When I was a kid (late 60's) , I got a PT job in the afternoon (after school, 16 hours a week) working at a post office in Northern Virginia sorting mail. I recall one of my fellow employees was stealing holiday charity checks sponsored by a local bank every year. They never made it to the bank. Questions ensued, postal inspectors hid in the post office caught him, He was fired and forced to make restitution. Second incident; another fellow employee, and this guy was a friend, was a mail carrier with hours from 7-3. He also belonged to a band who practiced at 330pm. He was a slow carrier always running late,. So at 3pm, whatever mail he had, he threw it away so he could get back to the PO to make it to band practice. Complaints ensued, he was caught and fired. That was 50+ years ago, my guess is things have only gotten worse. That's why I bank electronically today, less people, less problems. Last month, I went to the ATM at my bank to withdraw $200 in an account I keep around 3K in. Insufficient funds, balance $24. Whoa. Went inside spoke to the manager, went through my account electronically, account had been hacked, withdrawals in Jamaica/Florida. Had the money back in my account in 3 days.
