Under the definition, the ``enterprise'' consists of ``the related
activities performed * * * for a common business purpose.'' All of the
activities comprising the enterprise must be ``related.'' Activities
serving a single business purpose may be related, although different,
but other activities which are not related are not included in the
enterprise. The definition makes clear that the enterprise includes all
such related activities which are performed through ``unified
operation'' or ``common control.'' This is true even if they are
performed by more than one person, or in more than one establishment, or
by more than one corporate or other organizational unit. Specifically
included, as a part of the enterprise, are departments of an
establishment operated through leasing arrangements. On the other hand,
the definition excludes from the ``enterprise'' activities only
performed ``for'' the enterprise rather than as a part of it by an
independent contractor even if they are related to the activities of the
enterprise. Also, it makes clear that a truly independent retail or
service establishment does not become a part of a larger enterprise
merely because it enters into certain types of franchise or collective
purchasing arrangements or because it has a common landlord with other
such retail establishments.
