I'd say that definitely is bullying as he's singling one person out for humiliation.
Thanks for responses. I got interrupted and didn't quite finish what I was trying to say.
I dont know why he has picked on her as it seems, although not meant to be, all those learning are female.
But I think he can spot she isn't that confident and rarely speaks up in public.
But has formed a few supporters from her muttered responses she whispers!
But suspect there are many situations where for some reason a man is in charge (well this is normal of course) and choses to use it to be a tormentor in a cowardly way because they know their position allows them to do it.
But going back to the more professional situation, there is of course the competitive aspect. Rivalry.
And not saying women cant be competitive, but some men can be a bit over the top about it. And when you are part of television programme watched by huge number of people, I suspect some lose perspective. ie cant see it for what it is intended to be, enjoyable family entertainment, where celebrities are willing to put themselves forward to fail, make a fool of themselves, etc., etc..
