Wheels, of course bullying isn't ..."all about perception". It is a complex issue like most human issues. Some people are quite simply deluded, where is the perception there?
I too have had experience of dealing with allegations of bullying and it is exactly as Dave says inasmuch as before any allegations are un/substantiated a process of natural justice and investigation has to take place. The "victim's" perception of the situation cannot just be accepted as fact. If we accepted your premise we might just as well go back to burning people who we think are witches because it is our "perception" that they are and also because they wear pointed hats and like black cats.
If it's my perception that I'm tall and slim when I'm actually short and fat then which one is true ?
Come on Wheels you're in a hole, stop digging, and oh, apologise to Councillor Kev.
