An Illinois home care worker argued that being forced to pay union fees violates her first amendment rights.
The U.S. Supreme Court has taken her side.
But it limited its decision to non-traditional public employees-- like home care workers, who are paid by the state but hired and fired by the people they care for.
Paul Kersey works for the Illinois Policy Institute which helped bring the case.
He says today was a big win, but there’s more to be done.
"The Supreme Court did leave the door to reconsidering government employee union dues in general," Kersey said.
Pro-union home care workers say the union has helped raise wages. And provided better training on how to care for people.
The union says the ruling is a setback but it will continue to fight for home care worker rights.
