for embodied energy. Accounting for such a system would be vastly more complex than current or other theoretical currency systems because all energy output of workers and energy expenditure on goods/services must be tracked (something that is thought impossible and useless by many anarchists). One group that has advocated a system using energy is the technocracy movement with a system based on energy accounting where energy is used to "buy" a product or service without being exchanged, so the effect is that products or services are distributed to the user without gain by the provider (who has the same amount of energy in his or her account regardless) so allegedly making profit impossible. Workers issues and anarcho-syndicalism Anarcho-syndicalism is a branch of anarchism which focuses on the labour movement. Syndicalisme is a French word, ultimately derived from the Greek, meaning "trade unionism"—hence, the "syndicalism" qualification. Syndicalism is an alternative co-operative economic system. Adherents view it as a potential force for revolutionary social change, replacing capitalism and the state with a new society democratically self-managed by workers. The basic principles of anarcho-syndicalism are workers' solidarity, direct action and workers' self-management. 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' organizations (the organizations 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 labor in his 1938 pamphlet Anarcho-Syndicalism. The International Workers' Association is an international anarcho-syndicalist federation of various labor unions from different countries. The Spanish Confederación Nacional del Trabajo (CNT) played and still plays a major role in the Spanish labor movement. It was also an important force in the Spanish Civil War. Anarcho-syndicalists seek to abolish the wage system, regarding it as "wage slavery" and state or private ownership of the means of production, which they believe lead to class divisions. Not all seek to abolish money per se. Ralph
