Can I get a new probation officer? Probably not, but consider moving.
Probation offices have a terrible amount of control over the fate of a probationer. Like so many human relationships some people just don’t work well together. Probation officers are people and suffer from the usual human frailties, some enjoy the power of ordering others around and making their lives miserable. If you end up with an unlucky draw and get a PO you can’t work with, or that hates you, what are your options?
First the bad news, you can’t just switch probation officers. Judges don’t care if your PO hates you, they aren’t going to let you change. Probation departments don’t care about customer service, they aren’t going to let you change. Prosecutors really don’t care. So the odds are you can’t change.
Consider what you control and what you can change.
