Despite the large number of working-class students having to work while attending schools, their work experience and the potential of class solidarity have been largely unaddressed. By bringing in a social psychological perspective, this year’s ODS Lecture revives the sociological debates on working-class solidarity and challenges the defeatist view of solidarity since the neoliberal turn of the global economy. Professor Pun discusses how working-class solidarity can be built and consolidated, through layers of prosocial behaviours, by students with work experience.
