The Wage and Hour Division (WHD) of the United States Department of Labor is responsible for enforcing federal labor laws related to the minimum wage, overtime pay, recordkeeping, and child labor. The WHD was created in the 1930s as part of the Fair Labor Standards Act (FLSA), which established the national minimum wage and established the 40-hour workweek. The WHD is responsible for investigating complaints and conducting audits to ensure that employers are complying with the FLSA and other labor laws. The WHD also provides information and assistance to workers and employers to help them understand their rights and responsibilities under the law.
