The Taft-Hartley Act has many serious and far-reaching defects.
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.
