I probably already make more money than he does. This company likes to bring people into management fairly early into their careers. So it is a faster path to more money. It takes longer to get there but a Sr Engineer makes more, and has the potential for overtime.ask him what he gets paid now so you can take over his job at a much higher pay
He would have to sell his soul to the corporate devils to get promoted here, he is a pretty good dude and I think he wants to take a more palatable career path.
