High school seniors were excused from final exams and will graduate Wednesday, but the school year will be extended to about June 27 for all other students.
The teachers, guidance counselors, librarians, and nurses have been working without a raise for nearly four years, under a contract the school board says it can no longer afford.
The union called off the strike during a hearing before Bucks County Court Judge Robert O. Baldi. The judge, responding to state Department of Education requests for injunctions to end the strike, ordered the teachers back to work by Friday.
The NFT then offered to halt the six-day strike "immediately, as an act of good faith," a union spokesman said.
But Webb and district labor lawyer Charles Sweet said schools could not reopen until Wednesday.
"It's for the children's safety," Webb said after the hearing. "We need to get the air-conditioning running in the schools that have it, and we need to bring in food."
NFT president Louise Boyd responded in a statement by accusing the district of "unnecessarily" prolonging the school year by another day, "and that's unfortunate."
By ending the strike, the union expected to return to the negotiating table Tuesday, Boyd said. But that session will be canceled, Webb said, because "technically, they're on strike and the schools are closed."
The board has refused to negotiate while the union is on strike.
The district has presented six dates for negotiating sessions, from June 26 to July 30, Webb said, subject to the availability of the union and the state mediator overseeing the talks.
"This will give us time to prepare a new proposal," Webb said. "Hopefully, we'll get all six dates."
Both sides are scheduled to return to court on June 25, for Baldi to consider ordering court-supervised negotiations, Webb said.
