Don't agree with that at all! Beware. I suspect in the main, you will be marched out of the office pronto, having almost destroyed your career! There are established procedures. Captains may not report adversely on a copilot without first discussing it with him and placing it in writing. Are you even dreaming of suggestions a 'sneak' can creep into the office and start gossiping about Captains?
Beware accepting advice from anonymous posters that may place your career on the line!
