The National Labor Relations Act 1935
President Franklin D. Roosevelt signed this bill, sometimes known as the Wagner Act, into law on July 5, 1935. It established the National Labor Interactions Board and addressed the issue of private-sector union-employer relations.
After the Supreme Court deemed the National Industrial Recovery Act unconstitutional, organized labor sought redress against companies who had been permitted to spy on, question, discipline, dismiss, and blacklist union members. Workers began to organize militantly in the 1930s, and a wave of strikes erupted across the country in the form of citywide general strikes and plant takeovers in 1933 and 1934. Workers attempting to organize unions clashed violently with police and private security forces supporting the interests of anti-union companies.
