Im not sure id agree with that.
Previously when QF did their ground services in house, bags would be delivered promptly and nearly always with priority bags first.
Now its been outsourced, bags take forever and with little to no priority sorting, not due to tall poppy syndrome but simply because the labour resources has been cut back to the absolute minimal so there is no time for any sorting and the ground stuff are constantly under staffed and rushing from one job to the next. The issue lies at the top - not at the bottom.
