American Federation of State, County, and Municipal Employees, Council 31, 585 U.S. 878 (2018), abbreviated Janus v. AFSCME, is a landmark decision of the US Supreme Court on US labor law, concerning the power of labor unions to collect fees from non-union members. Under the Taft–Hartley Act of 1947, which applies to most of the private sector, union security agreements can be allowed by state law. The Supreme Court ruled that such union fees in the public sector violate the First Amendment right to free speech, overruling the 1977 decision in Abood v. Detroit Board of Education that had previously allowed such fees. Wiki link
