"Less cost will be cut by sacking 78 from the bottom than by getting rid of the 20 skippers who want to go at the top"
I bet you hav'nt got the first idea what the "enhanced terms" for the top twenty would cost (my guess would be several million). If it was cheaper - they'd do it, no one hates unions more than they love money!
(And being so angry is bad for your health - take a deep breath followed by a cool Guinness...)
