The Caa need to first look at the practice of Level 2 ops sending a heavy crew out in the back, in normal pax seats, surrounded by pax and then having to operate home. Usually late night / early departures. Knacked when you get in the seat yet within FTL's.
Much less tiring actualy working both ways with use of discretion, but can not be rostered.
Same goes for staff carparks being in the next county.
And this is from someone who lives close enough to the airport to see the gear retracting.
