Can I sue my ex employer?

More than likely you cannot successfully sue your previous employer based on the facts contained in your question. You "guess" you walked off the job? Ordinary job related stress is not sufficient to constitute a constructive termination in most states. Most states' laws recognize the principle of employment at will.  This means your employer has no duty to keep you, and you have no duty to remain employed by the employer. A corollary right is what we sometimes call the "golden rule." ("He who has the gold makes the rules.")  The law might be different in Ohio, but I doubt it. You definitely should consult local counsel in Ohio to  find out whether these facts are sufficient to give rise to a successful claim against your previous employer. Michael Caldwell 404-979-3150
