As said above, the easiest solution would have been : get the last 300 people who joigned and fire them all. BUT, there is always a BUT :-) ; this is not the way the company is doing business; look around what is happening with other operators when they need to get rid of workforce; notice, payment, bye bye...
At least there is a wide consultation, working groups etc.. of course it is not pleasant to have to choose, of course one can argue that the hot potatoe is in crews's hands etc.. However, theses proposals are targeting everyone from the 62 years old to the early joiners; EVEN the one's whom are NOT yet in the company (ie ab-initios).
You can dump S... on a company as much as you like, but you should recognize when they do creative things. Get the numbers right, breathe, think, sit on your hands for a while, THEN act , speak...
µHave fun, and I wish you all a bizjets company that treat you like NJE does..
