produce goods for interstate or foreign commerce.
This includes everyone, including office, management, sales and shipping
personnel, and maintenance, custodial and protective employees, whether
they are employed by the producer or an intermediary. Employees may be
covered even if their employer does not ship his goods directly in such
commerce. The goods may leave the State through another firm. The
workers may produce goods which become a part or ingredient of goods
shipped in interstate or foreign commerce by another firm. Also covered
are workers who are engaged in a closely related process or occupation
directly essential to such production. (See Sec. 779.105.)
