"I quite frankly "lost it" and expressed in no uncertain terms that especially while the aircraft was in a "dynamic" state and with no other pilot in position, that it was absolutely crazy to not be totally monitoring the aircraft. His look said it all. I was an ornery old fart from a decrepit generation."
Sawbones,
It happens all too freqently and yes you are preceived as the bad guy. Had a older guy on my first leg ever with him who had just come from 747 SO to a 320 FO. Pushes seat back and pulls out a book at top of climb without so much as asking. Next leg he is PF and does it again only this time as we climb thru FL180. After our "discussion" he pouts for the rest of the trip.
Background experience seems irrelevant; military or civilian, it doesn't seem to matter.
