Pros
The best reason to work for YBUSA would be when you have too much free time on your hands and too much money in your pockets. Working there is similiar to charity work. Whenever you look at the hours expected in comparison to the pay paid, you would be better off working at Wal Mart or a convenience store. I do think that working there for a short period of time (which is pretty normal at YBUSA because of the high rate of turnover) would be valuable to help a person know exactly what they do not want to do for a career.
Cons
They OVER PROMISE and UNDER DELIVER on a regular basis. The average rate of pay for someone on sales ends up being 13-14 dollars per hour by the time that you factor in how much is expected of you and the "real" amount of money made for doing the job. The turnover is unbelievable! I worked in the Tulsa, OK office which had turnover of 100% over a period of two years. Their benefits are not very good and they push their stock purchas plan on everyone. The problem is that their stock price is down something like 80% over the past year.
