The global challenges resulting from economic, demographic, ecological changes have led individuals to evaluate the advisability of creating new work identities, adopting a perspective based on social justice and sustainability. In this sense, this book examines the ways and the means through which the principle "labour is not a commodity" has been developed and the practical implications thereof. It will serve to help academics and practitioners in a number of fields to understand the ongoing socio-economic changes and the impact of globalisation today, and to analyze the role of public institutions and private stakeholders operating in the context where this principle is implemented.
