A common system of salaries, allowances and benefits is applied by the United Nations,
its affiliated funds and programmes and most of its specialized and related agencies. The World Bank Group and the International Monetary Fund – although specialized agencies of the United Nations – are not part of the common system.
The common system applies to over 100,000 staff members serving at close to 1,000 locations. Common personnel standards, methods and agreements are designed to avoid serious discrepancies in terms of conditions of employment, avoid competition in recruitment of personnel and facilitate the interchange of personnel.
