It's time to "just say no" to the small class-size pushers and eliminate seniority as a staffing mechanism.
Small class size means less work for teachers. Parents seem to think that their child will be better educated in a room with fewer classmates. Unions love fewer kids in a class because it equates to a larger workforce, which means more money and power for them. Only problem is that small class size does not lead to greater student achievement. It just means more hiring, then laying off the same teachers and punishing taxpayers who needlessly pay for a bloated workforce.
