Answer:
The answer is National Labor Relations Act (Wagner Act)
Explanation:
The national labor Act of 1935 provides workers with the right to organize and join labor union. The Act also provides workers with a framework for collective bargaining. The Wagner Act prohibits the interference or coercion of workers to exercise their rights of organizing or joining labor unions alongside bargaining collectively for their working conditions or wages.
Moreover, the Act prohibits the employer from the refusal to bargain with employees' representatives.
