The book Labour Mobility in the EU is an edited volume that explores a variety of existing and emerging challenges concerning labour mobility in the EU through the prism of different professions and mobile professionals. A multidisciplinary approach and the utilization of different methodologies pave the path for analytical discussions about the effects of intra-EU mobility, efficiency and equity of free mobility within the EU and multiple implications for individuals, states and national policies. Th­e book opens with a theoretical chapter, which provides an exhaustive insight into the mobility as a theoretical concept, policy agenda and fundamental European value. Next, the complex interplay of multiple and multi-level effects of labour mobility is illuminated through five case studies that outline the dilemmas, paradoxes, impacts and consequences of intra-EU mobility on the case of mobility of healthcare workers, artists and creative workers, posted workers, care workers and highly educated professionals. The contributing authors’ case studies are a result of longstanding scholarly research and active participation in a variety of projects relating to mobility.
