Portland Public School students are finally back in the classroom, but they’re having a very rough time. The Portland Association of Teachers  says teachers are at a breaking point: there are staffing shortages across the district, and teachers are struggling to keep up. That’s why the union wants PPS to suspend in-person high school classes one day a week for the rest of the school year and to cut some instructional time for younger students as well. But not everyone is excited about the proposal.
