In the 1960s, when André Bergeron became leader of the Confederation, the links between FO and the French Section of the Workers' International (SFIO) became distended. Indeed, if Bergeron was an SFIO member, he was also the "main partner" of the employers and the right-wing governments. In this, FO presided the social security offices. Besides, it welcomed Conservatives and Far-Left, notably members of the Trotskyist Internationalist Communist Organization. The hostility to the CGT and to the French Communist Party is the cement of the confederation.
