this is not an alright jack attitude, which would you prefer? retern to temporary contractors OR 70% full time employees. And yes the job security of all at jet2 is a MAJOR consideration..
I think this is a reasonable response to a problem Jet2 had to face and a far better solution than offered by other airlines (Thomas Cook was one example i used).
As always these solutions are not ideal, but in case you didnt notice there is a recession and costs HAVE to be controlled, if you think it is unethical then you have a choice.
Once the cyclic curve changes then the pilots may be in a position to improve on their terms, until then other solutions have to be considered.
