The U.S. Department of Labor (DOL) is a federal agency responsible for promoting and ensuring the welfare of job seekers, wage earners, and retirees. It oversees various labor laws, including those related to workplace safety, minimum wage, and unemployment benefits. The DOL also collects and analyzes data on employment and labor trends. The department is divided into several agencies, such as the Occupational Safety and Health Administration (OSHA) and the Bureau of Labor Statistics (BLS). These agencies work together to enforce regulations and provide resources that help protect workers' rights and improve working conditions across the country.
