Sure it is true that counting your narcs is extremely important, I don’t see that to be the issue. The issue is that you were terminated without substantiated cause. Aside from two pills missing ( in one incident) there is nothing else to show that you were dishonest. If it was an accident ( which can & does happen) A probationary period or recorded warning would have sufficed. The missing pills were your responsibility as you took over the cart and did the joint count, but it is not grounds for firing. Unless you have a history of mistakes ( which it sounds as if you don’t) or they have some other evidence to prove you an incompetent Nurse you DO have a case and SHOULD bring it. The only way To have equitable treatment in the face of any corporate entity is to demand it. Not only that, but winning said litigation sets important precedents that help to prevent similar things from happening again.
