Report all incidents when they happen, do not wait for the end of day.
I was once excused of causing great damage to a PC, a Fed Ex driver saw it happen, called it in to their sup, who was a friend with my sup., who called me.
Luckily I was on another air run that night.
The bad driver had gone under a low hanging RxR bridge and taken out the entire windshield. When bad driver returned to the building, swapped out packages into another PC, before unloading onto the air belt. Then left for the day. Bad driver never bothered to sign off on any vehicle used , nor input PC Number and mileage into DIAD every time while working.
Yes, bad driver did get fired and then sued.
Bad driver did not see witness, who saw bad driver hide damaged PC, and reported it to Automotive while Bad Driver was walking out of the building.
