How would you recall him?

He/she won't be elected by the pilot group directly, so I don't see a recall being a player.

If he/she is appointed by the MEC, then you've got all sorts of political layers and alliances that could either protect him/her, or shoot a bullet through his head, and if so, no one will ever want to do that again.

it's a lose-lose. Don't see you being able to recall him/her. so no real direct and immediate accountability.

The ALPA ship is built for stability, like a huge aircraft carrier. Takes six months to turn on a dime, so what you propose is at odds with how ALPA really works.
