NEW YORK, NY - DECEMBER 15: Members of the Transportation Union Local 100 and supporters from "Occupy Wall Street" participate in a protest before marching to Zuccotti Park to demand changes to the contract between the Metropolitan Transportation Authority (MTA) and transit workers on December 15, 2011 in New York City. The MTA is seeking dozens of work-rule changes that it says will increase productivity and reduce labor costs that the union is against as it will increase their workload without a pay increase.
