Many thanks for laying that out.... I have a family member who is having this discussion with her boss right now and your suggested letter is quite timely.
I would suggest anyone involved in this matter with their employers might do well to eliminate any references to the Nuremberg Code entirely without doing some serious research on it yourself. My understanding is that the Code has never been formally adopted into law or accepted as an ethical standard by any medical association. If this is true, then you make yourself look like a damned fool who got conned by internet trolls — which might make you a candidate for termination in any case.
