The Fair Labor Standards Act of 1938, as amended, is a Federal statute of general application which establishes minimum wage, maximum hours, overtime pay, equal pay, and child labor requirements that apply as provided in the Act. Employers and employees in enterprises in which retail sales of goods or services are made need to know how the Act applies to employment in these enterprises so that they may understand their rights and obligations under the law. All employees whose employment has the relationship to interstate or foreign commerce which the Act specifies are subject to the prescribed labor standards unless specifically exempted from them. Employers having such employees are required to comply with the Act's provisions in this regard 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.
