General Confederation of the Surtaline Workers

1925-1947
Following its annexation by Nacarv Hisqaida in 1940, the organization was illegalized, only being legalized again following its liberation by the Allied forces near the end of World War II.

1947-1990
Following the 1967 coup d'état that led to the establishment of a military regime, the CGTS was illegalized by the Government for its ties with the Surtaline Communist Party, leading it to operate clandestinely until it was legalized once more in 1981.
