CHICAGO (AP) — An independent fact finder has recommended that Chicago teachers receive a 14.85 percent raise to “compensate teachers for working a longer school day and year,” a union official union said Monday.

The announcement is the latest turn in acrimonious negotiations that prompted teachers in the nation’s third-largest school district to authorize their leaders to call a strike this fall. However, Chicago Teachers Union President Karen Lewis did say whether the report would make a strike more or less likely.
