Mobi LAME,
I think you'll find that the very large PER QF engineering Mgr will attempt to/not pay for any endorsement/approval possible to make his bottom line and himself look good to his boss (aka M) in Syd.
All the while to the detriment of his subordinates who have to run around like chooks while on shift due to a lack of coverage or bulk O/T for the haves versus the have nots.
It's unsustainable big fella.
