29 C.F.R. § 780.1

The Fair Labor Standards Act is a Federal statute of general application which establishes minimum wage, overtime pay, equal pay, and child labor requirements that apply as provided in the Act. These requirements are applicable, except where exemptions are provided, to employees in those workweeks when they are engaged in interstate or foreign commerce or in the production of goods for such commerce or are employed in enterprises so engaged within the meaning of definitions set forth in the Act. Employers having such employees are required to comply with the Act's provisions in this regard unless relieved therefrom by some exemption in the Act, and with specified recordkeeping requirements contained in part 516 of this chapter. The law authorizes the Department of Labor to investigate for compliance and, in the event of violations, to supervise the payment of unpaid minimum wages or unpaid overtime compensation owing to any employee. The law also provides for enforcement in the courts.
