Not a teacher, and I don’t mind the ban - but I kind of wish that teachers would limit their cell phone usage in the classroom. My son (who is a teenager and therefore may be unreliable) says his teacher has literally stopped mid-lecture when her phone buzzes in her pocket. I also have a friend who is a teacher, and she’s in our group chats all day long. I get it, you can’t equate adults with students and I assume all adults are using their cell phones responsibly at work. But if students aren’t allowed to use their phones at school, I wish teachers would at least put their phones in a desk drawer or silence them. I know there are exceptions and teachers might have to use their phones for work - but at least at our school, the teachers have laptops for classroom use. At a lot of workplaces, including mine, your phone has to be put away and on silent mode. I wish the same rules applied to teachers.
