Scale this up a little bit, what if 4 or 5 locals deceide they want there own contracts will the rest of the company always be under the treat of a strike becuase each local is not happy, that is not solidarity, there should only be 1 master. The more masters there are it becomes watered down. The power comes from being united, The reason for suppliments was to address local concerns, not for each local to have a seperate contract. Local 705 wants better wages/benefits then the rest and they want the rest of the company to go on strike to help them get it. And they might get it, but what happens when other locals try the same thing and want to pull out of the master contract and negoitiate there own? It weakens majority becuase there no longer united as one.
