Bullying is deliberate, unwanted behaviour that causes harm to others, and where the childor young person displaying bullying behaviour knows that their behaviour is or will beperceived as harmful by the child or young person experiencing the behaviour. Bullying isnot accidental or reckless behaviour. The harm can be physical (for example personal injury,damage to or loss of property), social (for example withdrawal, loneliness, exclusion) and/oremotional (for example low self­esteem, depression, anxiety) and can have a serious andlong­term negative impact on the child or young person experiencing the bullyingbehaviour. If the repeated harm is real for the child or young person experiencing thebehaviour but unintended by the other child or young person, this is not bullying but,importantly, must still be addressed under the school’s code of behaviour.
