At my middle school, we're splitting our band between the band hall and adjacent choir hall, and pulling out small groups into another small rehearsal room each day. Even with all that, we can only space out 3 feet for some, 2 for others. We have those band masks with the slit in the middle, but they're so frustrating to use that most just end up pulling it to their chin. When students have gotten quarantined, admin hasn't asked me about my class, so I guess they aren't worried about it.
I do believe that if you're not even trying to enforce the masks or distancing when possible, you need to find another career. If you're in a school where not enforcing those things is normal across the board, its likely not a place you need to stay at.
And don't even get me started on these freaking football games
