Said it before, say it again. Direct hire off the street bids for the hard to staff, bumfuck facilities no one wants to be at.
Sure you may have a some people who apply to BFE just to get in, but give the ATM some leeway to hire locally and I bet he or she can find some prospective controllers who will homestead where they are because they just want a good paying job with pension and bennies out there in BFE where they feel at home.
I bet you'd at least have more people not complaining about being there for longer durations if that's the case.
