Janus v. the American Federation of State, County, and Municipal Employees. It鈥檚 the case that had the education community fixated on the Supreme Court for months, wondering how a ruling for the plaintiff could impact the nation鈥檚 teachers unions.
It arrived on the last day of the court’s 2017 session with a 5-4 decision finding for Mark Janus, an Illinois state worker who argued that it violates the First Amendment to require public-sector employees to pay union dues 鈥 even to help fund collective bargaining and other shared benefits 鈥 when they disagree with their union’s positions.
In another potential game-changer, the majority also ruled that members now have to affirmatively opt into the union, unlike past practice where dissenting members were required to opt out.
We鈥檝e been tracking the case for the better part of a year now and have published more than a dozen primers on the key issues involved 鈥 and the potential implications for public employees.
