You are employed at the UN on the basis of the terms of your appointment. Work at the UN is dynamic and involves a wide range of specialties. Three types of appointments fill the nature of the work and allow the UN to plan and budget effectively for the work to be performed: TEMPORARY, FIXED TERM AND CONTINUING.

Your letter of appointment tells you:

  • The type of appointment you have;
  • The starting date and the time period of the appointment
  • The category of the post (Field Service, General Service, Professional, National Officer) and the level (e.g., FS-7, GS-3, P-2, NO-A)
