Curious who in the USPS isn't delivering on Sundays when their little trucks are everywhere on Sunday. Still comparing this to Uber is a bit absurd. Uber is contract for hire/etc - there is little more needed than being clean of record and signing up. Good luck getting into the USPS. Plus with Uber and similar your workload is what you make of it.
So while Uber is on many people's shit list we must not make comparisons which are in effect meaningless. Instead we need to compare them to direct competitors, the other for hire services and other private delivery options on the low end. The higher end open delivery might be FedEx Home, FedEx and UPS are similar to USPS, you have to first get past the hiring process and live under someone's schedule and tight rules
New carriers are "temporary" until a route is open. They do the sunday and holiday deliveries. They get fired every 360 days and after 5 days they get rehired.
Thats why i said "lucky" there is a two tier structure
