Common Sense missing from schools?

I recently visited a school (along with other teachers) and talked with them about the new building. This building had everything. Of course built in tech, projectors and other things to help like central vacuum cleaners. The advantage here is that teachers could easily and quickly clean up something if needed.

I liked the idea, some of the teachers did not. Apprenetly they had to get the okay through two unions to have them installed. Teachers did not want to be forced to clean, and janitors wanted to clean.

How about some common sense.
