Bullying wrecks lives and affects people in all kinds of ways.
It can be anything from name calling, being intimidated, left out or cyber bullying to more serious stuff such as being forced into doing something you don't want to or acts of physical violence. It can even happen in the workplace.
It is not always a crime. However, it is still distressing and needs to be dealt with. It is always advisable to speak with a parent/carer, teacher or other trusted adult or friend. It is prohibited in the workplace by various laws. When it becomes criminal, the police should be informed.
