I'm not sure what hell these jobs are that turns drivers into such shitty people, but I feel pretty confident that it is the system turning them into shitty delivery drivers rather than exclusively shitty people applying for delivery jobs.
Some are amazing, mail is delivered perfectly, etc.
Others cannot for the life of them match number to address, and it doesn't seem to matter who is delivering as the attitude spreads across the office.
I think a huge part of this is missing actionable feedback messages.
If USPS/UPS/FedEx had better channels for "my mail was screwed up" reporting, to a granularity necessary to isolate bad branches, I think things would clean themselves up.
As-is, customers learn to live with it and the mothership is unaware the branch is screwing up.
No more anything like this "I sometimes get delivery drivers getting pissed off at me (for some reason) that the code doesn't work. You can cut into any their speech with "English, m****r, do you read it?".
Gig workers quite possibly don't, or at least it's a significant effort for them to.
