Don't hold back, Old Schoolie, tell her what you really think!

Seriously, there's a modicum of truth in what Rainboe and Old School Flyer are saying here, and, as unpalatable as it undoubtedly is to many who are reading and contributing to this thread, when it comes to operating an airliner, "it ain't a democracy" is the final rule of survival that every crewmember needs to understand.
Unless you believe "Capt Queeg's" actions are going to quite literally kill you, if you're not wearing the four bars yourself and (more importantly) have not been given the tech log to sign for that particular sector by your employer, you swallow your pride, take careful notes on all the unreasonable behaviour he's exhibiting to be acted upon later - and then, most importantly, get on with your job and submit a formal complaint after you and your crew have reached the destination.
In my experience, it's amazing, on most occasions, how, when you sit down after the flight and catalogue all that unreasonable behaviour, on paper and in the clear light of day, (which is where your bosses are going to be when they see it), it looks like the petty storm in a teacup the high emotions you feel at the time really are. ("He didn't pick up the document until 37 minutes after you you slipped it under the cockpit door? Really? 37 minutes... Tell me more.")
