There may be more people in management at UP with degrees from known diploma mills and other inflated credentials than at any other company of equivalent size and value. Here's a quick guide to determining if your manager's qualifications are actually worth the paper they're printed on (especially in the mechanical department):
1) Is his/her degree from an accredited university? If it isn't from a well-known state or private university (UNO, Iowa State, etc.) then it probably isn't.
2) Is his/her degree from a for-profit university? If it is from the "University" of Phoenix, DeVry, etc., then it isn't worth the cost of the paper it was printed on.
3) Is he/she inflating their credentials? A one-week seminar at a business school is not the same thing as getting an MBA there. They tell you that before going to the course. Remember that a certificate from a university isn't a degree either.
If you see any or all three of these things happening with a manager, there's a good chance that they're unqualified, and that should concern you.
