This should be the end of any discussion that unions are looking out for the workers!!

Of course, your post is about teachers' unions. This thread is about the UAW. Industry in the U.S. has only about 12.5% union representation as opposed to almost 50% in government workers. Over 500 posts and someone (other than me) finally posts a negative article about teachers' unions. What about firemen, policemen, municipal workers' unions, etc?
