Welfare - Bullying
Bullying is repeated verbal, physical, social or psychological behaviour that is harmful and involves the misuse of power by an individual or group towards one or more persons. It can have long-term effects on those involved. 
Some conflicts between children are a normal part of growing up and are to be expected. These conflicts or fights between equals and single incidents are not considered bullying, even though they may be upsetting and need to be resolved.
Identifying bullying can sometimes be difficult. Bullying is often conducted out of sight of teachers, and children may be reluctant to report bullying.
Cyberbullying is a term used to describe bullying that is carried out through internet or mobile device technologies. Children who are cyberbullied are also likely to be bullied face-to-face.
Harassment occurs when someone is made to feel intimidated, insulted or humiliated.
The National Safe Schools Framework NSSF (see attached PDF doc) provides schools with a set of guiding principles and strategies to help them provide a safe and supportive school community for students and the broader school community. BULLYING NO-WAY! and BULLY STOPPERS are websites which also provide information and resources on Bullying.
