Congress enacted the National Industrial Recovery Act (NIRA) as an early New Deal response to the Great Depression. Section 7(a) promised that employees could organize and bargain collectively without employer interference, but enforcement was weak and contested. The gap between the promise and the reality helped drive demands for a stronger, clearer labor law.
To handle disputes arising under NIRA Section 7(a), the Roosevelt administration created the National Labor Board (NLB). The NLB tried to mediate conflicts and encourage representation elections, but it lacked strong legal tools to force employer compliance. Its limited power became a central problem that later legislation aimed to fix.
In 1934, large and often violent labor conflicts spread across key industries and cities, including Toledo’s Auto-Lite strike and the West Coast waterfront strike. These confrontations drew national attention to employer resistance, uneven government response, and the limits of NIRA-era labor policy. The unrest strengthened arguments for a permanent federal system to protect organizing and bargaining.
Congress passed Public Resolution No. 44 to improve federal handling of labor disputes after the NLB struggled to enforce Section 7(a). The resolution empowered the president to create a stronger board with powers such as subpoenas and elections. It marked a shift from voluntary mediation toward more formal federal oversight.
President Franklin D. Roosevelt issued Executive Order 6763, replacing the National Labor Board with a new National Labor Relations Board. The statement accompanying the order emphasized investigations, labor elections, and hearing discharge cases, aiming to bring more order to labor relations. Even so, the board’s authority remained uncertain without a comprehensive statute.
In late 1934, Senator Robert F. Wagner reworked earlier labor proposals to solve the main problem of the NIRA era: rights without reliable enforcement. His approach centered on protecting employees’ organizing choices and requiring employers to bargain with majority-selected representatives. This drafting period set the basic design of what became the Wagner Act.
In February 1935, Wagner introduced the National Labor Relations Act in the U.S. Senate. The proposal aimed to move beyond mediation by creating an independent agency to enforce employee rights and oversee representation elections. Introducing the bill turned a general labor-policy debate into a specific legislative campaign.
In May 1935, the Senate approved Wagner’s bill, signaling strong support for a federal policy favoring collective bargaining. Passage reflected the belief that labor conflict could disrupt interstate commerce and recovery from the Depression. It also advanced the idea that an independent board should enforce rights, not just mediate disputes.
In A.L.A. Schechter Poultry Corp. v. United States, the Supreme Court ruled that major parts of NIRA’s industrial code system were unconstitutional. The decision ended the main legal framework that had carried Section 7(a), increasing pressure on Congress to enact a new, stand-alone labor law. The ruling helped make a replacement bill politically urgent.
In June 1935, the House of Representatives passed the Wagner Bill, sending it to President Roosevelt. The bill’s progress through both chambers showed that Congress was ready to replace the unstable NIRA approach with a dedicated labor-relations statute. This step completed the core legislative campaign before final enactment.
On July 5, 1935, President Franklin D. Roosevelt signed the National Labor Relations Act (the Wagner Act) into law. The act created a new National Labor Relations Board with stronger enforcement powers and set rules for union elections and collective bargaining in much of the private sector. It also defined and prohibited key employer “unfair labor practices,” including domination of “company unions.”
The NLRA’s effective date marked the transition from the NIRA’s temporary experiment to a lasting federal system for labor relations. With the law in force, the NLRB could run representation elections and issue orders aimed at protecting organizing and bargaining. This “end state” of the 1933–1935 campaign was a permanent national framework that shaped U.S. private-sector labor relations for decades.
