Figure out if you are in a "one party" state for recording purposes. If you are, RadioShack sells a very small digital voice recorder. Then, tape his comments and notify the Union and possibly consult an attorney. Personally, if his comments and actions are as egregious as you've described (and can prove it), I wouldn't even bother with the Union. It must be a very tough and frustrating situation to experience. Most importantly, whether she is able to record or not, she must document, document, document. She needs to start a notebook detailing times, dates, witnesses, comments, etc.. If she has written details of numerous encounters with specific times of day, dates and converstaions, they may take the situation more seriously - or not. Either way, it can't hurt to start a journal. Good luck.
