If the public school teachers were compensated like other professionals (engineers, IT technicians, etc) the teaching jobs would be filled and interviewed competitively. There would be no need for a union to represent interests not necessarily the teachers and students. Most teachers I know in our area want nothing to do with their union. I understand that 80 percent of school funding is spent on administration, not specifically "teaching" which is a double-digit uptick from ten years ago. I submit that if the teachers were treated and compensated as professionals the cost of education would actually go down.
