advancement

I've been driving package for 2 years now. We get paid well, (still waiting 2 years for max pay) but I want more if possible. Center managers seem to do well. How do you get there? Or any other career advancement advice or ideas are appreciated. Thanks

So everybody I've asked at the Lexington hub has given me such a mixed variety of answers to this question that I am really unsure of who to believe. On the 3rd of December I passed the part-time supervisor test. Now I'm just simply waiting to be notified of when I get this position. How long...
