noun
- an act of the U.S. Congress (1947) that supersedes but continues most of the provisions of the National Labor Relations Act and that, in addition, provides for an eighty-day injunction against strikes that endanger public health and safety and bans closed shops, featherbedding, secondary boycotts, jurisdictional strikes, and certain other union practices.
A major law concerning labor, passed by Congress in 1947. President Harry S. Truman vetoed Taft-Hartley (see veto), but it became law by a two-thirds vote of Congress. It marked a reversal of the pro-labor policies pursued under the presidency of Franklin D. Roosevelt. For example, the law prohibited a list of “unfair” labor practices and restricted the political activities of labor unions.
