 Rucci strongly opposed the unionist Agustín Tosco, the leader of the Córdoba trade union "Luz y Fuerza", who held a more leftist position than Rucci, and opposed the syndical bureaucracy's "participationist" (pragmatic) stance towards the military government of General Juan Carlos Onganía, installed in 1966.The CGT split into the conservative "Azopardo" branch (named after the headquarters' address in Buenos Aires), and the CGT de los Argentinos (CGTA) following the annulment of left-wing graphist workers' leader Raimundo Ongaro as secretary general.The eventual "Cordobazo" of May 1969 led to the CGT-Azopardo's placement in receivership (the CGTA had been banned from the start), though in December, the order was lifted.
