Think about it this way. If his salary is significantly higher than yours but he can hand over the job to you and you can do it competently, you are in the running.
Thats the thing, its not. Mine is actually higher. If he gets the job then he will be doing far far too much work (and at a high technical level) for someone on his wage
If I get it then I would probably take a pay cut to his, which I would not be used to and get twice as much work too
What ****** me off was that the school still got me to apply for the job, even though they were going to give it to the other guy anyway because he had been working there longer.
