Workers are expected to halt construction on a state-funded charter high school facility being built on Chicago's Southwest Side for the state’s largest charter-school operator, the United Neighborhood Organization. The Chicago Sun-Times says the move comes five days after Illinois Gov. Pat Quinn suspended funding to UNO following disclosure of deals that state officials say violated terms of a $98 million state grant. The general contractor on the high school, Wight & Co., informed UNO that construction would stop Tuesday afternoon. The company says UNO has fallen behind in its payments for work on the high school.
