Is there anything I can do about unjust firing ?

So employment in most states is at Will meaning you can be terminated for any reason or no reason as well as your privilege to separate for any reason or no reason from your employer. However, when it becomes illegal is when you are terminated based upon a civil rights violation. This would be for example like racial discrimination, gender discrimination, disability discrimination, color of skin discrimination, ethnic discrimination, religious discrimination, etc. If you feel that the motivating factor in your termination was due to a violation of your civil rights, then you should discuss your case with an employment lawyer for specific advice.
