The only people who will give a $hit are the resettlement folks. As for the hierarchy, they couldn't care less - you'll just be a statistic helping to solve Binnsworth's manning surplus.
You'll probably even have to pay for your own Dining-Out these days - and it's unlikely they'll want you to give a speech if you haven't been a party line worker bee.
It can work both ways though; I didn't go to the airlines, but I'm told that those who have often tip off the airline recruiters about which other mates to look out for - and which back-stabbing ex-senior officers to black list!
