Here we go again.......market forces.......many, many "professions" are affected by this. And since the demise of union protection for most, there's only one way for fees to go in a market which has an oversupply of skilled people. The wages for heli instructors and other freelances will remain in vortex ring until someone either creates a shortage - or says no to the money.
'Tis the way it's always been in the "free" world.
Get a union together - a rotary-only union. Get recognition. Get represented. (Oh God - I feel a Michael Foot duffle coat memory coming on.)
