International Labour Organization

The ILO was established in 1919 as part of the Treaty of Versailles, which concluded the First World War. Its founding rationale linked lasting peace with social justice and better conditions for workers. It moved its headquarters to Geneva in 1920. In 1946, it became a specialized agency of the United Nations, continuing its work across the postwar international system.

The organization works to advance social justice and internationally recognized labour rights. Its work includes standards for working conditions, research, statistics and technical assistance on social policy and workforce training. The ILO received the Nobel Peace Prize in 1969.

The ILO brings together three groups—governments, employers and workers—in a tripartite system. Worker and employer representatives take part alongside government representatives in shaping labour standards and policy. The International Labour Conference is a central forum for this work: representatives of all three groups draw up and adopt international labour instruments.

This arrangement is intended to bring the interests of workers and employers directly into international deliberations, rather than leaving labour policy solely to governments. The ILO describes itself as the only tripartite agency in the United Nations system.

The ILO's standards address basic principles and rights at work. They take the form of Conventions and Protocols, which are treaties that member states may ratify, and Recommendations, which provide non-binding guidance. Once a country ratifies a Convention, it undertakes to apply it in national law and practice and to report on its application. Adoption by the ILO therefore does not make every Convention automatically binding on every member state.

The organization maintains a supervisory system involving independent legal experts and tripartite bodies. It examines how ratifying countries implement standards, while the ILO can also provide technical assistance. Early conventions dealt with matters such as working hours, unemployment, maternity protection and minimum working age.

Beyond standard-setting, the ILO conducts research, compiles labour statistics and provides technical cooperation on social policy, administration and workforce training. It also develops programmes intended to promote decent work. Its agenda has responded to changing conditions, including unemployment, migration, industrial relations and technological change.

The organization works through international cooperation, national institutions and the participation of social partners. Its standards can guide policy, but their application depends in part on national ratification, legislation and implementation. The distinction between international agreement and domestic practice is central to understanding both the ILO's influence and the limits of its role.
