Absolute truth! Also, there is HAVING a legal right and there is ENFORCING a legal right. These are most definitely NOT the same thing. Believe me, you do not want the time, expense and uncertainty of litigation in these situations. Please be very, very, very careful discussing anything related to labor rights or actions at work or online.
You sound like you are perhaps in the denial stage of grieving for your former job. Do NOT hang on, hoping you alone can change an institution. You can't. You can, however, ruin your physical and mental health. Take your wonderfulness to somewhere that appreciates you! (Hopefully, somewhere close to me where students could desperately use a nurse who wants to precept students.)
