Final answer:
The Wagner Act greatly influenced the labor movement by establishing federal support for collective bargaining, prohibiting discrimination against union members, and creating the National Labor Relations Board to enforce labor rights.
Step-by-step explanation:
The National Labor Relations Act (NLRA), also known as the Wagner Act, had a significant influence on the labor movement in the United States. Notably, the Wagner Act guaranteed the right to collective bargaining, a process through which workers, through their unions, negotiate contracts with their employers to determine their terms of employment, including pay, benefits, hours, leave, job health and safety policies, and more. The Act also prohibited certain unfair labor practices such as discrimination against union members and created the National Labor Relations Board (NLRB) to enforce its provisions and to resolve disputes between unions and employers. As a result of the Wagner Act, union membership expanded rapidly, bolstered by federal support for collective bargaining rights and the establishment of a framework to address labor grievances.
