The aim of this project is to shed light on the relationship between longer working hours, health, and the support provided to relatives who are losing their independence. This issue is a matter of public policy in each of the countries involved in this project (France, Germany, the United Kingdom and Denmark). The aim is therefore to shed light on the choice of working hours, and how this decision affects the health and well-being of older people, as well as how taking on the responsibility of caring for elderly relatives may affect the carer’s ability to work for longer. This study will take into account the institutional aspects of the countries under consideration, as well as the implications in terms of inequalities.
