Taft-Hartley Act

The Taft-Hartley Act is a United States federal law that restricts the activities and power of labor unions, enacted by the 80th United States Congress over the veto of President Harry S. Truman on June 23, 1947. The law was introduced in response to a major strike wave in 1945 and 1946, and it amended the 1935 National Labor Relations Act, adding new restrictions on union actions and designating new union-specific unfair labor practices. The act prohibited practices such as jurisdictional strikes, wildcat strikes, and monetary donations by unions to federal political campaigns, and allowed states to enact right-to-work laws banning union shops.learn more on wikipedia
