When I was an engineer I found out that I actually got paid more than some of my coworkers. I think that -at the time- the HR guy rolled out the red carpet because I offered him about 9+ leads of people looking for work there.
Since everyone there pretty much got laid off -I've come to the conclusion that it
just doesn't matter and that you should always hold out for more pay.
Of course right now I aint makin anything...
