Prob should start then. I've done this every time my responsibilities get to a point I can do another job for more pay. Or less responsibilities for more pay. Making your boss aware that you're valuable is the start.
It's not automatic very few people will actively just give you a pay raise. That's just how people work.
If I'm wrong I'm currently 20% better off than last month wrong. Doing nothing and bitching and moaning is entitled behaviour.
