Demographic change is changing the face of working life across the EU. The increased demand on a shrinking pool of workers to provide for the social needs of an ageing population is leading to increases in the employment rate of older workers and a lengthening of working life. Policy reforms have – on the whole – focused on raising the statutory retirement age and providing financial incentives for older workers to remain in work beyond retirement age. However, a range of other factors also influence workers’ decision to continue working into old age – including health and well-being, work–life balance, career prospects and job security, and working conditions such as autonomy, hours of work and psychosocial aspects of the workplace. This report analyses these factors in depth for the 28 EU Member States, using data from the latest European Working Conditions Survey (EWCS 2015) and in the context of Eurofound’s concept of ‘sustainable work over the life course’.
