Apparently she had done this reporting idiocy, then she was stongly suspected of having been involved in a bomb phone threat in UK (but without proof obviously) then probably add some attitude problems - so reporting the Captain was the last nail in the coffin - BYE BYE !!
I know an Irish airline where the purser reported the Captain "for turbulences unavoided during the flight" to get revenge as she had been arguing with him beginning of the flight for a passenger matter, and she wanted to be the one "in charge of everything behind" .... BYE BYE also !
Good it happens from time to time.
