There are many instances where several establishments, persons,
corporations, or other business organizations, join together to perform
some or all of their activities as a unified business or business
system. They may accomplish such unification through agreements,
franchises, grants, leases, or other arrangements which have the effect
of aligning or integrating the activities of one company with the
activities of others so that they constitute a single business or
unified business system. Whether in any particular case the activities
are performed through ``unified operation'' and have the effect of
creating a single enterprise, will depend upon all the facts, including
the manner in which the activities are performed, the agreements and
arrangements which govern their performance,
and the other relationships between the parties, considered in the light
of the statutory provision and the legislative intent. (cf Wirtz v.
Wornom's Pharmacy (E.D. Va.), 18 WH Cases 289, 365; 57 Labor Cases
32,006, 32,030.)
