The Argentine Workers' Central Union (Spanish: Central de Trabajadores de la Argentina, (CTA) is a trade-union federation in Argentina. Its general secretary is Hugo Yasky. It was formed in 1991 when a number of trade unions disaffiliated from the General Confederation of Labour (CGT). Though the CTA is a multi-tendency organization, it is led by unionists with a Social Christian viewpoint. There are also Peronist, Communist and Trotskyist minorities in the CTA.
