The teacher unions are the most cantankerous in the country. The seamen, the watersiders and the miners are pussycats.
Gone are the days of the ferries going on strike at the start of the school holidays. The freezing workers no longer hold farmers to ransom. The picket that left Mangere Bridge unfinished for two-and-a-half years is now unthinkable.
But the teacher unions? They're the baddest and the maddest. They dictate education policy, destabilise duly elected ministers of education and present themselves as the arbiters of right and proper schooling.
They're rich, powerful and unassailable. The New Zealand Educational Institute has 50,000 members and $18 million a year. The Post Primary Teachers' Association has 17,000 members and $9 million a year. That's a lot of money. And the teacher unions use it. They think nothing of taking out full-page newspaper ads and hiring commercial billboards to attack the Government.
The unions have a larger membership than all political parties combined. More critically, their members have close contact with mums and dads anxious about little Mary's education.
