No, not at all. I would tell the captain that his urinating in the cockpit is unacceptable and that if he did it again I'd get off the trip on the next stop and immediately report him to professional standards. End of discussion.
This type of behavior is unacceptable, unprofessional, unhealthy and indefensible. No one should be subjected to that type of work environment.
Part of being a professional pilot is not allowing yourself to be bullied by either management or another crewmember.
Agree 100%. Good post.
