As you know JQ fly the A320 with containerised baggage.
QF fly the 737 with hold stowed baggage loaded by conveyer belt.
As you know the 737 conducts close to 400 sectors a day.
To load and unload an A320 the individual item of baggage is handled only twice by JQ staff. Once placing it in the can and a second time removing it.
Compare that to the handling of the 737. The item is handled 6 times by a baggage handler. Once from the belt to the trolley, a second time from trolley to the inclined conveyer belt and a third time from the belt to the aircraft hold. The process repeated again from aircraft hold to the belt. Again from belt to the trolley and one more time trolley to baggage belt.
When you obtain some lost time due injuries data, say for example Baggage Handlers. Which in affect, your calling Qantas Mainline "Sickies". We can then discuss the work practices which exposes mainline employees to injuries at a rate 3 times higher than JQ.
