The International Labour Organization (ILO) is the United Nations (UN) agency with responsibility for labor issues. In 1969, the quality of its work was recognized with a Nobel Peace Prize, awarded for its relative success in achieving its mandate when compared to most other international organizations. In giving the award, the Nobel Prize committee recognized the difficulty of improving employment standards in a complex global environment. At the time of the award, it was noted as a substantial achievement that the goals of the organization had been met in most developed countries. It was also noted that the future role of the organization would lie in continuing its work to help shape standards in the developed world. As of May 2009 a total of 183 countries, almost all of the countries in the world, were members. These elements, together with the ILO's long history, its international mandate and profile, and the broad level of participation and comprehensive membership, combine to make it a significant organization involved in the creation of an international framework of employment rights and minimum standards.
