Rabbi Aaron Rubashkin, owner of AgriProcessors (Aaron's Best™, Rubashkin's™, Shor HaBor™, etc.), and his son Rabbi Moshe Rubashkin collected union dues from employees and pocketed the money themselves, rather than turning the funds over to the union as required by law. They got caught. The Forward reported this Friday. (Our report on this was posted 14.5 months ago, on March 13, 2005.)
Here in PDF is the decision finding against the Rubashkins from the National Labor Relations Board, in case you missed it the first time around.
