Pros
There is a sense of pride in doing the physical work. They do offer great benefits if you make it through the gauntlet. I have great respect for those that just put their headphones in and ignore incessant talking down.
Cons
No matter how much you are willing to adjust and do it is never enough. You can give it 110% and they will demand 120%. Give the 120% and they demand 130%. Almost comical when being barked by an extremely immature adult-child supervisor. The benefits are intriguing and can really be a good thing but you really have to weigh your dignity vs benefits. The pay alone is ridiculously small compared to the large demand always put on you. If you are the type of person that enjoys waking up at 2:30am and going to work for a mere 3 hours and getting paid a lousy $20 after taxes and other deductions all while having an unqualified supervisor treating you like garbage then this is the job for you!
