Generally you would want to write down any company infraction, including cunty/bitchy/hostile events towards workers (yourself included), over a period of time.  Doing this establishes an evidentiary chain of behavior that can then be used in a complaint to the owners/HR.  And if they refuse to fix the issue, a suit against the company for hostile work environment. It sucks, and it is a really difficult thing to do, but letting such behavior continue only adds to the problems.
