How much should a department assistant be getting paid at a law firm?

Well here's the skinny; I have a friend that's a department assistant at a law firm. She only works part-time, cause she's also a full-time teacher. But she's been working at the firm for about 9 years while teaching. Recently, she's been wondering how much someone in her position at the law firm should be getting paid after working there for 9 years, and if it would be a good idea to ask for a raise. Can anyone help?

Tell her to go to payscale.com website. It will ask you a bunch of questions (skills, position, location, etc...) it will give you the end result of how much she should be earning.
