Pros
You don't need to have a fancy home to live in because your home is at UPS. You get to be a slave driver, and you get to fire a lot of people.
Cons
Your job is always under threat. Lots of unhappy people that want everything but are unwilling to work for it. Lots of turn over among management. It's hard to work for a customer that has a better compensation package then your own. I say fire your boss and go work for your customer, then you can boss your boss around :) and make bank doing it! If you want to work hard and only do ok in life work at UPS. The Golden years are over, the growth stage of stock splits and IPO is over. The age of growing liabilities, and competition by goverment postal systems will slowly erode the core business of UPS.
