Q: After 3yrs. on the job it's evaluation time. I've always gotten excellent evaluations but have always been told nobody's

A: There are no legal issues here. Employers set their own pay scales (unless this is a public employer), raises, and reviews. In fact, they do not even have to give reviews, have pay scales, or give raises.

A: These facts, on their own, do not present a legal issue. You have not indicated whether you work for a public employer, or whether any contract, such as a collective bargaining agreement, governs your relationship with the employer. If you are a tenured public employee or are part of a bargaining unit, there will be legal and contractual provisions that apply. If you are an at-will employee, your employer does not have the obligation to give you raises or performance evaluation.

I noticed that you stated: "GA is a right to work state." I am answering your question based on the notion that your employment is "at-will." Right-to-work refers to situations (which differ a bit among states that have right-to-work laws) where labor unions and unionized employers are not permitted to require union membership or to mandate certain payments, such as fair-share, from workers who choose not to belong to the union. I understand from the context of your question that you mean you are at-will, not that you are paying fair share. The at-will employer-employee relationship means, in theory, that either you or your employer can terminate the relationship at anytime for any reason. In practice, there are many reasons an employer may not terminate or otherwise negatively affect the relationship (i.e., discipline, refuse to promote, etc...). For example, depending on the size of the employer, various federal and state laws relating to non-discrimination will apply. Almost all employers are subject to at least some laws forbidding illegal discrimination based on protected classes. You have not suggested that you have faced such circumstances.
