In East Anglia there does seem to be a shortage of full time instructors.
At the airfield I work at there are only 2 full time instructors(apart from the CFI), both of us still (just!) Restricted (pesky solo hours!), but lots of airline guy's doing it for fun once a fortnight. Personally I don't like this from a purely training point of view as it means students don't get the same instructor more than twice, unless it's one of us 2 full timers. Can't complain about the airline guys taking business away from us as we are rushed off our feet already.
I recently sent off a few letters to other clubs recently and got a fair few replies in the positive, I suppose knowing people there helps, but I feel that the shortage if not here already, is on its way.
If that means we get paid properly. Bring it on!! It would be nice to eat!
