They were up against a lot: Each yellow cab taxi driver in New York City has been classified by the city as an independent operator —a status that excludes them from coverage by most U.S. labor laws and that means their union cannot appeal to the National Labor Relations Board for recognition of its right to represent workers. But these supposedly unorganizable workers refused to let anybody tell them whether they could be a union or not. They organized a union themselves.
