 In early June 1970, Osvaldo de Melo and Sara del Carmen Zaldivar had a modest tabloid project, conceived by the second, to the then general secretary of CTC, Hector Ramos Latour.Since then, Los Trabajadores –its initially name- would supply the void caused by the disappearance of Vanguardia Obrera and the Revista CTC, CTC and trade unions publications that for many years reported and guided to on key issues of union events.The first number, printed on the first half of June, was followed by another in the second half of July and one in November, also in the second half.
