Maybe said ops mgr's now know they're in the firing line and are willing to dissent.
But Qantas is not a democracy, the line managers either tow the line or they get the boot. Have you noticed that:
-They send out pre-scripted 'managers information packs' telling them what to say
-They send out HR staff to monitor/police what they say, no doubt just in case they interject with some truth
Now that they have Maintenix, they also now how the ability to run quick analytics on the workforce. Everyone needs to make damn sure they treat their day to day as an astute business would, as in logging every fault into maintenix.
