And the purpose is?????

The Boston Police were going to picket the Democratic convention due to a pay dispute with the city.  They were forced by a judge to go to binding arbitration.  They won.  Now the union says they still plan to picket parts of the convention

"behalf of other municipal unions that lack contracts and to show their displeasure with the way their binding agreement came about."

Can someone explain this to me? They won and now they want to rub the Mayor's nose in the defeat? This will hurt all unions in the future. Management will look at the Boston Police example and say, why give anything since they will only demand more. So much for labor peace. From a political strategy point of view, the union has endorsed Kerry and yet they are not doing him any favors. If (as I hope) Bush wins re-election, the union loses because they will have no clout in the Administration. If Kerry wins, the union loses because they were more a hindrance then a help. Either way the union loses.
