One Big Union (concept)

The One Big Union is an idea originating in the late 19th and early 20th centuries amongst trade unionists to unite the interests of workers and offer solutions to all labour problems.

Unions initially organized as craft unions. Workers were organized by their skill: carpenters, plumbers, bricklayers, each into their respective unions. Capitalists could often divide craft unionists along these lines in demarcation disputes. As capitalist enterprises and state bureaucracies became more centralized and larger, some workers felt that their institutions needed to become similarly large. A simultaneous disenchantment with the perceived weakness of craft unions caused many unions to organize along industrial lines. The idea of the "one big union" is championed by anarchist syndicalists to organize effectively.

As envisioned by the Industrial Workers of the World (IWW), which for many years prior to 1919 had been associated with the concept,^[1] One Big Union was not just the idea that all workers should be organized into one big union. In the 1911 pamphlet One Big Union, IWW supporters Thomas J. Hagerty and William Trautmann enumerated two goals: One Big Union needed to "combine the wage-workers in such a way that it can most successfully fight the battles and protect the interests of the workers of today in their struggles for fewer hours of toil, more wages and better conditions," and it also "must offer a final solution of the labor problem – an emancipation from strikes, injunctions, bull-pens, and scabbing of one against the other."^[2]

One Big Union was the notional organizational concept, while the IWW's revolutionary industrial unionism was the organizing method by which that concept could be realized. "Organizing the One Big Union of all workers the world over" was meant to achieve "working class control".^[3] But the One Big Union organizations were resisted by government and industry, and subverted by existing trade unions. By 1925, only the slogan of One Big Union remained.^{[citation needed]}
