No one will deny that labour standards comprise a necessary framework for balanced economic and social development. Yet on a global level such balanced development has not occurred, despite the existence of a rigorous body of international labour law that has been active and growing for eighty years. The implementation of this law devolves upon states; yet many states have failed to honour it. If we are to take serious steps toward a remedy for this situation, there is no better place to start than a thorough, well-researched survey and analysis of existing international labour law - its sources, its content, its historical development, and an informed consideration of the barriers to its full effectiveness.
