This paper is concerned with the evolutionary process of the global governance of labour migration, which has led to the progressive privatisation and commodification of international labour mobility. The focus is on the effects of such change on working conditions for migrants. In particular, the analysis is concerned with legal conceptualisations of labour mobility and their repercussions on the normative process of migration governance. For people on the move, the journey almost always entails sacrifices and uncertainty. The possible costs range from the emotional cost of separation from families and friends to high monetary fees. The stakes can include the physical dangers of working in dangerous occupations, or even a risk of death, such as in the case of illegal border crossings. Nevertheless, millions of people are still attempting movement, facing these costs or risks, in order to improve their living standards and those of their families. The implications for international human rights law are striking. Thus, attention is drawn to the human rights of all migrant workers, and more specifically to the protection and development of basic labour rights in the framework of international organisations. Ultimately, the main point of this study is to evaluate to what extent the freedom to choose where to work and to do so in decent conditions is a current legal reality at both the national and international levels.
