An ongoing issue for the union has been its demand that the city give schools more surplus money from tax increment financing districts. Emanuel has established a policy of declaring as surplus 25 percent of yearly TIF revenue not committed to a specific project or program. This year, he has committed to a surplus of at least $60 million, with $32.5 million going to CPS, but the figure is expected to be higher in the mayor's proposed budget to be announced Tuesday.
