The Price isn't right
If Handling Agents like Menzies hadn't started doing the job with too few men and hadn't cheapened the whole industry by cut-throat prices just to get their feet in the door, the industry would be able to charge the correct prices and offer living wages to their workers. I can't think of another job where you are responsible for £30m+ of equipment and hundreds of people on an hourly basis but only get paid 50% over minimum wage !
