Get out now, I started a job a few year's back now, I was there only a few day's and I realised how bad the environment was and should have left, however I needed the money and didn't want to be a "failure" again so I stuck it out I think for five or so month's, I nearly died as a result of it. I couldn't tolerate the crap that went on and nothing was done about it, the way we were treated/spoken to, the hour's, etc. I learn't a valuable lesson. If you can try and find something else - your life/well-being is far more important than a job.
