The Taft-Hartley Act (known formally as the Labor Management Relations Act of 1947) is a set of amendments to the federal National Labor Relations Act (NLRA) passed after the Second World War to promote industrial peace and correct the pro-organized-labor bias of the New Deal-era Wagner Act (the un-amended NLRA).
The Labor Management Relations Act of 1947, better known as the Taft–Hartley Act, is a United States federal law that restricts the activities and power of labor unions. It was enacted by the 80th United States Congress over the veto of President Harry S. Truman, becoming law on June 23, 1947.
