There's a Respect And Dignity At Work Act? Seriously? Bloody hell, what's the world coming to?!
Anyways, that example isn't bullying, that's the boss being a ****. Agreed I wouldn't particularly like to be on the end of it, and I might even kick off back (and have done in the past when someone's spoken to me like that), but it's hardly bullying. The way I see it you've got three choices: You can either go up as a team (and I mean all 12 of you) and tell him you're not happy with his attitude, or you can accept that the bloke is a bit of a pain and be grateful you've got a job but keep an eye on other opportunities, or you can quit now and find something else.
Umm, so how does you breaching your contract put you in a better position? Work your notice but barely work IYSWIM, that's what everyone else does.
