Your linking of the app with supposed KPI or 'performance interviews' (neither of which occur in the 'major Australian airline' with the app) is surreal.
Is it? I suggest with respect that you ought get out more, dislike the message but at least do some research before dismissing out of hand what is occurring outside the Australian exceptionalism to which some people still subscribe. Control of pilot work forces is an objective that runs deep in HR circles.
The CAR 234 gives you protection to do as you see fit, yet they will take it away from you without resistance just as they are hoping; You refuse to see what may be coming. Each individual can choose what they like, however you get no choice when it comes to CAR234. Strict liability is all yours.. The road to hell is paved with good intention
Fuel ladders exist at Cathay, as other poster have pointed out, ask the pilots at Ryanair. At least in Europe we have far more alternates.
'performance interviews'
may well be on the way. Probably to be introduced with a change to contract, sold to myopic people as some sort of upside.
Just like your clumsy uniform policy; an attempt to exert control
