Why do bullies do what they do? Shivaani Kohok explores the reasons for bullying behaviour. She talks to two bullies who explain why they do what they do – in one case, a young woman realised how the online comments she had posted about others who had previously bullied her were in fact another form of bullying behaviour.

Shivaani talks to experts who provide insight into the different types of bullies including "victims" and "ringleaders". She investigates cyber-bullying, bullying in the family, as well as workplace behaviour where bullying bosses can turn on their highest performing managers.
