The Railroad Labor Board (RLB) was an institution established in the United States of America by the Transportation Act of 1920. This nine-member panel was designed as means of settling wage disputes between railway companies and their employees. The Board's approval of wage reductions for railroad shopmen was instrumental in triggering the Great Railroad Strike of 1922. The Board was terminated on May 20, 1926 when President Calvin Coolidge signed a new Railway Labor Act into law.
