The aim of this book is to explore labour law’s conceptual and normative narrative. If labour law is informed by the wider political and economic landscape within which it operates, then given the declining prevalence of the post-war model of full employment within a formal welfare state regime, what shape does or should labour law assume in response to the transformation of the political economy in countries of the global North? Correspondingly, what is the proper role to be played by labour law and labour relations institutions in the development process within industrialising countries of the global South, where informal employment has long been, and remains, the predominant form? Drawing on the expertise of leading labour law scholars, this collection addresses those questions by examining the growth and continued prevalence of informality. Offering research that is both empirically grounded and doctrinally astute, the book explores the changing character of labour law in the global North and South.
