HUNTLEY – The attention on monthslong negotiations between District 158 and its teacher union now shifts to Monday, as 600-plus teachers prepare to vote on a tentative contract agreement.

The agreement was reached between union leaders and the board just after midnight Wednesday. The two sides negotiated for almost five hours during an impromptu bargaining session, hours after the union declared a formal impasse in contract talks that began in the summer.

The agreement, both sides said, more effectively addresses teacher compensation issues, even though neither side disclosed any details – something they have refrained from doing since a third-party mediator was requested in August.
