B,
I hear what you say but the reality is that there are folk here in Wilts who have spent their whole time here and no doubt ISK and other places will have similar.
If you are a Nimrod AEOp and didn't want to go any where else, once St Mawgan closed where the hell were you going to work?
If you were a Herc ALM and had no desire to move why would the poster move you?
The baldrick world has not functioned in that "3 years and move" manner for years.
I really hope your rosy outlook is right but the cynic in me thinks there will be quite a few folk who are not taking this quite as calmly as you depict.
