how did the wagner act affect labor unions
The law was amended by the Taft-Hartley Act of 1947, also known as the Labor Management Relations Act (29 U.S.C.A. Â§ 141 et seq.), which balanced some of the advantages given to unions under the Wagner Act by imposing corresponding duties upon unions to deal fairly with management.he Wagner Act was one of the most dramatic legislative measures of the New Deal. Not only did the legislation indicate that the federal government was prepared to move against employers to enforce the rights of labor to unionize and to bargain collectively, but it imposed no reciprocal obligations on unions.
