The unions argued that so-called fair share fees pay for collective bargaining and other work the union does on behalf of all employees, not just its members. More than half the states already have right-to-work laws banning mandatory fees, but most members of public-employee unions are concentrated in states that don’t, including California, New York, and Illinois.
Labor leaders fear that not only will workers who don’t belong to a union stop paying fees, but that some union members might decide to stop paying dues if they could in essence get the union’s representation for free.
A recent study by Frank Manzo of the Illinois Public Policy Institute and Robert Bruno of the University of Illinois at Urbana-Champaign estimated that public-sector unions could lose more than 700,000 members over time as a result of the ruling and that unions also could suffer a loss of political influence that could depress wages as well.
