The General Confederation of Labor (Spanish: Confederación General del Trabajo, CGT) is a Spanish trade union federation.
The CGT was a result of a split in the anarchist National Confederation of Labor (CNT). In 1979, at the first CNT congress after Spain's transition to democracy, there was a fundamental disagreement concerning union elections. Such elections allow Spanish workers to elect union delegates to factory committees every four years. Some deemed this a renewal of anarcho-syndicalism, but the more orthodox in the organization considered such elections a "government intervention in labor–capital relations". Moreover, this would involve receiving state funding. The two factions split and there were two CNTs. They fought over ownership of the name CNT. In 1989, the orthodox CNT prevailed in court and the renovators took the name CGT.
