"In 2009, Illinois Gov. Pat Quinn issued an executive order that said a group of Illinois residents who participate in a state Medicaid program for the developmentally disabled would be considered state workers for the sole purpose of unionization. Government unions (public employee unions) would then be able to force participants in this program to pay union dues as a condition of receiving help from the state."
