TEACHERS? Teacher's Unions (as well as various other service workers...like the Department of Water and Power) are notorious. Their authoritarian and misappropriation has been the top story in California off-and-on for decades. This isn't to say that unions are a bad idea, but there's a direct correlation between union leadership corruption and 10th percentile income bases those unions derive from. They fail uniformly (over a long enough period of time) to prevent bad actors from subverting their purpose.
