I want to know about the fair pay act?

[this_girl_loves_the_80s]

I've read a bit about it, but most of what I've read is in regard to men & women getting equal pay for doing the same job with the same requirements and such.

I would like info about women getting the same rate of pay as other women doing the same job w/ same qualifications & such.

And also how can I use these laws so that I can get the salary that I an owed, because my job is screwing me right now.

I work as a CAD (computer aided design) Artist for a fashion company. Three of my co-workers (1 past 2 present) are currently making more than me for doing the same job. (coincidently we all went to the same school & have the same degree) I've talked to my boss about raising my salary (without bringing up my knowledge of others salaries) based on my work ethics & contributions to the company and he listens to what I'm saying, but promises nothing, and as a result nothing happens.

Anyways, any info anyone can give will be appreciated.
And please no suggesting of getting a new job.

With the economy the way it is, I'm don't really wanna do that.

Also I do like my job & the people I work with, my company also has good health benefits & vacation.
