i have every sympathy with people who are being made redundant. Its really isn't great.. i kinow having been there myself before.
The fact is though that the airline is a buisness and not a charity. If there is not work for these people what do you expect the airline to do with them?
Look at Ryanair, BA Aerlingus et'al they are all are cutting back... Jet2 is not on its own here.
I hope everything works out for anyone who looses their jobs. Good luck to all concerned.
