An Analysis of Trade Union Restrictions in the Wisconsin Employment Peace Act

Trade union membership rose from less than three million in 1932 to more than 15 million in 1949. In 1946 (the latest year for which information is available) nearly 70 percent of all non-agricultural wage and salaried workers were covered by collective bargaining agreements. This growth has been attributed primarily to the attitude of government in encouraging labor unions with the enactment of the Norris-LaGuardia Anti-Injunction Act in 1932 and the National Labor Relations (Wagner) Act of 1935.
