The book "Well-being at and through Work" collects a selection of the contributions presented in the Fourteenth International Conference in commemoration of Prof Marco Biagi. The Conference was held at the Marco Biagi Foundation, University of Modena and Reggio Emilia (Italy). The essays, in English, investigate from manifold perspectives the possible implications of changes in the work organization and employment schemes for the well-being of individual workers. In legal terms, the topic stimulates a reflection on the values that lay behind the regulatory choices and the current trends in collective bargaining. "Well-being at and through Work" is devoted primarily to academics and experts in the field of labour relations who wish to analyze the most relevant issues related to the promotion and the protection of workers' well-being by means of a comparative and interdisciplinary method. This is a co-publication with G. Giappichelli Editore.
