The traditional roles of employees and employers increasingly lose clear definition. Every individual forges his own destiny and performs, it seems, with virtuosity on the keyboard of self-management. Between the autonomous freedom, an enormous degree of performance concentration and biographical uncertainties, new forms of work emerge - but also new phenomena of stress.How do people deal with this while staying healthy and fit? How can one handle this change from a societal point of view? And how we react to these challenges as individuals? The contributions to this volume provide answers.
