This report is part of a joint studybetween the European Commission (EC), the World Bank, andtheOrganisation for Economic Co-operation and Development(OECD). It aims to inform activation and employment supportand social inclusion policy making and programs through animproved understanding of labor market barriers. The peoplewithin and across countries characterized as labor marketvulnerable are not all the same. Different life situationslead people to being unemployed, inactive, or precariouslyemployed. Various personal constraints may induce people totake temporary or precarious employment, work a reducednumber of hours, or earn very low incomes despite beingengaged in full-time work. All of these are considered thelabor market vulnerable, and a better understanding of theirdifferences and similarities is essential to successfullabor market inclusion. Governments need to know who thelabor market vulnerable are and what barriers keep them outof work or in unstable employment. This information willhelp countries meet the inclusive growth priorities of theEurope 2020 Strategy (EC 2010) and the European Pillar ofSocial Rights; it also aligns with recognizing the potentialnegative impacts of labor market vulnerability on long-term growth.
