Good for you Engineers, well done and go for it.
There is a huge global shortage of qualified engineers (as bad if not worse than that for pilots). QF have treated you appallingly for too long.
There are too many naysaying whimps around like
seldomfixit and
ultralights who no doubt whine like stuck pigs when they don't get their own way but don't do anything collectively to fix it.
'Lambs to the slaughter' my arse, what have you guys got to lose? Worse case scenario everybody gets sacked - then what? Somebody still has to maintain the aircraft.
There are too few engineers and many, many jobs. Basic supply and demand. You should thus be rewarded accordingly and it's about time you were (and stood up for yourselves).
Just look what the Victorian school teachers have achieved by being tough and united. Unlike us pilots who are the biggest bunch of self-serving whiners unable to work cohesively and collectively even at this historic time of flight-cancelling aircrew shortages.
Good luck to you.
