When I was F/O there were few Captain like to scream and shout. I just follow SOP and they cant do much. Now I'm a Captain, I still just follow SOP and we cant be wrong doing that. If your Captain is giving you hell, just step down out of base, tell him that he make you sick and unsafe. If needed, go to doctor and get medical chit saying you are unfit. That will teach that guy. What I observe is, it is a give and take for most crew. My F/O is my last line of defense against any mistake that I might make. We are human and we do make mistake. That is why we need 2 man crew.
