If this happens, unionists have hinted direly of a general strike and action from their brothers on the docks in other parts of the world, but at a time of high unemployment you'd have to wonder how much support there would be for a nationwide downing of tools.
I've read statements from both the Ports and the union, and both sides' demands appear reasonable. Yes, the Ports need a more flexible and productive workforce, but the men also need some certainty in their hours of work and a base income so they can look after their families.
As someone who grew up in the 70s, when battles between unions and the Muldoon Government were hard-fought and furious, this dispute is reminiscent of that era.
And though I respect the Maritime Union's fierce protection of its members, I can't help wondering whether this sort of old-school, hard-line unionism has had its day.
Whatever happens, a year from now the Ports will still be running.
The Maritime Union officials will still be employed. The only losers from this look likely to be the working men themselves.
