Step-by-step explanation:
The second phase of personnel management in the 1930s was marked by significant regulatory changes that affected the rights and conditions of workers in the United States. One of the landmark pieces of legislation was the National Labor Relations Act of 1935, also known as the Wagner Act, which provided workers with the right to organize unions and set the stage for a significant increase in union membership.
