Gentrification and labour precarisation constitute prominent responses to urban capitalist crises. They have typically been addressed in the literature as distinct processes. Even though they can indeed occur independently of one another, here we argue that they are also often deeply interconnected. To do so, we utilise a mix of fieldwork and secondary data to investigate how gentrification has both fostered labour precarisation but also how it has been supported by it, within a context of economic recession yet growing tourist inflows into two neighbourhoods (Koukaki and Kerameikos) in central Athens, Greece. Our findings show that the growth of precarious labour in construction has facilitated the development of several gentrification loci whilst, in turn, gentrification’s consolidation has encouraged the growth of poor working conditions in local lodging, hospitality/catering, and creative activities. Ultimately, in highlighting the role of labour precarisation in gentrification, the paper argues that these processes are more than mere parts of an opportunistic conjuncture. Instead, their interconnectedness constitutes an integral part of the city’s contemporary urbanisation, being a continuation of the crisis-struck, construction-driven economic models that have historically characterised much of the Mediterranean European Union.
