High end LTL carriers like I work for only hire experience and pay handsomely for it. Breweries, cola companies, basically...big fleets with an image to protect. They are the good ones.
But grocery chains, not so much...to the contrary, they typically contract out the actual movement of freight to third party companies, and some of the guys they hire are challenged to back into the docks at the actual stores, much less actually navigate the truck there through city streets.
A lot of companies won't hire anyone, they just have an army of perma-temps from driver agencies. I worked for a LARGE southern ontario based cartage company that will remain unnamed for 3 years (15 years ago) and was never an actual employee, nor were any of my many coworkers. We all got paycheques from one of 4 or 5 different agencies they contracted through. Of course this gave them the benefit of no strings attached - bring on and get rid of drivers on a whim, you were constantly under their thumb...piss someone off by (gasp!) asking for a day off and you'd be sitting at home for a week because of a "work shortage", then they'd call in another temp to cover your work instead.
It sucked. And it's perfectly legal to this day.
