This article investigates how institutional, organisational and individual factors influence labour politics in the internet economy. The authors discuss several theoretical approaches towards labour politics and industrial relations. Using the example of the IT industry, they then illustrate how in the IT industry the organisation of work changes, what requirements result for employees, how regulation is structured, and what political challenges this brings for trade unions and employer’s associations. Considering current developments in the IT economy, the authors finally evaluate the theoretical approaches according to their explanatory strength.
