In Our Union, Jason Russell argues that the union local, as an institution of working-class organization, was a key agent for the Canadian working class as it sought to create a new place for itself in the decades following World War II. Using UAW/CAW Local 27, a composite union in London, Ontario, as a case study, he offers a ground-level look at union membership, including some of the social and political agendas that informed union activities. Drawing on interviews with former members of UAW/CAW Local 27 as well as on archival sources, Russell offers a narrative intended to speak not only to labour historians but to union members themselves.
