Honestly, if the code of honor is that restrictive that you're not allowed to be critical of your own ranks, there's something wrong with the code.
Are you sure you're an instructor for NAUI and not the Pyongyang Scuba Association?
Rather than attacking BoltSnap for his comment, perhaps it might be better to examine the codes of ethics / practice of various training / certification agencies, as well as other professional organizatrons.
For example, in the PADI Member Code of Practice the statement is made that a PADI Member will:
12. Not disparage the PADI organization, PADI Members or any other dive industry professionals.
Note that applies not only to criticizing other PADI professionals, but dive professionals of other agencies as well.
And, at the end, the Code also states,
'If you breach the Code of Practice, your PADI Membership is at risk.'
What BoltSnap said about NAUI is consistent with the standards of many agencies.
The goal is not to suppress truth. Rather, it is intended to point out that subjective professional bickering and fits of jealousy are NOT the proper attributes of any professional.
Bar associations, and medical associations, in the US and elsewhere, adopt similar standards of professionalism. Would you suggest that the ABA and AMA should be renamed as the Pyongyang Medical Association, or the Pyongyang Bar Association?
If I disagree with what another Instructor does / did, and wish to publically comment on it, I might say, 'I do not beleive I would not have done the same in that situation . . . ', probably giving reasons why I would not have done that, and leave it at that. That is a personal statement regarding my own behavior, not an indictment or disparagement of another dive professional.
If I disagree with the practices of my training agency, I can express my dissatisfaction by a) direct communication with the agency headquarters, or b) discontinuing my affiliation with that agency. I can even publically state what I disagree with, and articulate specific reasons why I disagree and what I would like to see changed .
Just a thought.
