Solobiker - you have a marketable skill. Other offices / clinics will have sick leave, vacation time too. They should be paying you the earned vacation time when you leave, so if nothing else, bank the money to fund a trip at a later date.

Save your sanity, dignity, and credibility and leave these malcontents.

I left NorCal because of a bad supervisor. One of us had to go, and she wasn't worth going to prison over. Was much happier, and saner after the change.
