CHICAGO — The president of the Chicago Teachers Union says teachers and the school district are still far apart in their contract dispute and that the walkout will almost certainly extend into a third day on Wednesday.

Representatives from the union and the district returned to the bargaining table Tuesday, but union President Karen Lewis says only six of 48 articles in the contract have been resolved.

She says it's "lunacy" to think a settlement could be reached Tuesday. School board officials insisted the two sides should be able to make an agreement.
