600 ft-lb:
The engineers were obviously considered not good otherwise they wouldn't of been treated like they were scum.
No! No! No! 600ft-lb, you don't understand the mindset of these managers! The actual ability of the engineers is irrelevant to know nothing managers! What the managers want is abject subservience - compliance, even when the engineer knows that the manager is wrong.
This is the crux of the entire Qantas problem! All staff are regarded as replaceable automatons in that no one is better than any other one, and the automatons don't have to be too bright either, just compliant and follow orders!
