Just do what you think is right.
My gripe is with the management not you, whoever you are. However I do refute that I am as responsible as the Jet2 management for the erosion of the whole industry's terms and conditions. As Jet2 have only been in the passenger business for a couple of years I don't think they can be held directly responsible either. Instead look more to the original players in this area, Ryanair and Easyjet.
Seems like a good deal at Easy now, but how long has it taken? Easy pushed to the brink over such a long time and they were allowed to. That payrise doesn't look quite so rosy once it is recognised the timescale since the last decent rise. Very similar scenario to Netjets in US.
