Since we're talking about intimidation, let's talk about courtesy: a related concept. I just did a flight where the crew makeup suggested the rest would be organized based on everyones timezones. No email before the flight so what would you expect? Low and behold the captain decides on doing the opposite as he is is not sleepy yet. This screws everyone else around and we lob into Hong Kong with 3 guys with their eyes hanging out of their heads and one functioning crew member. Yes it is the prerogative of the commander to take whatever rest he pleases, but please a simple email would have made a huge difference to crew effectiveness, safety and job satisfaction. Even a late email would have allowed a quick catnap before the flight.
