Now in its fourth edition, the popular International Labour Law provides you with a revised and updated interpretation of the crucial International Labour Organization (ILO) instruments -- Constitution, conventions, declarations, resolutions, and recommendations. It also examines other sources of law, such as the OECD Guidelines for Multinational Enterprises and various model and actual corporate codes of conduct. The first section provides an introduction to, and a brief history of, the founding principles of the ILO and their relevance today. It considers the long-standing -- but still topical -- relationship between international law and economic competition, and situates international labour standards within the constitutional framework of the ILO (which has issued most of them).The bulk of the book is divided into three main areas: the sources of international labour law, the content of international labour standards, and their implementation and effectiveness.
