Bullying is a misuse of power in relationships expressed through repeated verbal, physical and/or social behaviour that causes physical and/or psychological harm. Bullying can involve an individual or a group misusing their power over one or more persons. Bullying can occur in person or online, and it can be overt or covert. Bullying of any form or for any reason can have long-term detrimental effects on those involved. Bullying can occur in many ways, face-to-face (e.g. pushing, tripping, name-calling) at a distance (e.g. spreading rumours, excluding someone) or through information and communications technologies (e.g. use of SMS, email, chat rooms).
