29 CFR 1620.9 - Meaning of “establishment.”
(a) Although not expressly defined in the FLSA, the term “establishment” had acquired a well settled meaning by the time of enactment of the Equal Pay Act. It refers to a distinct physical place of business rather than to an entire business or “enterprise” which may include several separate places of business. Accordingly, each physically separate place of business is ordinarily considered a separate establishment.
(b) In unusual circumstances, two or more portions of a business enterprise, even though located in a single physical place of business, may constitute more than one establishment. For example, the facts might reveal that these portions of the enterprise are physically segregated, engaged in functionally separate operations, and have separate employees and maintain separate records. Conversely, unusual circumstances may call for two or more distinct physical portions of a business enterprise being treated as a single establishment. For example, a central administrative unit may hire all employees, set wages, and assign the location of employment; employees may frequently interchange work locations; and daily duties may be virtually identical and performed under similar working conditions. Barring unusual circumstances, however, the term “establishment” will be applied as described in paragraph (a) of this section.
