Ongaro's only ally among the 62 unions was initially the sanitary workers' Amado Olmos, and the duo were no match for Alonso's conciliatory strategy with the repressive new regime of General Juan Carlos Onganía.

Where Ongaro had Perón's own support, Vandor could only boast the endorsement of Onganía's new Labor Minister, Rubens San Sebastián, the architect of the President's "divide and conquer" strategy towards the CGT.

Tosco's support of a local autoworkers' strike at the important Córdoba FIAT plant in May 1969 was decisive in the demonstrations' brutal May 29 repression, whose subsequent riots became known as the Cordobazo.

Reunited with other former CGTA allies including Agustín Tosco and steelworkers Francisco "Barba" Gutiérrez and Alberto Piccinini, Ongaro organized a conflict resolution committee geared for the defense of targeted unions.

The overthrow of Peru's populist dictator, Juan Velasco Alvarado, the following day led to an increasingly hostile climate for left-wing Argentine exiles in general, and Ongaro departed for Spain in June 1976.

[2] Ongaro was reelected Secretary General of the FGB, which, despite its recent ordeal, still counted with around 25,000 members and remained Argentina's largest print workers' union.

Adverse to conflict, Ongaro refused to condemn Menem's October 1989 pardon of those who led Argentina's last dictatorship during its infamous 1976-79 campaign of human rights abuses.

[7] The FGB's relatively conciliatory stance in collective bargaining negotiations fostered the emergence in 2011 of a rival faction, the Eduardo Ayala Classist Graphics Group.
