St. Paul students will be out of school “in the indefinite future, as it stands right now.” That was the message from district superintendent Joe Gothard on Tuesday, day one of the teachers’ strike. Some 3,600 educators are striking; 37,000 students don’t have classes. The main sticking point was getting more mental health services for students, plus more multilingual interpreters and special education funding.

The teachers’ union president says striking wasn’t an easy decision for teachers. "Educators want to be with their students. But they also want their students to enter schools that are supported and have the resources our kids need to thrive,” Nick Faber said.
