You might start by explaining how it is that (in your opinion) public unions screw the taxpayers.
I already did up-thread. I'll try again.
1) taxpayer funds go to the police. The union skims off the top of their salary in the form of dues.
2) The union dues are then used to fund the campaign of a key friendly politician. Nudge, nudge, wink wink.
3) Contract renewal time comes up and the union reps sit down at the negotiating table across from the politician they helped elect.
Who represents the taxpayers? Not the politician, that is for sure. The union? Give me a break.
That's how you end up with taxpayers on the hook for making up the difference in ridiculously underfunded pensions.
These are the facts. It is not a logical debate. This is how it works.
