The foundation of the International Labour Organization is the off spring of a reform project to improve labour conditions in the face of revolutionary movements during and after World War I. In its 100-year history, the ILO has created a comprehensive system of minimum international labour standards largely laid down in Conventions and Recommendations, together with a supervisory mechanism and technical assistance for the application and control of the norms. The ILO norms are universally valid, independently of a country’s level of development, culture, tradition, and category of worker or enterprise. Conventions classified as fundamental are rated as human rights. They have to be respected and promoted by ILO member countries independently of ratification. ILO labour standards are directed to set an effective floor to wages, hours of work, conditions of employment and social services for all countries engaged in international competition in order to prevent social dumping and achieve fair and stable globalization. The relevance of the standards has grown with the successive stages of global economic interdependence and integration, driven by multi-national companies, cross-national supply chains and trade agreements. Abundant empirical evidence shows that the observance of ILO rules generates economic, social and political dividends.
