 Anarcho-syndicalists believe that only direct action – that is, action concentrated on directly attaining a goal, as opposed to indirect action, such as electing a representative to a government position – will allow workers to liberate themselves. Moreover, anarcho-syndicalists believe that workers' organisations (the organisations that struggle against the wage system, which, in anarcho-syndicalist theory, will eventually form the basis of a new society) should be self-managing. They should not have bosses or "business agents"; rather, the workers should be able to make all the decisions that affect them themselves. Rudolf Rocker was one of the most popular voices in the anarcho-syndicalist movement. He outlined a view of the origins of the movement, what it sought, and why it was important to the future of labour in his 1938 pamphlet Anarcho-Syndicalism. The International Workers Association is an international anarcho-syndicalist federation of various labour unions from different countries. The Spanish Confederación Nacional del Trabajo played and still plays a major role in the Spanish labour movement. It was also an important force in the Spanish Civil War.
