ALGONQUIN – District 158 teachers have a contract for the next three years that will cost the district roughly $5.6 million, mostly in annual pay raises for teachers based on classroom experience.

The district board endorsed, 6-0, the new contract in a special meeting Tuesday. The district’s union, the Huntley Education Association, ratified the agreement Monday evening. Board President Michael Skala abstained from the vote because his wife is a district teacher.

The new contract is essentially unchanged from the district’s last three-year contract, which ran from 2008 to 2011. The new deal thaws teacher pay raises that were frozen in a one-year contract that expired in June.
