This comprehensive Research Handbook explores the theoretical and practical integration of decent work to create a more just and sustainable world. It examines decent work as a concept rooted in international labour standards which advocates for fair pay, security and respect for workers' rights. Global experts pair practical examples with theoretical analysis to reflect on contemporary challenges and social issues such as the rise of the gig economy, algorithmic management, climate-related disruptions, poverty and inequality. Chapters engage with diverse case studies from across Africa, Asia and Europe to highlight both universal and regional challenges in achieving sustainable careers and decent work. Contributors also draw from various disciplines to align with broader sustainable development goals and social justice objectives. The Research Handbook on Decent Work is an essential read for students and academics in sociology, psychology, economics and labour studies. International organisations, NGOs and policymakers in employment relations will equally benefit from the pairing of theoretical frameworks and actionable recommendations.
