Working long hours doesn't immediately excuse you from adhering to social contexts, especially when there are obvious power structures present which evidently is rampantly abusive across industries.
'Innappropriate incidents' is entirely subjective and can't be defined beyond a personal context. If one party believes the manner in which someone else operates in a context is inappropriate, that's enough of a definition, especially in the context of such a survey.
That's unacceptable. If there are no firm, objective rules then anyone can be guilty of anything and "inappropriateness" loses all meaning.
I could consider the fact that you don't pray before eating something inappropriate in a work dinner context.
The "inappropriate incidents" bit is not "completely undefined" - it refers to the things in the list that follows. I think for a survey the response was surely detailed enough?
Also 'inappropriate incidents' is completely undefined.
