Why don’t schools use any type of protocol for preventing sickne

Lower Township - Why don’t schools use any type of protocol for preventing sickness? Sure no one wants masks which is fine . But how about an ounce of precaution and keep around a few good things we learned from Covid. But no let’s just cram everyone in, share snacks , blast the heat with the windows closed and spread all that good stuff. Then let’s yell and threaten parents when the kids are absent. Schools have learned nothing. Just bury your hand in the sand and pretend it isn’t an issue . We could be doing so much better .
