Seventeen have admitted the interview and sim, so quite a few, and one other guy has already resigned for a biz jet job!
As to who goes, that's a personal choice to be decided by them. I know they are keen to get them to Doha ASAP, so depending on the outcome of the bull**** redundancy issue and the ongoing pay dispute many may well be off.
I think in recent months the management have overstepped the mark and people will be looking to move on.
As always though, it's a fluid world we live in.
