“…The book that we present here continues and advances on the investigations carried out in the last period, providing a set of original works that examine little-reported aspects of the Creole revolutionary syndicalist current during the period prior to the first government of Hipólito Yrigoyen (1916-1922), the mandate itself and the subsequent moment, already under the presidency of Marcelo T. de Alvear (1922-1928). Starting from a careful study of primary sources, the chapters investigate aspects such as: the syndicalist political formation prior to 1916; militancy and organization in the wood industry; the activation of revolutionary unionism among rural workers; the link between trade unionism and the world of women's work; the positions and struggles within the current around the state project of legal status for unions…”
