The entity responsible for administering the day-to-day operations of the United Nations (UN) is the UN Secretariat, led by the Secretary-General. The Secretary-General serves as the chief administrator and is in charge of the executive oversight over the UN, handling leadership, diplomacy, public outreach, and overseeing numerous administrative duties. The Secretariat, which consists of thousands of international professionals, is tasked with managing the multitude of special agencies, such as UNICEF, WHO, and UNESCO, among others, to maintain international peace and security.
The General Assembly and Security Council are two main institutional bodies of the UN that work in conjunction with the Secretariat. While the General Assembly primarily deals with policy deliberation and electing members to various bodies within the UN, the Secretary-General and the Secretariat oversee the daily administrative tasks.
