The degree is not a requirement UPS wide. That is just what some Div. and Dis. Managers want. Most don't care as long as you are the one they want for the job. Do not let the talk in this thread discourage/scare you. Even if your Div. Manager holds a degree requirement to be of the utmost importance, he/she could be gone by the time your progression really starts to matter.
Oh, and going FT driver to management is almost guaranteed. Even though they want it, UPS CANNOT get enough drivers to move to management. The drivers see the time the sups and mngrs spend working and what they get paid. Then they see their own pay check, hours worked, and union protection. Simple answer for most of them: no.
If you want FT sup, then go to part time sup. In most areas, it is the quickest route. Everyone will tell you things like "all PT sups quit" and "they all get left behind." The fact of the matter is that a majority do. HOWEVER, you need to keep in mind that these candidates usually lose their ambition and do not want it anymore. It usually is not the case where a candidate toughs it out (however long that may be in your area) and then gets left behind.
