At a press conference on an unrelated topic Wednesday, the mayor said he and Byrd-Bennett already are working out how to carry through on a pledge that every child who is moved ends up at a higher quality school. He said the closings already have been delayed too long."Keeping open a school that is falling short year-in and year-out means we haven't done what we are responsible for; not what our parents did for us and what we owe every child in the city of Chicago," Emanuel said. Critics say the closings disproportionately affect minority neighborhoods and will uproot kids who need a stable and familiar environment in which to learn. They also worry that students will have to cross gang lines to get to a new school, and that the vacated buildings will be blight on already struggling communities. Jonathan Hollingsworth III, a lunchroom manager at CPS, said he's also concerned that the plan will leave hundreds of workers jobless. He said he voted for Emanuel but won't do so again. "He's downsizing everything in the damn city. It's take it or leave it," Hollingsworth said. "Keep this in mind: Come election time, all of these people will have the last laugh." Opponents of the plan will get another chance to argue their case at a series of public meetings that will be scheduled in coming weeks, though the Chicago Board of Education â¿¿ whose members are all appointed by Emanuel â¿¿ is expected to approve the closings in late May. The closings would take effect beginning at the start of the 2013-2014 school year.
