In the 1920s, Barc Corporation, a coal manufacturing company, refused to negotiate its wage policy with its employees. It also refused to bargain with the elected union members. In the given scenario, Barc Corporation violated the:

A) Wagner Act.
B) Sherman Antitrust Act.
C) Rowlatt Act.
D) Publicity Act.

The Wagner Act, also known as the National Labor Relations Act of 1935, was designed to protect the rights of employees and employers, to encourage collective bargaining, and to curtail certain private sector labor and management practices, which can harm the general welfare of workers, businesses, and the U.S. economy. Although the Wagner Act was not in effect during the 1920s (it was enacted in 1935), Barc Corporation's refusal to negotiate wage policy with its employees or to bargain with elected union members would have been a violation of this act, as it protects the right of workers to organize and to bargain collectively through representatives of their own choosing.
