A political movement that urges the abolition of government and the collectivization of industry. Anarcho-syndicalists believe that such a change can come about only with "One Big Union" of all workers (syndicalism is from the French word for union). Anarcho-syndicalists tend to draw a distinction between trade unions and industrial unions.

The IWW provides an example of anarcho-syndicalism. Also, the CNT of Spain--one of the factions that fought in the Spanish Civil War.
