I don’t want you to shout “shut up.” It’s no big deal either. Your teacher won’t be disciplined or terminated for this unless you have a very irresponsible or retaliatory administration. It is quite possible that the teacher didn’t say “shut up” at all, but that’s how the kids used it.
If the teacher actually said “shut up,” you should tell her that you think this is unacceptable and that repeating it will lead to your information as the principal of the matter. Ask them to use more lenient language in the future. Theatre teachers probably need to berate kids to keep them informed. You have too many students walking around everywhere, and there’s a show, and the theater teacher gets fired if the performance isn’t good.
When a performance (and a job) is at stake, the teacher should be allowed to curse. Yes, in some cases it’s not appropriate and when teachers say it they have to be careful not to favor just one or two students. I even think that when a teacher is having a bad day and is aware that they are more intolerant, they try even more cautiously to keep them together. To say the least, I wasn’t my teacher’s favorite student and she didn’t hide it any more than I did.
If you’re irritated, this is probably the last thing you want to do, but your teacher won’t respond well to arguing, yelling, screaming, or insults. Leave the room calmly, quickly go to the bathroom and enter the room silently. If your teacher says “no” or “, wait a moment, ask again later. I usually teach children who are much younger and don’t dream of hurting their sensitive little devil hearts by telling them to shut up. I usually use other methods, including stopping and looking (less effective on masks as they can only see my eyes and eyebrows and they think I can’t tell they’re talking when I can’t see their mouth), but shut up is sometimes just the most effective option with this group .
You’re the adult in the room, so I’d say, “Shut up is a bit below you, but you can always hit them with phrases with the same meaning that are more professional. Yes, your teacher can “force” you to give a presentation, and if you refuse (or conveniently “forget” to tell her you “couldn’t get to school”), she can give you a failed grade for the course. When I was in 3rd grade, my teacher called me something that translates narrowly as “someone stupid,” but still offered to present because I made a mistake. Eventually I felt it was better to yell at her to sit down and shut up, which seemed to catch her off guard and got a better result than sending her to the director for an official replay.
I’m a teacher and there have been times when I’ve been “unprofessional” but of course I never go to work and think about it — I’m going to curse someone’s child today, not even if you know it’s a class where students really push your buttons. Some teachers use this as a form of non-verbal communication to tell their students to get back to work.
