UncleJT, I am not going to insult your intelligence by telling you to do your helper job as best as you can. The trick is what you do
after 12/22. Keep calling and offering to come back and work. Know the names of at least two persons at the HR department. Write thank-you cards to your driver and the HR gurus. Call them weekly and politely remind them that you are ready to come back on a permanent basis. And have a backup job that you can go to for January and February. If you are lucky, there may be an opening in Jan. or Feb. (someone going off to school) and you can get in before the true bulking of the rosters(early spring for the most part.)
Even if
UPS hires you, remember that you will be at the bottom of the seniority food chain.
UPS can only guarantee you 10.5 hours a week, so keep that secondary job until Xmas '08 if possible. Also make friends with the persons in your new workgroup who have the MOST seniority. Knowing when these UPSers want a day off can spell extra hours for you if you are the first to call your supe on that friday without their most senior guys. And once you learn your workarea well( usually about three months) try to learn the workarea/trucks/package cars next to you.
And don't let your need to please make you forget to do the job safely. You are not going to make a good impression if you cannot come in due to a bad back.
Good luck and keep in touch!
