Law advice for compensation after a promotion?

(2005) After 1 year of submitting to personnel that I had been doing the duties of Administrative Associate since 2003 instead of my hired position as Administrative Assistant, the personnel dept admitted in writing that I was in fact doing the duties of the Administrative Associate so I was promoted (2006). The promotion included a $1200 a year raise that would put me just slightly over the minimum salary of an Administrative Associate.

But I had received 4 years of state cost of living raises and merit increase raised (offered to all employees with a "Very Good" on their annual evaluation). The personnel dept did not decipher the money that included these employee wide raises and just added onto my yearly salary to put me into the minimum salary bracket.

What is this called, and how can I sue for retro pay (back to 2002 when hired until today still employed), and have my base salary changed to reflect ?

Thanks

"Performing at an excellent "above and beyond" level got you a promotion." - actually, when they saw what job duties I was performing daily, they admitted that I was an Admin Associate...the promotion was just an admittance that I was doing the job already. It even states that in my letter ....

Based on what you've written, I'm not sure you actually have any cause of action. They raised your salary to put you within the salary structure for the job you are doing, but they aren't required to give raises and bonuses etc. unless it's specifically set out in their employment documents. If you are a government employee or part of a union, you may have some kind of guidelines they must follow and which they may or may not have violated.

If you are an "at will" employee, they don't have to do anything more than they've already done. If that's the case, I would suggest you talk to them about what you feel you should be receiving versus what you're getting and ask for a raise beyond the $1200 they've given you. Suing them doesn't sound like the way to go.

Unless there are some very strange laws where you live, you can't get anything.

On the limited facts you state, you have no case.

Performing your own job well got you the merit increase for that job, not for a different job.

Performing at an excellent "above and beyond" level got you a promotion.

Continuing to complain about it could get you fired.

Congratulations on your promotion.
