Labor Management Relations Act
- A 1947 law that modified the earlier National Labor Relations Act of 1935, which strongly favored unions. The Labor Management Relations Act preserved the rights of workers to join unions and engage in collective bargaining, but also made it equally legal not to join a union. It allowed union-only rules if the state law permitted them and a majority of workers voted in favor. The law mandated unions to give a two-month notice prior to a strike and allowed the government to intervene and halt a strike for up to 80 days if it posed a threat to national health or safety. It also clarified what actions would be considered unfair from both labor and management. This law further put a limit on union political contributions and prohibited union officers from having any affiliations with the Communist Party
- Under the Labor Management Relations Act, the workers were allowed to vote for or against forming a union shop.
- The union provided a 60 days' strike notice as per the requirement of the Labor Management Relations Act.
- The prohibition on secondary boycotts, as delineated in the Labor Management Relations Act, bars unions from extra pressure tactics.
