The laws for wrongful termination or discharge vary widely from state to state. In an "at-will employment" state, which includes most states, employers may hire or fire for any cause or for no cause at all. If the reason for termination or discharge, however, is a pretext for some underlying illegal reason, then it may be considered wrongful termination. Illegal reason to terminate an employee under United States law and the Federal Civil Rights Act can include retaliation for filing a claim of discrimination, sexual harassment, or hostile work environment. Likewise, retaliation after a whistleblower action can be considered wrongful termination. Contact an attorney for legal advice about a wrongful termination case in United States.
