Which international organization is headquartered in Geneva and works on labor standards?

The International Labour Organization works on labor standards and is headquartered in Geneva.

Founded in 1919 as part of the Treaty of Versailles settlement after World War I, the ILO promotes decent work, social protection, and dialogue among governments, employers, and workers. It is unusual within the United Nations system because it uses a tripartite structure, giving representatives of all three groups a role in its work.

The ILO develops international labor standards through conventions and recommendations, covering subjects such as freedom of association, child labor, forced labor, and workplace safety. Its headquarters are in Geneva, Switzerland. The organization is often mentioned in connection with May 1 labor observances, but it did not create the U.S. September Labor Day holiday.
