I believe the pay agreement that at least one north sea operator has with the pilot workforce runs out in a couple of years time. Already some pilots believe that they are falling behind in the salary stakes (when compared to the fixed wing benchmark) and will be keen to see a big improvement in salaries.
A united workforce is (IMHO) the only way to achieve a sensible hike in pay. Difficult enough to achieve in the offshore industry, let alone in the general aviation sector.
