My problem is that glassdoor has information for my specific position, in my city, in my company but it's double what I currently make. I don't think I'm that underpaid but the taboo of employees not discussing salary leaves me without any real idea of where I really should be. I know for a fact I make more money in one quarter for the company than I earn in an entire year. I still asked for at least 20% more and am awaiting a response. Also applying for other positions.

The only big increases I've ever gotten were by switching companies or bringing a competing offer to my boss. People say the latter is career suicide but they are wrong.
