When Monica Stonier first started working full time as a teacher in 2001, she was more focused on learning her students’ names than about her union, the Washington Education Association. But now Stonier, who has since been elected as a Democratic state representative for Vancouver, gives more thought to the future of organized labor.Stonier said that somehow the Freedom Foundation, an Olympia-based conservative think tank, found her home address. Like thousands of other public employees, she receives a letter each year reminding her that she can limit her financial support for her union.In recent years, the U.S. Supreme Court has ruled on a series of cases that right-to-work advocates hope will further the decline of organized labor (particularly among public-sector employees).The Freedom Foundation has actively sought to reduce the power of public-sector unions using these rulings. Last legislative session, Stonier, and other like-minded lawmakers, passed legislation intended to minimize the impact of court rulings unfriendly to unions. This legislation could soon be put to the test.In June, the court is expected to rule on Janus v. AFSCME. The case is centered on an Illinois state employee who is arguing that being forced to pay fees to a union for representation violates his civil rights. A ruling in favor of Janus would overturn a decades-old precedent and could significantly peel back support for politically influential public-sector unions.
