For goodness sake there is no way ANYONE can be stood done for not extending.
The pilots simply cannot go beyond the LEGAL hours.
Cabin crew can vote and it has to be majority, and even then if you feel that you are fatigued you can walk off (as long as you don't mind a call from the visitors and months and months of harassment from QANTAS and intimidation)
Obviously some one did get stood down but not for NOT EXTENDING there has to be another reason.
