Contingent Workers' Voice in Southern Europe investigates the manifold challenges posed by the continued expansion of the platform economy, the rise of non-standard forms of employment, and the diversification of work identities. Leading authors explore the potentialities and barriers for collective protection and representation of contingent workers in the platform economy, based on the experiences, needs, and aspirations of workers in Italy and Spain. Chapters undertake in-depth analyses of a diverse and innovative variety of initiatives for the protection, organization, and representation of contingent workers. The book ultimately constructs a framework to interpret the evolution of contingent workers' experiences, allowing trade unions, social movements, and cooperatives to develop organizational and representative practices that better respond to their needs. This incisive book will be of interest to researchers and advanced students of sociology, international relations, political science, and labour law. Its practical insights will also enable trade unionists, activists, and policymakers in the field of labour relations to make informed decisions and identify possible avenues for development.
