Ok then how do you handle the FO who keeps on wanting/trying to "run the show"?
Some years ago I had a conversation with a Flight Ops Management type on this subject. He related a situation that he and other captains at his base had with such an F/O. Said F/O even got to the cabin crew first, and chose all the meals he wanted.
The resolution as related to me, was that all the base captains had a chat and agreed that no matter what Bloggs wanted, they would all countermand it. If Bloggs wanted to climb to a higher level, they'd descend or hold level. If Bloogs said he'd eat second, they'd make him eat first. If Bloggs said he'd have the salmon, they'd take it.
Apparently it only took 2 weeks to prevent the "running the show".
