I've held my new job for four months now, and felt that I was being underpaid for what I was doing... so today, I walked into my boss's office, gave some statistics from salary.com and recruiters in the area for my job(or as close to it as I could get) and asked for a $10k raise. Five minutes later, it was done.
All by asking!
Today is a good day. I shall celebrate with a beer...or five.
