Naperville Unit Education Association President Dan Iverson speaks to a crowd of union members and supporters outside of Naperville North High School Monday. Iverson and the union have said they may not return to their classrooms for the first day of school Aug. 19 if the two sides do not reach an agreement on a new contract after the current one expired this summer.
