I learned the hard way 8driver, told that CoS 08 was a one time offer, never to be repeated. Tripple checked this fact with 3 different senior managers. I reluctantly signed as i need to work a couple of extra years and i am close to the 55 mark.
Now I am out of 10 months bypass pay, business class F.O.C's etc. The "once only" offer ?, you can walk up there tomorrow and sign CoS08.
