Company slowly moving the goalpost:
"You'll get paid once the door closes and thereafter until it reopens, that's industry standard"

"Did I say door closes? Ahem.. Well I meant when pushback begins"
Another year passes
"it's always been when the aircraft moves under it's own power c'mon guys that's the policy we were just tracking the other two metrics"

This is to ensure the most efficient use of the runway surface of course"
