The National Labor Relations Act of 1935 — universally called the Wagner Act after its Senate sponsor, Robert F. Wagner Sr. of New York — was the most ambitious legislative intervention in the history of American labor relations. It guaranteed private-sector workers the right to organize, established collective bargaining as the legally mandated framework for resolving labor-management disputes, and created the National Labor Relations Board as the enforcement agency of those rights. In doing so, it did not merely regulate labor markets; it constituted a new architecture of collective power for the American working class. The Act's preamble was explicit about its purpose: to address the inequality of bargaining power between employers and employees, to sustain the purchasing power of workers, and to prevent the industrial strife that arose from employer refusals to bargain in good faith.
For roughly two decades, the Wagner Act's framework functioned as intended. Union membership tripled between 1935 and 1947. Industries that had successfully resisted organizing for generations — steel, automobiles, rubber, electrical manufacturing — were organized in rapid succession. Real wages for production workers rose substantially. Collective bargaining agreements began to include not merely wage provisions but pensions, health insurance, seniority protections, and grievance procedures — the architecture of what historians call the mid-century social contract.
The Act's erosion began almost immediately with its passage. Employers challenged it in the courts (it was upheld by the Supreme Court in NLRB v. Jones & Laughlin Steel in 1937), formed the National Association of Manufacturers' counter-campaign, and maintained private research into every legal avenue of circumvention. The Taft-Hartley Act of 1947 was the first major legislative assault: it prohibited closed shops, allowed states to enact right-to-work laws, banned secondary boycotts, created a framework for decertification elections, required union officers to sign anti-communist affidavits, and permitted employers to give speeches to workers during organizing campaigns. Taft-Hartley did not destroy the Wagner framework, but it fundamentally altered the power balance within it.
The erosion intensified in subsequent decades through a combination of administrative weakening, judicial reinterpretation, and structural economic change. The NLRB's enforcement mechanisms were undermined by slow case processing — the median time from unfair labor practice charge to remedy stretched from months to years. Penalties for employer violations remained so modest that legal violation became a rational business strategy: the expected cost of firing union organizers was far lower than the expected cost of unionization. The Board's composition fluctuated with presidential administrations, producing whipsaw shifts in interpretive doctrine. By the 1980s, what had been established as a worker's right was functioning more like a paper guarantee.
The most important structural change was the exclusion from NLRA coverage of categories of workers whose size and significance were not anticipated in 1935. Agricultural workers and domestic workers — excluded in the original Act, reflecting the political accommodation of Southern Democrats whose constituents depended on Black and immigrant labor in those sectors — were never brought within coverage. Supervisors were excluded by Taft-Hartley. Independent contractors, a category whose boundaries employers learned to expand aggressively through worker misclassification, were excluded from the start. By the twenty-first century, the categories of worker not covered by the Act had grown to encompass tens of millions of people in some of the most rapidly expanding sectors of the economy.
The erosion of the Wagner Act is not simply a legal history; it is a story about the relationship between law and power. Law does not enforce itself; it is enforced by agencies whose composition, resources, and political orientation are determined by broader political struggles. When the political coalition that built the NLRA framework lost power — gradually through the postwar decades, dramatically under Reagan — the institutions that had given the Act its force were staffed, funded, and directed by people skeptical of the Act's original purposes. The formal text remained; the functional enforcement apparatus hollowed out.
Law 3 — Connect — illuminates the Wagner Act as an instrument for institutionalizing connection at scale. Its central contribution was not simply to protect individual workers but to create the legal space and the procedural architecture through which workers could build durable collective relationships across a workplace, an industry, or a sector. The erosion of the Act is thus the erosion of a public infrastructure for connection — one that, unlike private social networks or informal community ties, was backed by the coercive authority of the state. Rebuilding adequate collective infrastructure for the twenty-first century requires understanding both what the Wagner Act achieved and precisely how and why its architecture failed to sustain itself against sustained and sophisticated opposition.
