What does the Wagner Act primarily address?

The Wagner Act, officially known as the National Labor Relations Act of 1935, primarily addresses the rights of workers to organize and join labor unions. This landmark legislation aimed to protect the rights of employees to engage in collective bargaining and to take part in union activities without facing discrimination or retaliation from employers.

By establishing the National Labor Relations Board (NLRB), the act provided a framework for resolving disputes between trade unions and employers. It marked a significant shift towards recognizing the importance of organized labor in advocating for workers’ rights and improving working conditions, which ultimately contributed to the growth of unions and collective bargaining power throughout the United States.

The other options, while related to various aspects of workers' rights and economic policy, do not specifically encapsulate the core purpose of the Wagner Act as it centers chiefly on unionization and the rights of workers to collectively negotiate with their employers.
