Can an employer fire an employee if he or she discussed a how much he or she makes

Your question provides too little information to give you a definitive answer. Generally, employees in Georgia work "at will." This means that their employer does not need a reason to terminate the employees, and the employee doesn't need a reason to quit. So long as the employer's reason for terminating the employee is not unlawful, the termination itself is lawful.   Terminating an employee for discussing his/her wages may or may not be unlawful, depending on the context and circumstances of the discussion. If you have no contract of employment the question is decided under federal law. It will depend on whom you told your wages to, and for what purpose. If you disclosed your wages to a fellow employee, or to a union organizer in a discussion of whether you were being paid fairly or adequately, your actions could be protected as "protected concerted action" under the National Labor Relations Act.  This assumes that your employer is covered by the NLRA.  If the employer is not an airline or railroad or a directly related company to those industries, and if your employer purchases and sells at least $50,000.00 from outside the state of Georgia, (I think that's the dollar volume minimum level, but I am not positive) it would be covered by the NLRA. An employer could not lawfully fire you for engaging in protected concerted activity, Doing so would violate Section 8(a)(1) of the NLRA. You would need to file a charge with the NLRB within 180 days of the illegal act claiming that your employer discriminated against you, restrained and coerced you in your exercise of your right to engage in protected concerted activity by firing you for discussing your wages with fellow employees (or with a union organizer).
