29 C.F.R. § 779.106 Employees employed by an independent employer.
Title 29 - Labor
Where the work of an employee would be closely related and directly essential to the production of goods for commerce if he were employed by a producer of the goods, the mere fact that the employee is employed by an independent employer will not justify a different answer. (See §§776.17(c) and 776.19 of this chapter.)
