The Italian General Confederation of Labour (CGIL) is a national trade union centre in Italy. It was formed by agreement between socialists, communists, and Christian democrats in the "Pact of Rome" of June 1944. But in 1950, socialists and Christian democrats split forming UIL and CISL, and since then the CGIL has been influenced by the Communist Party (PCI).
It has been the most important Italian trade union since its creation. It has a membership of over 5.5 million. The CGIL is currently the biggest trade union in Europe.
