The Wagner Act (1935) strengthened labor unions by establishing the federal government as the ultimate arbiter of labor relations, providing a legal framework that protected workers' rights to organize and engage in collective bargaining.12
Key ways the act empowered unions included:
- Legal Protections: It prohibited employers from interfering with the right to organize, dominating company-established unions, or discriminating against workers for joining a union.12
- Enforcement Mechanisms: It created the National Labor Relations Board (NLRB) to conduct secret-ballot elections to determine union representation and to investigate and correct unfair labor practices by employers.31
- Mandatory Bargaining: Employers were legally required to bargain in good faith with unions certified by the NLRB as the choice of a majority of employees.12
By formalizing these rights, the act removed significant power advantages previously held by employers, helping union membership in the United States more than double between 1930 and 1940.24
