Final answer:
The McNamara-O'Hara Service Contract Act requires contractors and subcontractors on federal service contracts to pay service workers prevailing wage rates and fringe benefits as determined by the Department of Labor, protecting workers' rights and the procurement process.
Step-by-step explanation:
The McNamara-O'Hara Service Contract Act (SCA) covers contracts entered into by federal and District of Columbia agencies where the principal purpose is to furnish services in the United States through the use of service employees. Specifically, the Act ensures that employees working on federal service contracts receive fair and equitable wages and benefits. It requires contractors and subcontractors performing services to pay their service workers no less than the wage rates and fringe benefits found prevailing in the locality, or the rates (including prospective increases) contained in a predecessor contractor's collective bargaining agreement. The Department of Labor determines these rates. The Act is designed to protect both the workers and the integrity of the procurement process.
