Things are pretty screwy at UPSF right now. If you can afford to weather out the storm, it would be a wise move to plant your feet in with this company before things expand.
A lot of it depends on which area you are looking into working out of. I work out of the Portland, Oregon terminal and I will admit that UPSF is pretty unstable in the West. Even though I am working every day, things are still too uncertain at this point. There have been many runs cut and many lay-offs(with more rumored to occur in the future).
If you are looking for something more predictable or less turbulent--I would steer clear of UPSF for at least another couple of years or so.
I have talked to a few Conway drivers(employees and ex-employees) and none of them spoke very highly of the company. Personally, I am waiting for FedEx to post an driving opening in my area because I would perfer to go somewhere where things seem to be more stable.
