Hey man thought I'd chime in here as I have plenty of experience when it comes to games with employers. Bottom line is you gotta look out for number one, don't give them any ammo to use against you, and don't let them rent space in your head. Its tough sometimes but we, as musicians, are a different breed then everyone else out there.
Take out some of this frustration on your instrument. Just make sure you have a recorder running when you do. Hope it all works out.
Peace
