Also, if you're going to cite the numbers of the longshoremen's incomes, which are coming from the employers, it's useful to provide the details - that those who are full time make that much on average, but most do not have full-time employment, removing them from the denominator of the average. The longshoremen retort that they make $26-$36 per hour, but how many of those hours that they're not being paid are they functionally 'on call'?
I honestly don't know the answer to any of it, and the numbers that are out there are being massaged by both sides to make their point. It'd be interesting to know the comparative data on injuries and fatalities among longshoremen in comparison to other industries. Do they have a point about the safety standards, or are they using it as leverage for more pay?
