Pros
You will lose weight and get fit. The work is hard, but the physical benefits and pay help offset the difficulty. Plus, there is room to grow in the company if you are dedicated enough.
Cons
Our hours kept fluctuating which made it difficult to figure out an average weekly salary. (However, the company was very timely about delivering their paychecks to employees.) I was promised to work five hour shifts, but as time went on that was reduced to three and I sometimes worked less than three hours a day. Once, I was asked to not come in because there was not enough work. Even the full-timers were getting their hours cut with some complaining about "two-hour lunches" meaning that their (unpaid) meal break was extended to two hours instead of the normal (and state-required) 30 minutes. The only time I was able to work five hour shifts was during the holiday rush in December.
