answer:I’ve known two people that were very happy working at Fedex. Been there for 15–20 years. USPS because of the post office union seems to be a tough nut to crack. As I understand it, the post office is all about seniority, and since they’re trying to downsize, it would be a very difficult gig to get into for any length of time. UPS, I have heard, is a great place to work but very very tight on discipline and performance. So you would have to be really good to keep a job there.
