The relationship between unstable work careers and family transitions into adult life can vary according to the personal circumstances of individuals, as well as the welfare state system of the country. Drawing from interviews and survey data across the EU and the UK, this in-depth study explores how worker instability is perceived and experienced, and how this ‘perception’ in turn affects individuals’ economic and social situation. Using intersectional analysis and a unique focus on different life stages, the authors identify groups who are more prone to labour market risks and describe their relative disadvantage. This powerful study will inform policy measures internationally in several social domains related to work, employment and society.Drawing from interviews and survey data across the EU and the UK, this in-depth study explores how worker instability is perceived and experienced, and how this “perception” in turn affects individuals’ economic and social situation.
