(Portland, OR) -- Dozens of teachers and staff are facing possible layoffs as Portland Public Schools officials are estimating a budget shortfall of between 18-million and 23-million-dollars. The exact figure won't be known until the state budget is finalized in the coming months, but school district spokesman Dave Northfield tells Fox-12 the deficit will definitely be felt at the school level. In addition, the district is about to begin collective bargaining with the teacher's union and needs to find another five-million-dollars for potential raises. Northfield says district officials are trying to find other areas in which to make cuts.
