Re: Management - hear no evil, see no evil
I knew of a VP at a large company who made decisions and then remained ignorant of the serious arguably illegal consequences of those decisions.
If the topic was raised in a meeting, it would be shot down immediately. When that failed, the meeting was interrupted while they exited the room.
It was made clear to middle managers that forcing a VP out of a meeting would have consequences. This was communicated down as you would expect.
That said, at least one person at the coal-face thought this was a bit BS and explicitly CC'd this VP in email that laid out the problem in language that was unambigious and would cause more than embarrassment if found in discovery. This person did not get fired.
