In all Organisations there must be basic discipline. And whilst I fully appreciate that aviation is different, an aircraft is an Organisation and it needs a CEO. That being the Captain. It seems to me that having a member of the Cabin Crew serve as a spy on the Flight deck when one of the "Senior Executives" leave temporarily doesn't do much for the discipline or, perhaps more importantly, morale in this Organisation?
In every business I've dealt with, the CEO has a board of directors or some sort of executive committee looking over his/her shoulder. Get used to it.
In my line of work (engineering) everything I do is subject to peer/group review at a minimum. And there will be subsequent certification analysis and/or testing done to validate the adequacy of my work. People who think they are too good or too smart to be second guessed aren't suited for the job.
