(CBS) — Negotiations continued late Thursday amid an atmosphere of optimism, in the strike by teachers at McHenry High School District 156.

The two sides are sitting down for the first time since a nearly nine-hour session that ended at 4:10 a.m. Wednesday.

The latest statement from District 156 said two things: that talks are resuming, and a reminder to parents that they could get a call day or night telling them school is reopened. Classes were canceled for Friday, however.

Union spokesperson Heidie Dunn sees optimism.

“I think there is tonight a very real possibility that we could get this settled,” she told WBBM Newsradio.

Pay and healthcare benefits have been the two major stumbling blocks.

Friday night’s Homecoming Dance is being rescheduled.

As CBS 2’s Brad Edwards reports, Friday’s previously scheduled homecoming football game is a casualty of the strike.
