The International Labor Organization, created by the Treaty of Versailles in 1919, is the oldest of all international organizations, and the only one whose members include not only states but also representatives of employers and workers.
Its constitution enjoins it to prevent "the non-adoption by any nation of a truly humane system of labor (from) obstructing the efforts of other nations to improve the lot of workers in their own countries". It is therefore incumbent on the ILO, not to impose the same labor regime on all States, but to support the efforts of those who wish to improve the lot of their workers, and to prevent these efforts from placing them at a disadvantage vis-à-vis countries that refrain from doing so.
To this first mission, the Declaration of Philadelphia (1944) added a second, namely to ensure that "all economic and financial policies and measures" are such "as to promote, and not to interfere with ... the right (of all human beings) to pursue both their material well-being and their spiritual development in conditions of freedom and dignity, of economic security and equal opportunity".
These constitutional principles have lost none of their value or topicality. On the other hand, the conditions under which these two missions are carried out have changed profoundly, insofar as work is today the scene of three major upheavals on a global scale, all of which present challenges: a technological challenge, an ecological challenge and an institutional challenge. To meet these challenges, we need to understand the extent and significance of each of them, and analyze them through the prism of the diversity of experiences and cultures confronting them.
Contributing to this dual task will be the subject of a Centenary Book, to be published by Editions de l'Atelier in autumn 2019 with the support of the ILO. To give this work unity and coherence, its prospective authors will be able to present and discuss their respective contributions, at an international colloquium, to be held at the Collège de France on February 26 and 27, 2019. The main lines of the symposium program will be as follows.
