Who We Are

Local 100 was chartered in 1915. 

Local 100 represents members in a wide variety of fields including healthcare, public employees, utilities and workers in the construction industry in the greater East St. Louis, Illinois vicinity. Local 100 is an affiliate of LIUNA- the Laborers' International Union of North America- the most progressive, aggressive, and fastest-growing union of construction workers, and one of the most diverse and effective unions representing public service employees.

LIUNA members unite through collective bargaining agreements that help us earn family-supporting pay, good benefits, and the opportunity for career advancement and better quality of lives. Members enjoy benefits unheard of for non-union workers. Government statistics show that the average pay for union construction workers is more than 50% above that of non-union construction workers. Also, union members are more likely to have healthcare and a pension-- 82% of union construction workers have health insurance, compared to only 46% of non-union construction workers and 77% of union construction workers have a pension plan, compared to only 35% of non-union construction workers. Members often become Leaders of their Local Unions. Local Unions fall under District Councils that work with Regions to serve the Local, while other Local Unions work independently with the Regional Office.
