I agree with Vette in the "Life" aspect (having more skills). But the more you know at UPS, the more you get abused. When I was a parttimer, I knew how to do every job from smalls sort to fuelers (aka carwash to some of you). Man, I got bounced from job to job since they were all in same pay scale. When I learned to drive package cars. I got quite the route knowledge under my belt. What did that give me? WAY too many route bouncing. So, in UPS, too many skills killed me. But in reallife, has saved me thousands of dollars doing fix it's myself.
