How did the Wagner Act affect labor unions?

answer:

It gave employees the right, under Section 7, to form and join unions, and it obligated employers to bargain collectively with unions selected by a majority of the employees in an appropriate bargaining unit.

Answer:Its principal goal was to make it lawful for the majority of workers—with the notable exception of domestic and agricultural workers—to form or join labour unions and engage in collective bargaining with their employers.

Explanation:  

The Wagner Act, sponsored by Democratic Sen. Robert F. Wagner of New York, made the federal government the only arbiter and regulator of labour relations. It established the National Labour Relations Board (NLRB), a permanent body of three members (later increased to five), with the authority to hear and decide labour disputes through quasi-judicial processes. In particular, the NLRB had the authority to conduct secret ballot elections in which workers in a company or industry could choose whether to be represented by labour unions, determine whether an appropriate bargaining unit of employees existed for collective bargaining, and prevent or address unfair labour practises by employers (later also by unions). The law forbade employers from using unfair labour practises like forming a business.
