I would have to assume Joe is aware of this by this point. Sadly I just do not think he cares because he hired her (after 18 months of people turning down the job) so this would be a bad reflection on him. And we all know how a narcissist, like himself, would view that. And to note, her minion Brad is just as bad. How this pathetic clown even woks at the same organization as a lot of us is embarrassing in itself.
At this point nothing is going to change so either stay and collect a paycheck or follow suit like the majority and leave for a better QOL.
