Industrial unionism
Industrial unionism is a way of organizing workers where everyone in the same industry (regardless of job or skill) joins the same union. The idea is to pool the bargaining power of all workers in that industry, which can give them more leverage in negotiations and during strikes. This is different from craft unions, which organize workers by specific trades (like carpenters or electricians) rather than by industry as a whole.
The movement began in the United States in the late 19th century. In 1893, Eugene Debs and other railway workers formed the American Railway Union (ARU) as an industrial union to challenge the limits of craft unions. Debs argued that organizing by craft left some workers out in key fights. A telling example came in 1888 when a strike by train drivers and firemen didn’t bring along conductors, who belonged to different unions, allowing employers to hire strikebreakers.
The ARU’s most famous moment came in 1894 with the Pullman Strike. The ARU’s boycott quickly shut down traffic from Chicago to the West, and the sympathy strike spread to other regions. Company leaders and the General Managers Association warned that they could “handle” the railway brotherhoods but could not handle Debs and the ARU. The federal government responded decisively, sending troops to end the strike.
In 1905, the Industrial Workers of the World (IWW) was formed in Chicago. It rejected the AFL’s craft unionism and aimed to organize workers by industry regardless of sex, race, or nationality. The IWW promoted a One Big Union of all wage workers and argued that workers and employers had nothing in common. From its start, the IWW faced fierce opposition, including violence, raids, and harsh press scrutiny. Its members and leaders were attacked, jailed, or killed, and governments in the US and other countries passed laws to curb its activities. Despite this, the IWW helped popularize the idea that industrial unionism should unite workers across industries and professions.
A key concept tied to industrial unionism is the One Big Union (OBU), the idea of forming a single, united labor movement that would outgrow the old divisions between trades. Supporters like Verity Burgmann have noted that in places like Australia the IWW offered an alternative to traditional political labor parties and to Bolshevik-style unions, envisioning a broad, mass-based movement focused on the industrial economy.
Today, industrial union ideas have influenced unions around the world. For example, the Korean Confederation of Trade Unions (KCTU) and South Africa’s Congress of South African Trade Unions (COSATU) organize along industrial lines. Historical figures and movements in Britain also debated industrial unionism, with early experiments like the Grand National Consolidated Trades Union and later shifts toward combining craft and industrial organizing.
In the United States, the tension between craft and industrial organizing shaped the early 20th century. The AFL favored craft unions, and when the United Mine Workers formed as an industrial union, others resisted encroachment on their “turf.” This push-and-pull helped set the stage for the creation of the Congress of Industrial Organizations (CIO) in the 1930s, which practiced industrial unionism more fully. After World War II, the CIO merged with the AFL in 1955 to form the AFL–CIO, which kept a mix of craft and industrial union approaches.
Industrial unionism remains a powerful idea: the notion that when workers unite across an entire industry, they gain greater power to win shorter hours, higher pay, and better working conditions, both in and out of the workplace.
