Yes it white collar pay for blue collar work but it's still manual labor that beats on your body daily. Most drivers that have been with UPS a long time have knee, hip, shoulder and or other joint problems that will never go away even with replacements.
I want to work smarter and not physically harder as I get older....
No most drivers who have been at ups a long time know how to work smart and play the game so they don't need those things. When you've been a driver for a long time you don't work physically harder, you work smarter.
You want to work "smarter" yet you're going to be an on road?
Have you not been paying attention to the ups management culture of the last 10 or so years?
Why do you think the old management guard is retiring in droves?
Like rats jumping off a sinking ship.
