Harassment is any improper and unwelcome conduct by UNDP personnel against UNDP or external personnel that has caused, or that might reasonably be expected or be perceived to cause, offence or humiliation. Harassment may be present in the form of words, gestures, electronic communication or other actions that annoy, alarm, abuse, demean, intimidate, belittle, or cause personal humiliation or embarrassment to another, or cause an intimidating, hostile or offensive work environment. It includes but is not limited to harassment based on any grounds, such as race, religion, color, creed, ethnic origin, physical attributes, gender identity, or sexual orientation. Harassment will often consist of a series of incidents, but it may be brought about by a single incident only.
