Pros
UPS provides great entry level management opportunities. WIth relative ease one can achieve p/t management promotion and begin to develop skills that will assist you as you transition into your career.
Cons
UPS expects p/t supervisors to permanently stay in their positions. Many employees are lured out of the union into p/t supervisor status only to discover years later that this was an unwise choice. If you have no desire of attending college do not accept a p/t supervisor position as this will almost certainly guarantee that you remain a p/t employee indefinitely. Also, many high seniority union employees make terrific wages while f/t management receives mediocre compensation juxtaposed to the extended hours (60 +) work weeks they endeavor.
