Well, for one thing we have a lot of “lifer” types, including people who got stuck in the lost decade and now have too much time to be marketable, plus a fairly good sized portion of our junior captains who live in base aren't in a huge hurry to leave. Many will wait a couple years after upgrading to start applying other places.

Those who want out quickly and put the effort into it (and don’t just ***** about not getting a call incessantly without making active steps to change/improve their resume) typically get out quickly.
