IF you believe (and believe the facts will support) that you were demoted because of your race--i.e. if you were not African American as are those two other technicians you mention, that you were discriminated against because you are not African American--then you may have a case for illegal workplace discrimination: the law says that you cannot make employment decisions or take employment action based on a person's race. If you think this is the case, one way to explore your claim is to contact either the federal Equal Employment Opportunity Commission (EEOC) or your state's equal/civil rights agency and file a complaint.Bear in mind that unless you had a contract (including a union contract) which is being violated (and if you did, then you may have a breach of contract claim or lawsuit), illegal discrimination such as racial discrimination is essentially the only "wrongful" demotion or other employment action. Employers are allowed to make unfair decisions or stupid decisions, or to favor one person over another as long as the favoritism is not based on race, sex, religion, age over 40, disability, etc.--but favoring one person because he/she is a friend or more likeable is definitely legal. So if your demotion was due to any reason other than illegal discrimination, it is probably not wrongful, even if it is unfair.
