She was charged with a felony (B) and now she is doing probation. One of the conditions was to tell her employer about the sentencing. It is a bank. Since she was a good employee the bank gave put her on a personal leave and a chance to just resign since the said she can’t be bonded.
After the probation the felony will be G misdemeanor. Will she able to be bonded with GM?

I would suggest she seek another career. Banks don't pay that well anyway.

First what country are you in, and if the US what state.

Normally a felony after probation is not reduced to a misdemeanor, so I would check on that, But depending on what the actual crime was, theft, drugs, jaywalking, will depend a lot more. And of course having this on her record at the bank that she had to quit for this.

But I would agree, depending on the crime, they may consider changing careers
