Taft-Hartley Act Definition
The Taft-Hartley Act severely restricts the activities and power of labor unions in the United States. The Act, officially known as the Labor-Management Relations Act, was sponsored by Senator Robert Taft and Representative Fred Hartley. U.S. President Harry S. Truman described the act as a "slave-labor bill" and vetoed it. The United States Senate followed the United States House of Representatives in overriding Truman's veto on June 23, 1947, establishing the act as law.
