In this paper we will analyze the call that the CGT de los Argentinos made to incorporate into their media of graphic circulation, the Semanario CGT, the direct testimony of workers who adhered to the causes that this workers' central proposed. Addressing first what has been written about the subject in question, we will establish the context in which this experience is inscribed (from the historical as well as the organizational). Our goal is to inquire about the place that this working modality occupied in the Semanario in the construction of the political identity of the CGTA. We will identify it from the analysis of the notes written by workers' bases between 1968 and 1970, which responded to the call made by the editors of the weekly. We will also explain what other ways of encouraging worker participation were explained in the Semanario, as well as the setbacks and debates that generated this initiative.
