Several major transformations have characterized the world of work in recent years. Those transformations follow different patterns in different countries, yet their dynamics are so interrelated that it is often hard, if not impossible, to distinguish the causal relationships among them. Technological advances, globalization, old and new media, demographic changes, and new production and economic systems are all key factors acting on this ongoing transformation which is impacting both the world of work and society as a whole. In the spirit of Karl Polanyi, the well-known scholar who described the rise of market-based societies, we are led to wonder if we are witnessing a new "Great Transformation of Work", on such a scale that it might change the very meaning of work in our society, and even its anthropological connotations. Accordingly, this volume investigates and discusses the different aspects of this transformation from a comparative perspective. In order to propose better solutions to cope with these changes, it is necessary to analyze their ongoing dynamics. Lawmakers, unions, scholars and practitioners are all called to do their part in order to achieve the goals of sustainability and fairness of our economic systems.
