What Was The American Federation Of Labor

The Basics of What Was The American Federation Of Labor

The American Federation of Labor was a national federation of labor unions founded in 1886 by Samuel Gompers. It became the dominant labor organization in the United States for decades, eventually merging with the CIO to form the AFL-CIO in 1955. Unlike some of its more radical competitors, it focused on concrete gains—wages, hours, benefits—rather than sweeping political revolution. The AFL operated on a craft union model. That means it organized workers by their specific trade—carpenters, machinists, railroad workers—rather than all workers in an industry together. This wasn't an accident. Gompers and the leadership believed skilled workers had more leverage because they were harder to replace. It was a deliberate strategy that shaped the entire structure of American unionism for most of the twentieth century. Here's what most people miss about the AFL: it wasn't just a big union. It was an umbrella organization. Each affiliated union kept its own independence, ran its own contracts, and made its own decisions. The AFL's role was largely coordination—setting priorities, providing legal support, backing strikes across affiliates when solidarity made sense. If you were a local carpenter in 1920, your real boss wasn't the AFL president. It was your own union's business agent and your collective bargaining agreement.

I spent years researching labor history and reading through primary sources, including union meeting minutes and correspondence between locals and the AFL headquarters. One thing that stood out was how much internal friction existed. The AFL constantly battled with the Knights of Labor before its formation, then with the Industrial Workers of the World after 1905, and later with the Congress of Industrial Organizations over the jurisdictional line between craft and industrial unionism. Those fights weren't theoretical. They involved actual strikes, rival picket lines, and members switching allegiances. The AFL's approach to politics was calculating. Gompers was no socialist. He pushed for what he called "pure and simple unionism"—bargaining at the bargaining table rather than trying to capture government. That didn't mean the AFL stayed out of politics entirely. It lobbied heavily for protective legislation like the eight-hour day for federal workers, safety regulations, and restrictions on child labor. The strategy worked reasonably well until the New Deal changed the landscape entirely. The Norris-La Guardia Act of 1932 and the Wagner Act of 1935 shifted the terrain. Government started backing the right to organize, and the AFL found itself in a surge of membership it hadn't predicted. But the same act also empowered the CIO, which organized along industrial lines and took members from AFL affiliates. The rivalry between the two federalions was brutal. It wasn't resolved until pressure from the Department of Justice and the Kennedy administration forced a merger in 1955.

If you're trying to understand how the AFL compares to modern labor organizations, the key difference is scope. The AFL focused on skilled trades and workplace-level bargaining. Modern unions like Service Employees International or the Alliance of State and Municipal Employees represent service and public-sector workers with a very different set of challenges. The craft model doesn't translate cleanly to gig economy work or decentralized workplaces. One practical detail that comes up often: the AFL's constitution required affiliated unions to have a minimum number of members and a demonstrated track record of collective bargaining. This was meant to keep out radicals and ensure stability, but it also meant that growing industries with unorganized workforces—like meatpacking or auto—often fell through the cracks. That gap is exactly what the CIO exploited in the late 1930s. The legacy is complicated. The AFL-CIO still exists and remains the largest labor federation in the United States, but union density has declined steadily since the 1950s. The strategies that made the AFL successful in its era—craft jurisdiction, negotiated agreements, political lobbying—face serious headwinds today. Declassification of employer anti-union tactics in the 1990s and early 2000s revealed the extent of union-busting infrastructure that built up during the postwar period. That history matters for understanding why organizing campaigns still face such steep odds.
