“Lost Millennials” focuses on a regularly neglected group of the generation of Millennials: young people aged 25-29 who are neither in employment, education, or training (25+NEETs). The main objective of the initiative is to contribute to the successful economic integration of a generation which started their working life shortly after the economic crisis of 2008. Experiencing uncertainty and lack of security for work and well-being, Millennials are more likely to be inactive or in precarious jobs. This issue will be addressed through research, capacity-building and know-how exchange events, and engagement of policy-makers through the key principles of realistic planning, strong cooperation, diversity as an asset, flexibility, and consistency. “Lost Millennials” is a transnational effort, uniting organizations from 13 European countries: Bulgaria, Hungary, the Czech Republic, Greece, Malta, Poland, Romania, Slovakia, Spain, Austria, Iceland, Finland and Norway.
