Problem is the automation, not the employees- USPS top management has closed lots of regional sorting centers so now a package going 5 miles between towns goes 500 miles to a massive sorting center and back. Get a misscan somewhere in there and the package can take a cross country detour. Worked for USPS for 15 years and the workers had to do a lot of workarounds to avoid these mail detours, for example we would manually route mail directly between those adjoining towns so time critical stuff like notices, church bulletins, and ads for local businesses made it to local mailboxes before the event.
