Macro, I am so very sorry…that sounds like a horrible headache to deal with. Like lbjames, I suspect this could go on a long long time. Good luck.
More likely though, he is probably making 40K a year, and is a recent hire. Or else, he is a contract worker, which means he is making $25K a year, is 50+ years old, and has had a sketchy employment history. Who else works for that kind of money? Or he is a contractor, and entry level. Or else, he is making 80K a year, is unqualified, and someone higher up knows him from friends/relatives and hired him.
