I'm confused. Are they hiring or firing? now that the hiring is all on, are they still 'asking' crew to take several years unpaid leave???
They were overstocked on Capt's and F/O's on the B767 fleet which is slowly being phased out, but very short of second officers.
Instead of down-training people they offered LWOP to those they were overstocked with and are now hiring for the short second officer rank.
Possibly all evened out when the 787 arrives and the LWOP chaps return from the sandpit and the orient.
