In the article, we will explore the impact of platform labour on urban spaces and the new frontiers of unionism by leveraging a ground analysis and theoretical elaborations from the PLUS project. PLUS was designed to analyse the impact of four platforms (Uber, Airbnb, Helpling, and Deliveroo) in seven European cities (Barcelona, Berlin, Bologna, Lisbon, Paris, London, and Tallinn). In doing so, PLUS supported its sociological investigations with theoretical and historical elaborations concerning the operation of contemporary platforms and the characteristics of the new form of unionism. We will present some results from PLUS, with a focus on the Bologna case, where platform workers express their dissatisfaction with their organizations, attempting to relate their strategies to certain structural aspects of business territorialization within urban spaces. We will draw upon the well-known distinction proposed by Albert Hirschman between exit, voice, and loyalty and adapt it to frame the various strategies that platform workers may adopt.
