When I worked for a GHA about 12 years ago I think I was on about £3 an hour. There are a combination of factors that "conspire" to muck up a turnaround but I don't need to tell you lot that do I.
My company used cheap equipment, crappy uniforms, delapidated vehicles, poorly maintained radios.....
Add to this a really pisspoor airport owner with overcrowded and understaffed and inadequate numbers of security posts (there was no separate staff post so we had to excuse ourselves to the front of passenger queues) and what you get is..well crappyness multiplied.
Also while I was there the station head called us all into a meeting and declared we were all going to be doing the pushbacks as well - previously done by dedicated airline crews.
His parting words were "If you don't want to do it, you don't have to" - ie, we can always get another monkey to replace you, and curiously no mention of quid-pro-quo pay adjustment for our new extra "voluntary" duties.
T'was ever thus and I am well out of it now.
