One of the great pieces of legislation in the Second New Deal was the National Labor Relations Act, which considerably extended unions' rights when they were dealing with employers. By what name was this measure also known?

Roosevelt believed that he would have to become more radical for the New Deal to work successfully. So both before and after the election victory of 1936 he introduced a series of more robust measures: the Second New Deal. This aroused much opposition - in the usual quarters, but also from the guardians of the Constitution.
