This article is an analysis of minority political invention in the Industrial Workers of the World (IWW). Against the tendency in recent social and cultural theory to dichotomize class and difference, it argues that it was in and through the IWW's formulation of class that minority political and cultural invention occurred. Using the framework of Deleuze and Guattari's minor politics, the article shows how the IWW's composition in the simultaneously diffuse and cramped plane of work operated against the major political identities and subjects of worker, immigrant, American, citizen and 'people', and towards the creation of minority political knowledges, tactics and cultural styles premised on the condition that 'the people are missing'. Seeking to understand the IWW's modes and techniques of invention, the article explores the general plane of IWW composition, its particular political and cultural expressions (in songs, manifestos, cartoons and tactics), and its minor mode of authorship. The article focuses in particular on two aspects of IWW minority composition, the itinerant worker, or hobo, and the politics of sabotage.
