Life simple in your world then Calm? Unfortunately I don't have a spare £21,000 to pay for an obsolete type rating, or any type rating for that matter, nor can I afford the "pay cut" to go and work on a 70% contract
If only my life were simple! Fortunately for those with enough thrust to overcome their inertia can and do move on to better things, because the opportunities are available if you're prepared to move. It's not a cliché! I would imagine there are E-Jet opportunities available if you bidded for different bases. Jet2 70% is not your only option, in fact not even your only option at J2!
Your assertion that there is no progression to be had is simply false. You just have to be a little more adaptable in these chastened times.
