The Guidelines are organized around eight key Principles corresponding to the course of a staff member’s contract. The accompanying diagram represents the principles visually. Each principle has supporting Indicators and Comments and Case Studies designed to assist the reader to more fully understand the concepts that the principles are based on and how they can be translated into practice. The principles and indicators are intended to apply to both international and national staff and to both office and field staff, recognizing that adjustments may be necessary to take account of the unique needs and characteristics of each group and of the organization. They constitute a tool for learning, reflection and planning rather than a set of rigid rules or solutions that are applicable under all conditions.
