Fair enough Fly 747, but bear in mind that they are not being employed as DEFO. They are starting as SOs with zero time. How are they going to be highly employable having only S/O time in their log book. They most likely won't be employable until the 2nd year as F/O, in which case that would mean 7 years at Cathay before they can be employed elsewhere. Then they would have to start at the bottom again. Leaving for another airline will only work in their favour assuming that most of the equivalent paying airlines in 7 years time are still expanding like mad and time to command is relatively quick.
