Heard rumblings on the flightdeck about a few people. Some names even mentionned although I did not know them personally. Never heard a number, just 'a few'. Some are fairly new but one I know of has been with CX for quite a few years (10+).
A few demotions including capt>F/O, and F/Os losing their relief qualification.
However having heard some stories of the relief guys in particular, it does not surprise me. Perhaps management have realised they can't just hand out RQ to people willy nilly.
