ST. PAUL, Minn. (AP) — Negotiations continue in an effort to avert a teachers’ strike set for Tuesday in the St. Paul School District.

The St. Paul Federation of Teachers says talks were underway Sunday and will continue Monday, if necessary. But the union says teachers are ready to hit the picket lines Tuesday morning if there’s no agreement by then. The district has about 3,200 teachers and nearly 37,000 students.
