The National Labor Relations Act of 1935, or Wagner Act, is a cornerstone of U.S. labor law, guaranteeing private-sector workers the right to form unions, negotiate collectively, and participate in strikes, while preventing employer interference. Central to its design was the creation of the National Labor Relations Board (NLRB) to enforce these rights and mediate disputes.
The Act aimed to correct power imbalances between employers and employees, though it excluded groups such as agricultural workers and government employees. Legal interpretations by justices like Hugo Black and Harlan F. Stone emphasized its support for collective action, while court decisions defined its boundaries in relation to state regulations. The Wagner Act continues to be essential in shaping labor relations, maintaining a balance between union rights and employer responsibilities through judicial review.
