The teachers union's threat to strike has closed Shaler Area schools on Tuesday, district superintendent Wesley Shipley has announced.
Teachers threatened to strike that day, the first day of classes for students, if a new contract is not yet settled.
The previous contract for the district's 390 teachers and other professionals expired in June 2011. The two sides met for seven hours Wednesday night.
The next negotiation session is set for Monday morning.
Mr. Shipley said earlier he did not want parents and students to leave for the holiday weekend unsure about whether school would be held Tuesday. So he decided to cancel and issued a statement this afternoon.
If an agreement is reached over the weekend, school will resume Wednesday.
Negotiation updates will be available on the district's website.
