I work in a public school (thank me later), and we have constant pd classes on safety and vigilance. Never, never would we prop open a door, even if it is sweltering or if we needed air. The only time we prop open doors is to let students in or out during arrivel or dismissal. We have the “man trap” system at our school also, we can only enter one area if the entrance behind us is closed.
We also had a very realistic pd active shooter simulation at our school, which helped us identify weak areas. And quite a few of my colleagues are gun owners, and agree on the ridiculousness of the gun free zone thing. We don’t have that here.
My school is located in a very wealthy blue area, btw. But, we still have some common sense left.
I wonder if this district just relaxed the rules bit by bit, because of the lack of school shootings in prior years?
When I was a kid it was a regular occurrence for teachers to prop open the classroom doors and windows the last month of the year to let fresh air inside on the warm, Spring days. It was a treat for the kids after a long year of school. Of course, this was the 1970s and 1980s when the country wasn’t so f***ed up like it is today.
It sounds like your school has taken the right steps to keep you all safe.
