Established in 1992 by Secretary of Labor Lynn Martin, the Century of Service Honor Roll of American Labor Organizations honors labor unions that have reached their 100th anniversary and their contributions in American history.
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. It features a series of panels with each union's seal or logo.
The exhibit currently commemorates the centennials of more than 50+ labor unions across North America. Additional labor organizations will be added to the Honor Roll as they reach their one-hundredth anniversary.
The Department of Labor acknowledges the unparalleled contributions made by the labor movement and recognizes the legacy unions have had in building the U.S. economy and middle class.
The Department acknowledges the cooperation and assistance of the participating labor organizations in providing their seals or logos and historical information. The seals and logos are the property of the labor organizations and may not be duplicated without permission.
The exhibit is maintained by the Office of the Assistant Secretary for Policy and is open to the public during government working hours.
