The largest teachers union in Michigan still represents Jason LaPorte at the bargaining table, but he no longer pays anything to support the union.
LaPorte and thousands of other public school teachers stopped contributing to the union after the state's new right-to-work law took effect in 2013. Membership in the Michigan Education Association has since dropped by 19 percent.
A similar fate could soon be in store for public-employee unions around the country as the Supreme Court considers whether government workers who choose not to join a union can be required to nevertheless pay fees that cover collective bargaining.
The high court hears arguments Monday in a California case brought by a group of public school teachers who claim such mandatory fees violate the First Amendment rights of workers who disagree with the union's positions.
