Mobility and Hardship
The Mobility incentive and Hardship allowance are designed to encourage mobility between duty stations and compensate staff for the difficult living and working conditions in some field locations.
Rest and Recuperation
Rest and recuperation breaks are granted to staff members serving in field locations where the work environment is considered to be extremely stressful, isolated, insecure, or lacking the most basic and essential services.
Danger pay is a special allowance granted to staff required to work in duty stations where very dangerous conditions, such as war or active hostilities, prevail and/or where the evacuation of families and non-essential staff has taken place.
A list of countries and duty stations where Danger pay applies is on the UN site.
