This great Wall St. Journal editorial (subscribers only for now) on how the National Education Association spends its money pointed me to this even better Department of Labor search engine that provides a window on just how labor unions spend the money union members must pay in via their dues.
There you can find little tidbits like the NEA paying Morris Costumes some $59,000 for “public relations,” no doubt costume rental for some NEA street theatre somewhere. Just a fun place to poke around.
