This change.org petition to keep the schools in NYC closed is out there. I signed and encourage everyone to do the same.
As for going into a school building for elementary school teachers and other staffers on Monday, my recommendation is to stay safe and stay home if you don't believe your building is safe. Don't worry about retribution from the DOE or losing CAR days. We've explained over and over how you can rationally argue that you have a right to a safe work environment and these schools are not safe.
