Collective bargaining between employers and trade unions has profoundly changed working conditions in companies around the globe. But why do we start work at the age of 10, 16, 18 or 24? Why do we work 6, 8, 10 or more hours a day? This book addresses the process of working time regulation over the last twenty years, evaluating the activities of trade unions, employers, and the State. This book draws connections between time and markets, places these transitions in their historical contexts, and illustrates the importance of this movement crossing borders and cultures.
