The reform plan was opposed by the Philadelphia Federation of Teachers. Protestors like J. Whyatt Mondesire of the NAACP vowed "... to shut down the streets", in protest. Members of the NAACP and a group of black ministers blocked an intersection in front of City Hall during rush-hour traffic. The day before, several hundred students walked out of classes. And earlier a crowd consisting mostly of unionized district employees marched on City Hall, where they disrupted the Christmas tree-lighting ceremony and drowned out the choir with their chants.
