Some drivers have to unload their trucks depending on the load and the receiver. For multiple LTL (less-than-truckload) loads the driver might stop at multiple facilities and unload a handful of pallets at each.

This would be more likely for smaller-format discount retail like, e.g., the Dollar Store or a restaurant supply chain.

I have family that works for a food distributor where their drivers get to restaurants, unload the truck, stock the items in the fridge/shelves, and take additional orders from the customer before they move on to the next delivery.

Local drivers. They follow a different process than long-haul drivers do and are way more likely to unload their own trucks.

It was sarcasm. Lots of truck driver jobs are hands-on.
