In this contribution, we argue that critical theories of the public sphere (in Habermas, but also in Negt and Kluge as well as Fraser) leave out the socially central field of labour and labour-political disputes, and that a reactualization and refocusing becomes necessary: We define the dynamics of globalization, commodification and digitalization as sequences of a renewed structural transformation of both social self-understanding and gainful employment. With the help of a multi-level model of labour-political publics and counter-publics, class mobilizations can be examined with a public-theoretical lens and important moments of labour-political disputes can also be reflected on their communicative conditions. This is exemplified by two vignettes.
