IN 1937, in the case of National Labor Relations Board v. Jones & Laughlin Steel Corporation, the U.S. Supreme Court upheld the constitutionality of the National Labor Relations Act of 1935, or Wagner Act.
J&L Steel, the nation’s third largest steel company with major facilities in Aliquippa and Pittsburgh, had fired hundreds of men for union activity.
An ethnically diverse group of 10 fired workers filed an unfair labor practice charge demanding reinstatement and a government supervised union election. J&L then challenged the constitutionality of the National Labor Relations Act before the U.S. Supreme Court.
And lost, thus ensuring the newly-won rights of union organizrs and workers.
