Pros
UPS offers stability because the company is stable. The benefits are good, however they were better before they went public, at least for management. Pay is decent unless you figure out what the hourly pay would be and then it isn't that good. Good retirement benefits........ if you live long enough or survive the hostile environment the last 3-4 years prior to reaching the magic age.
Cons
If you are considering moving into management think long and hard. Here are the reasons why: If you are in management you do not have any protection. Management has a very high divorce rate (per HR prior to moving into management) and for a good reason. UPS expects management to work 12-14 hour days and not just during peak. You will get little training. Based on experience, it appears UPS promotes people without any proven people or leadership skills. Poor performers are moved to non-operational positions which is like a reward due to the shorter, more humane hours. And if you do well in an operational position you are condemned to operations, even if you have voiced other interests.
