Do not under estimate the strength of your hand at present. Any official talks around strike action will kill the flotation, and therefore your directors £tens of millions are on hold once again.
Then again, there are many longer serving pilots for whom the flotation will be a nice windfall; so already you're divided!
Presumably your reps have seen the business' forecasts that will make up the prospectus and let you know the current proposed pay increases for the next 5 years, which will have also been reviewed by external accountants.
Equally, whilst G-60 and co do a great job of underselling themselves, the flybe flight deck is generally made up of hard-working, clever and sensible guys and not just any fatpl holder - so the real supply isn't that great. In fact, to get what they do for £30k+ a year for people that have invested £50k is bloody great value, even in aviation.
