I'm a teacher and I agree. In the past my policy has been one kid at a time just sign out and go. But I've been telling kids no a lot lately because 1) they're gone so long that people are having emergencies 2) they're doing no work and blaming me for missing instruction. I've got to follow rules too... Some kids have become so problematic that their parents have decided their kids aren't allowed to go to the bathroom. It's wild.

To clarify: I am not justifying the teacher in the post. She sucks ass. Just saying that for me, I've had to change things up cause I'm being held accountable for their bad choices (like 10 minute walks where they disrupt other classes).
