How do I ask for a raise when I share duties w/ another & she makes more?

There is another girl in my office that shares my duties, and she make $3 more an hour than I do. I have to juggle more than she does (honestly). Should I let my supervisor know that I know how much the other girl makes? I'm not trying to match her pay an hour, I just want to get closer to her pay rate. Please help....

You can ask for whatever you want. To be successful, you should have a valid reason. Generally, the "She makes more than me" method is annoying. You should be able to show how you provide the company with results. You should also be willing to leave the company.

DO NOT whine and say She makes more than you. They have a reason for giving her more,even though you may not know the reason.
YOu need to give reasons why YOU deserve more, regardless of the other person. Express your recent achievements, your diligence , attention to detail, etc. Explain the EXTRA responsibilities that you have taken on and how you think that is worth $2-$4 and hour more.

Has she worked there longer than you? If so, you have to expect her to make more than yourself.

If the company is trying to hire more people, that may be a golden opportunity time to ask for a raise." Recruitment costs are high and everybody hates screening resumes and interviewing candidates," he says. "This would be a time the employer definitely does not want to lose a good employee and have to hire even more people."

The most natural time to ask for a raise is your regularly scheduled performance review. Other strategies to consider around the time of your annual performance review are to study salary surveys and market statistics for the pay in your specific profession, and be prepared to discuss your achievements and specific accomplishments over the past few years.

Find out what other companies are paying. Some mentioned how long you have worked their. Don't get into that, your value to the company only goes up with time if you accomplish more.
