Century Of Service Honor Roll Of American Labor Organizations

The Century of Service Honor Roll of American Labor Organizations honors labor unions that have reached their 100th anniversary. This Honor Roll originated in 1992 under Secretary of Labor Lynn Martin.

With Secretary Elaine L. Chao's induction in 2003 of the International Brotherhood of Teamsters, the Laborers' International Union of North America, the International Association of Heat and Frost Insulators and Asbestos Workers, and the National Rural Letter Carriers' Association, forty-five unions are now included in the Century of Service Honor Roll.

The Century of Service exhibit is located in the North Plaza of the U.S. Department of Labor's Frances Perkins Building, 200 Constitution Ave NW, Washington, D.C.

The exhibit is maintained by the Office of the Assistant Secretary for Administration and Management and is open to the public during government working hours.
