Fact Sheet 17P: Construction Workers and the Part 541 Exemptions under the Fair Labor Standards Act (FLSA)
The FLSA requires that most employees in the United States be paid at least the federal minimum wage for all hour worked and overtime pay at time and one-half the regular rate of pay for all hours worked over 40 in a workweek. However, Section 13(a)(1) of the FLSA provides an exemption from both minimum wage and overtime pay for employees employed as bona fide executive, administrative, professional and outside sales employees. Section 13(a)(1) and Section 13(a)(17) also exempts certain computer employees. To qualify for exemption, employees must meet certain tests regarding their job duties and be paid on a salary basis at not less than $455 per week.
