This article develops a multi-level framework for the analysis of a bottom-up politics of technology at the workplace. It draws on a multi-case study on algorithmic management of manual labor in manufacturing and delivery platforms in Germany. In researching how workers influenced the use of algorithmic management systems, the concept of technopolitics is developed to refer to three different arenas of negotiation: (1) the arena of regulation, where institutional framings of technologies in production are negotiated, typically between state actors, employers’ (...) associations, and unions. (2) The arena of implementation, where strategies of technology deployment are negotiated—in the German production model typically between management and works council. (3) The arena of appropriation, in which different organizational technocultures offer contesting schemes for the actual use of technology at work. Whereas most recent research on digitalization of work conceptualizes workers as mere objects of digitalization processes, this paper focuses on worker agency as a “technopolitics from below.” It thus demonstrates how workers influence the concrete outcome of digitalization projects.
