If you have no drive to promote and move up with in a company and are fine with waiting your turn behind people that are not qualified to do the job than this is the place for you. if you enjoy gosiping like a group of old woman, this is the spot, and if you like losing over 40% of you pay to things like union dues (for what i'm not sure cuz they always do terrible deals) and benefits which some of the most i have ever paid for, a retirement plan with no op-out option, and of course taxes than hay this is a dream job.
Pros
almost impossibly to be fired after probation period, lots of down time.
Cons
Low pay, Pay raises not enough, expensive benefits
