Too bad the unions don't. The WEA derisively refers to teachers like Mr. Carlson who want their money back not as free-speech advocates but "dissidents." The goal is to squash these dissidents by overturning Initiative 134, a law--approved by 72% of Washington voters in 1992--that requires unions to obtain written approval from teachers before dues are spent on campaigns or candidates. Back in March, the unions got a surprising assist from the state Supreme Court, which ruled that the paycheck protection law places "too heavy" a burden on the free-speech rights of the union.
The Washington law states unambiguously that a union may not use dues "for political purposes without the affirmative consent of the nonmembers from whom the excess fees were taken." The Washington Supreme Court somehow twisted these words to mean that the unions can spend as they wish unless workers object and affirmatively opt out. That's a big distinction, because the unions make it as time-consuming and cumbersome as possible to get the money back once they snatch it.
The case is discussed here and will go before the U.S. Supreme Court in January. Let's hope the court will help the teachers understand their liberal causes should not be supported by coerced money.
