Industrial Workers of the World

The Industrial Workers of the World (IWW), members of which are commonly termed "Wobblies", is an international, radical labor union that was founded in 1905. The union combines general unionism with industrial unionism, being a general union itself whose members are further organized within the industry of their employment. The philosophy and tactics of the IWW are described as "revolutionary industrial unionism," with ties to both socialist and anarchist labor movements. The origin of the nickname "Wobblies" is uncertain.
