appreciate thatI feel for you. It is a stupid policy to blame us when the other driver is clearly at fault.
I have been told many times that UPS judges avoidability not fault.
Their intention is to make us more aware of every possibility, which is fine until it costs you your job.
The same thing happened to me 26 yrs ago and it did make me more aware of the cars parked around me.
It didn’t cost me my job and I haven’t had as much as a scratch on my pkg car since, so it doesn’t mean you will be an unsafe driver.
I hope they give you another chance.
