Final answer:
The Wagner Act revived labor by protecting workers' rights to form unions and bargain collectively, established the NLRB to enforce these rights, and prohibited unfair labor practices by employers, leading to an increase in union membership and labor activism.
Step-by-step explanation:
The Wagner Act, officially known as the National Labor Relations Act, was enacted in 1935 to empower American workers. It protected their rights to create unions and bargain collectively with employers. A pivotal element of the Wagner Act was the establishment of the National Labor Relations Board (NLRB), a body designated to enforce the act's provisions and arbitrate labor disputes. Furthermore, this act responded to the Supreme Court's nullification of the National Industrial Recovery Act, which had previously granted these worker rights.
The Wagner Act's provision that prohibited employers from engaging in unfair labor practices, such as discrimination against union members or firing workers for striking, was crucial in protecting labor rights. It significantly increased union membership, aided in industrial workers' ability to negotiate for better wages and working conditions, and fostered the rise in labor activism and strikes, exemplified by events such as the sit-down strike in Flint, Michigan.
