Perhaps I'm just fortunate, but in my current situation, I don't think this would matter much. Sure, my co-worker may get a larger raise, but I'm pretty comfortable with my current salary, and the fact that I can average 40-45 hours a week with a lot of flexibility in when I work those hours. Perhaps one day, my boss will turn evil, and tell me I'm not producing enough, but, at that point, I'll find other work, because I have no interest in working for company that expects 60 hour weeks to be the "norm."
