Run. Run away. Run as fast as you can.

These people are not your friends. They are not worthy of sane employees. They will never ever react in normal or expected ways to anything you do. And if you stay you will have to deal with poor and irrational behavior 24 hours a day. There is no relationship here that is worth saving.

NO JOB is worth that kind of crap.

If they treat people that badly, even having their company on your resume may be a detriment to your future. They probably have a list of disgruntled employees, vendors, subs, and clients a mile long. You don't need to be a part of that.

Get out now!

Good luck.
