Here you go AN
'Bullying may be characterised as offensive, intimidating, malicious or insulting behaviour, an abuse or misuse of power through means intended to undermine, humiliate, denigrate or injure the recipient.'
The legal definition is if the behaviour 'has the purpose or effect of violating the complainant?s dignity or creating an intimidating, hostile, degrading, humiliating or offensive environment'.
It is not the intention of the perpetrator that is key in deciding if harassment or bullying has occurred, but whether the behaviour is unacceptable by reasonable normal standards and is unwelcome to the person or people subjected to it or witnessing it.

So whether the person feels bullied is important as opposed to whether the person intends to bully or would say they are bullying.
If you have a look here ACAS has a leaflet for employees about bullying, definitions, examples and what to do.
Hope that's helpful, do you want to explain a bit more about what's been happening?
