Assault in the Flight Deck!

Jet Airways check airman is flying the rights seat. He slaps the captain. The captain leaves the flight deck, and goes to the back in tears. Forget the tears, removing herself from the flight deck was probably an excellent decision.  

I suspect if that captain had been a man, and the check airman hit him, that could have escalated into something catastrophic. The image of a brawl comes to mind. Needless to say, the captain removed herself from the situation to allow emotions to calm down before returning. 

But she was never given the chance. The check airman left the flight deck unattended to go find her! The question that is boggling my mind is, why was the Captain fired too? What did she do wrong?
