The International Labour Organization (ILO) is a United Nations agency whose mandate is to advance social justice and promote decent work by setting international labour standards.

It was the first specialized agency of the UN. The ILO has 187 member states: 186 of the 193 UN member states plus the Cook Islands are members of the ILO.
The tripartite structure is unique to the ILO where representatives from the government, employers, and employees openly debate and create labor standards.

The Office employs some 2,700 officials from over 150 nations at its headquarters in Geneva, and in around 40 field offices around the world. Among these officials, 900 work in technical cooperation programs and projects.
The main aims of the ILO are to promote rights at work, encourage decent employment opportunities, enhance social protection and strengthen dialogue on work-related issues.
