Very Friendly working environment, you meet people from different nationalities and cultures.
Plus the humanity side of working with UNHCR by helping other peoples.
Cons
Not following the safety procedures specially for those who work in the field may lead to series accidents.
Human Resources takes a highly specialized approach to talent management. In that you cannot really change functions easily in UNHCR. You have to hyper-specialize in one area. So if you are a protection staff, you tend to burn out from trauma without an internal mechanism to alleviate the burnout. The higher you go in UNHCR, the crazier you become.
