I think there is not time to waste, we need to go back to 8 hour shifts.
Our people can not work 12 hours with no breaks. We are suffering from extended hour shifts with no or little breaks.
We are hounded by management to sign for unserviceable aircraft and being so fatigued, someone may just do that
(soooo fatigued, stressed & demoralised)..
The BIG BANG theory may be about to re-materialise.
Time to take 5. ie go back to 8 hour shifts.
