That has to be one of the dumbest things I've seen you post...and you've said some stupid %&^t...
FYI, the CP's from both sides already have been given direction from the company on this...and you won't like it, it is NOT what you are recommending. A CA claiming to be unable to perform under this issue is reeled in, if it's the FO thats the problem, they BOTH get reeled in, the FO for his marginal emotional state, and the CA for his inability to control the cockpit. And by reeled in, it will include time off...or worse...( by the way, this is straight from a CP) The company will replace a CA who is too fragile to control him/herself...because the company deems this relatively trivial, considering what type of emergency could ACTUALLY arise, and their fragile state will render them incapacitated.
