I agree Harry about the amount of work done in the office. Due to a medical issue, I had the joy of working in the office for a month. I was shocked at how little work was actually done!
It made me realise that the crew ( both flight deck and cabin) and the engineers are the only ones that actually work in the place. In fact if we produced the equivalent amount of 'work' that is produced in the office, we would do one flight a week!
On another matter, I can't see how the current rosters are sustainable. 96 hours, long haul, back of the clock. Something is going to snap. It's simply not safe, and I fear what it is doing to people's long term health.
