Confédération Générale du Travail-Syndicaliste Révolutionnaire
The Revolutionary Syndicalist General Confederation of Labour (French: Confédération Générale du Travail – Syndicaliste Révolutionnaire; CGT-SR) was a French national trade union centre. It emerged out of the libertarian faction of the Unitary General Confederation of Labour (CGTU) and split away after it came under the control of the French Communist Party (PCF).
