PORTLAND, Ore. (KOIN) — Another round of all-day negotiations in the first-ever Portland teachers strike continued Sunday, but no deal was reached. And at 7 p.m. Sunday, PPS Superintendent Guadalupe Guerrrero announced classes were canceled for Monday.

“We will continue to work late into this evening (Sunday), but given where we are in the negotiations, and PAT’s confirmation that they intend to remain in a work stoppage, there will be no school tomorrow (Monday, November 6),” Guerrero said in a statement.

“We are prepared to continue meeting again tomorrow (Monday) and are hoping PAT will stay with us at the table.”

Initially, PAT said there would be no bargaining sessions on Monday, but late Sunday night said “bargaining will resume” Monday afternoon.

PAT President Angela Bonilla on Saturday said the union was ” encouraged by the improved dialogue on key issues in negotiations,” but said the district “has a long way to go to get our students what they need, settle this contract and get educators and students back into the classrooms.”

The teachers’ union said picketing will continue early Monday.

PPS officials said that negotiations will last late into the evenings and will alert parents by 9 p.m. each night about whether classes will be canceled the following day.

Teacher pay, planning time and class sizes are among the biggest issues on the table.

“We will work as much as we need to arrive at a fair settlement that honors their work, but also make sure we’re fiscally responsible to continue to operate a premier school system in Oregon,” PPS Superintendent Guadalupe Guerrero said.
