“…Studies of conflict, control and cooperation in the labour process inspired by Burawoy’s (1979, 1985) work; of trade unions’ sociology using Hyman’s (1975, 2001) framework together with Kelly’s (1998) mobilization theory; and Silver’s (2003) longue dur é e comparative analysis of working classes mobilization, have influenced some of the most relevant book monographs of recent years (Ghigliani, 2010; Marticorena, 2014; Santella, 2016; Soul, 2014; Varela, 2015). The debate on union revitalization or renewal has also been used as a general frame of reference in various studies and edited books looking into institutional aspects of industrial relations (Etchemendy and Collier, 2007; Montes Cató and Delfini, 2015; Palomino and Trajtemberg, 2006; Senen Gonzalez and Del Bono, 2013; among others), as well as for studies investigating grassroots processes of workers’ organization and action (Atzeni and Ghigliani, 2013; D’Urso and Longo, 2017; Lenguita, 2011; Varela, 2015; Ventrici and Montes Cató, 2011). The latter studies fit closely with what can be considered a left approach to the revitalization debate concerned with the dynamics and factors influencing the construction of workplace power and the role of politics in this (Cohen, 2006; Darlington, 2009; Gall, 2013; Ness, 2014) and with unions’ democracy and identity (see the Capital and Class special issue on Hyman’s work, Gall and Darlington, 2012).…”
