The Labor Management Relations Act of 1947, better known as the “Taft-Hartley Act” after its sponsors, U.S. Rep. Fred Hartley (R-N.J.) and U.S. Sen. Robert Taft (R-Ohio), made a series of amendments to the National Labor Relations Act (Wagner Act). While its best-known provision is a state option to enact a “right-to-work law” which prohibits compulsory agency fee provisions in private-sector workplaces, Taft-Hartley made a number of other changes to labor law including prohibiting secondary pickets and jurisdictional strikes, allowing employers to advocate against unionization, and banning Communists from labor union leadership (a provision later invalidated by the Supreme Court).
