Staunchly anti-Communist, in 1975 the CGT affiliated itself with the International Confederation of Free Trade Unions (ICFTU). Following the March 1976 coup, however, 10,000 factory delegates, on a total of 100,000, were arrested. During the Dirty War of the second half of the 1970s at least 2,700, or 30%, of the disappeared were blue-collar workers; this included numerous CGT leaders and activists, notably René Salamanca of the Córdoba Auto Workers' Union and Light and Power Union leader Oscar Smith. At first temporarily suspended, the CGT was then dissolved by the junta. Despite having been outlawed, by 1978 the CGT unions had reorganized themselves into two factions: one supporting frontal opposition to the dictatorship (known initially as the "Commission of 25"), and the other supporting negotiation with the military, named at first CNT and then CGT-Azopardo (led by Ramón Baldassini and Jorge Triaca); both the CGT-Brasil and the CGT-Azopardo were named after the streets on which the headquarters were located. CGT-Azopardo was thus able to negotiate with the military dictatorship the control of employee health insurance organizations.
