The growth of digital platforms is spawning new, if often precarious, forms of work. One such type of work that has particularly grown in recent years, especially during the COVID-19 pandemic, is that of digital platform-facilitated on-demand food delivery services. Such deliveries are often undertaken by younger workers. Given this, here we explore the following research questions: (i) what forms of labour precarity are found and reproduced in the physical and digital spaces that young food delivery platform (FDP) workers create and inhabit?; and (ii) what types of agency do FDP workers develop within these spaces in order to navigate – and sometimes resist – precarity? Drawing upon concepts from critical Youth Studies, Geographical Political Economy and Labour Geography, the article develops the concept of precarious youthspaces of work to investigate the connections between youths’ everyday lives and the production of space. To do so we present a qualitative study conducted in Athens, Greece, that sought to capture the multifaceted working arrangements of FDP workers, both offline and online. Our analysis reveals that FDP workers suffer various forms of labour precarity which they must navigate. But such workers are not just accommodating to precarity. They have also generated forms of collective oppositional agency that are reshaping local labour markets. However, whilst their agency has sometimes generated solidarity and robust collective movements it has also led to divisions that have limited cooperation amongst FDP workers.
