The union’s current contract expires at the end of this month.
The agreement would have seen union members given a 3.7 percent salary increase in the next school year.
It also, according to the school district, would have reduced class size to 24:1 in transitional kindergarten and kindergarten, increased flexibility in using leave time, provided adjusted prep times to kindergarten teachers transitioning to a full-day program, and provided a process by which class size overages would be addressed.
In prepared remarks, AEA President Audrey Hyman said that “new language about class overages was a point of contention.”
Roughly 70 percent of AEA members who cast a vote did so in opposition to the tentative agreement.
Bargaining is expected to resume in September.
