This open access book explores the EU regulatory framework to measure in-work poverty and reduce its impact on different groups of workers in the labour market.Its innovative approach links the enhancement of social rights with the full realisation of EU citizenship entitlements and values. For almost two decades, EU countries have experienced rampant inequalities as well as the varied spread of in-work poverty, both around Europe and within national labour markets.Without the realistic prospect of EU citizens earning a decent living, the substantive content of EU citizenship itself could be put in jeopardy.Following an in-depth scrutiny of the main policy options at both EU and national levels to reduce the number of working poor, this invaluable resource provides a theoretical reflection on the role of legislation and socio-fiscal welfare in contemporary labour markets.The editions of this book are available open access under a CC BY-NC-ND 4.0 licence on bloomsburycollections.com.
