Derived from post-industrial society experiences, current social theorists often argue that the working class no longer plays an active role in transforming society, thereby making the issue of working-class solidarity obsolete. This paper critically revisits Marx’s theories on solidarity and re-engages the debates by intersecting macro structural analysis with micro-foundation of working-class solidarity. The article formulates the concept of working-class solidarity in two layers of analysis: the first is a macro structural approach driven by class conflict, social grievance, and economic crisis directly connected to the social transformation of the neoliberal market economy; and the second looks at micro process of cooperation and mutual support at the level of everyday practice, that is, a collective-emotional environment that creates agency and a soft solidarity base for building bonds among working-class youth. The logic of solidarity is rescued through a multiplicity of working-class youth’s behaviors discovered in school and the workplace.
