> If you are in a small private company and the company owner is the bully then you probably have to just accept it or go to your boss and say "this stops now or I'm leaving" with the expectation that you will infact be leaving.
Yep.
> If you are in a large corporation, there are plenty of policies in place. Talk to HR and find out your options, even if it is your boss, you will have a bosses boss or even his boss whom you can take it to. Large corporations do stuff like this pretty much by the book because the alternative union or litigation action isn't worth it for them
Depends on the organisation. Some large organisations have HR departments that do what they're told, no matter what bollocks they put in their policies.
> Collecting evidence is a good idea. Contacting your union if you have one is a good idea.
Agreed.
> You do have the possibility of taking legal action but I'd guess that unless the bully is doing something patently outrageous like nailing rotting goat skulls to your front door, this is probably just a doorway to a long, tortuous, expensive and ultimately non-worthwhile life. You can always talk to citizens advice if you think you want to go down the legal route though (or if it is outrageous as above, just phone your local police station and arrange a time to give them a statement so they can open a case).
Or kill their pets and subtley let them know it was you. (Hypothetically speaking of course).
