The Laborers' International Union of North America (LIUNA) is a diverse labor union representing workers primarily in the construction industry, but also in various other sectors. Founded in 1903, LIUNA members perform a wide range of tasks essential to building and maintaining infrastructure. Laborers often handle the foundational work on construction sites, including site preparation, excavation, and concrete pouring. They build scaffolding, operate small machinery, and assist with demolition. LIUNA members also work in areas such as hazardous waste removal, asbestos abatement, and tunnel construction. Beyond construction, the union represents workers in fields like healthcare, municipal services, and food service. LIUNA is known for its emphasis on training programs that help members acquire new skills and adapt to changing technologies in their industries. The union advocates for fair wages, workplace safety, and comprehensive benefits for its members across the United States and Canada.
