Low Fuel is correct...it would not be unexpected to see mesa staff "posing" on the airline forums to attempt to identify and record the statements of unhappy employees (they are legion).
The work environment is almost unbelievably bad. It would take me an hour to tell all of the stories. Suffice to say that what you read on the internet is probably not as bad as it really is, my personal experiences led me to trade a no-commute domicile and a captain upgrade to start over elsewhere. As a military guy, you can do FAR, FAR better, and should never think of the word "mesa" again.
