(Portland, OR) -- Portland Public Schools workers are in the process of voting this week to determine whether or not they will go on strike as they continue to fight for better pay. The Portland Association of Teachers says voting started yesterday and will end on Thursday at the latest. If the strike is approved, the union will give the school district ten days notice before workers head to the picket line. In addition to higher pay, teachers are asking for more funding to increase staffing and reduce class sizes along with an increase in mental health staff for students.
