The Auckland port has long been a battlefield, both industrial and ideological. The 1951 dispute remains an epochal event and even now it can be perilous in some company to refer to it as a strike rather than a lockout.
The industrially troubled 70s and 80s belonged to the watersiders. Casual labourers - known as "seagulls" - were gobsmacked to see how much the "wharfies" were paid, how little work they did and how readily they would call a stopwork meeting.
Corporatisation in 1988, and the formation of Ports of Auckland Limited, shifted the balance dramatically. Assisted by changes, in 1991 and 2000, to employment law, new-style managers presided over an increase in productivity, at some cost to employment security: more work was contracted out and the union muscle was seriously weakened.
That we live in a different era now is evidenced by the fact that the arm-wrestle taking place over the past six weeks at the port has not - yet - escalated into an industrial bloodbath. The port's unionised watersiders, represented by the Maritime Union, went on strike for the fifth time this week and the latest round of mediation talks on Thursday failed to break the impasse.
In a reverse of the usual arithmetic, the port company is offering a 10 per cent increase in the basic hourly pay rate; the workers want only 2.5 per cent. The sticking point is that the company wants to replace the existing eight-hour shifts with ones ranging from five to 12 hours; the workers don't like the uncertainty of such an arrangement and the potential damage to family life it implies. They want the existing contract rolled over for six months while both parties investigate ways to boost productivity. The deadlock looks intractable.
