My experience and ONLY my experience:
Started UPS when 31, after 10 years of heavy equipment. Already back problems. Hired as feeder driver, well, they said we don't have position now, "Would you be willing to do delivery until there IS position?". Me: "Sure, why not, just to get my foot in the door". How bad can it be, huh?
You know the rest. Had to do package car for 3, full years, til feeders came up, then spotty for the next 5, in other words, back and forth from PC to feeders. Finally was able to stay after 8 years with company but here, HERE, I say, lowest senior drivers had to do coverage. Did that for another 5 til I could bid on something...ANYTHING.
Was married, with one kid. Worked nights or afternoons the rest of my career, even sleeper team for 5. Sorry but she had to endure that after some major demands from her at the beginning of our marriage that didn't work out.
No experience? No prob. They will teach. They will help you get yer CDL.
Retired after 32 years and don't regret my decisions. To me, was actually easier on my back. I'd say give it a try, but look at all the quirks of the job there. Talk to other drivers to see if it's for you. Good luck and let us know, please.
