Strike Over!?!?!?

Well, the TWU has decided that they'll go back to work and back to the negotiating table with the MTA. I'll be glad to be able to get around again but if the pension issue is supposed to be dealt with in the State Legislature, then it seems like the union is back to the 3/4/3 offer that the MTA initially gave them. So what was the point of the whole thing??? Any one care to answer that for me?
