Corporate-funded attack dog Rick Berman [3], who has previously attacked Mothers Against Drunk Driving [4], tobacco control advocates and critics of fast food, is on the warpath against teachers' unions. In a speech at the Conservative Leadership Conference [5] in Sparks, Nevada, Berman said "everybody should be afraid" of unions and warned that the Employee Free Choice Act [6], currently being considered in Congress, could lead to explosive growth in union membership and "change politics in this country forever." Teachers' unions in particular need to be attacked, he said, because people normally tend to like and trust teachers. "We have to reposition these people in the minds of the public," Berman said. "If you don't, you will always be fighting Mother Teresa. ... We have to marginalize their unwarranted credibility." A Berman front group [7], the Center for Union Facts [8], has been running TV ads featuring actors posing as unhappy union workers, and print ads comparing union leaders to Fidel Castro and North Korean dictator Kim Jong-il.
