On Obtaining Appropriate Compensation...

wpc4 asks: "I've been working at my current place of employment in California for going on 2.5 years. I work for a rather big HMO providing IT support for over 2000 users. In my time there I have had no negative feedback, I am the "go to" for the department, I have improved our service area's image to other IT departments in our organization, had one promotion, and so forth. I am currently making over $5k less than the minimum for my title, while some new employees just got hired with the same title and lesser skills as myself and were hired on at over 30% more than I make, yet I have 2.5 years of seniority. Since I'm not union I don't appear to have any way of trying to get myself compensated appropriately, is there anything in the California labor laws that I can pull into play? Any suggestions at all before I look for other employment?"
