When I delivered Amazon packages for USPS on Sundays pickers would sort packages into bins by route then us drivers would organize packages from the bins to the truck. I think that was better than having someone else pack because then I could get a feel for where in the vehicle a specific package was, and I could better place them where I could get them (putting early packages closer to the front to grab or way at the back door if it was very large).
I’ve worked for USPS for ~8 months. It’s not just a Sundays thing. I’ve never seen someone else load for someone intentionally. A couple times someone has loaded, then gotten sick or gotten bad news and had to leave. The clerks will sort all the incoming to each route that it goes to, but once it’s in the bin for your route it’s your problem going forward.
