The purpose of this volume is to describe the impact of the increased demand for flexibility on employees and its impact on their individual work life trajectories and health. The volume offers concrete examples of interventions aimed to find innovative ways of sustainable work careers for today's workers. We focus on the school to work transition, job insecurity, job loss and re-employment and retirement. The interventions described offer strategies for implementing support in employment contracts, increasing preparedness of individual employees with public education programs or developing work arrangements and support systems in work organizations.

Vuori's research group has been involved in prevention research, large field experiments (RCT), implementation and country-wide dissemination of group interventions into service systems for enhancing coping during these difficult occupational transition phases.
