Do you make your students take an "English name"?

You say their full name....

That works for students, but if you're addressing someone who is older or a higher rank than you, you'll be in deep 꼰대 sh*t if you call them by their full name.

In a professional setting, it's much safer to call someone by their first name with 님 on the end or their surname followed by their position. Like 동은님 or 박본부장님.

But it wouldn't be polite for a student to address a teacher by his/her given name, right? English names just didn't seem improper to us in that respect. I would like to point out this wasn't policy but just kind of happened.

Fair point that back in the day it was a lot stricter. Things are a little looser these days. I mean, surname or full name+title is fine, regardless you aren't just saying "Kim Teacher anymore". In all my years I have never heard a student address a teacher solely by family name+title. It was always "이민정선생님" or "민정샘" never "이선생님". Like, my Korean is not great, but I'm pretty sure on this.

This idea that students are walking in, saying "Kim Teacher" and everyone being confused for 10 minutes so Koreans need English names is just ridiculous.

My students call me Teacher ......... (my first name) and there is no hint of any disrespect. They do it to my Taiwanese co-teachers too, in fact my one COT always tells them to call her Claire. As I said before, Taiwanese students are really respectful so I am pretty comfortable with it. Back in SA I was called, Sir or Mr ........  In Korea, I was ............. (my first name) Teacher.  What do your students call you and how's the respect level?

At my school the policy is Mr. Familyname. At all my previous schools it was just given names when speaking English. I was more referring to addressing your teacher in Chinese. It's always 'Familyname Teacher' which can get confusing if several teachers have the same family name, especially since the title 'teacher' is gender neutral. That's why everyone at my old school, mostly Chinese students and teachers, just defaulted to English names.

I should clarify that I'm talking about coworkers (adults referring to other adults) in a corporate context, so lots of different titles, which is why you can get away with calling someone by their surname and title.

In that respect, I've taught my students to call me "Mr. (family name)". Not because I thought they were being rude, but just that I felt like getting them used to that part of my culture.

And while some coteachers have told me that it would be hard for the kids to understand, it's never actually been.

When I was a teacher in primary school  in New Zealand I did come across some schools where the students did call teachers by their first names.  Initially it seemed a bit strange but actually it worked out fine.  I relieved at a school that did that, a few times and actually didn't find it to be a problem.  Students still spoke respectfully to the teacher (well as respectfully as when they were using Mr, Miss/Mrs/Ms).

Here, in Korean Public Elementary schools, I am quite happy to have the students cally me 'Jennifer'.  It gets quite interesting though when we ask them what my family name it!  'Je' or 'Er' are the usual answers!  I don't use my surname much at school.
Half of my co-teachers don't tell the students what they should be called and the students just say 'Teacher' when they want their attention.  That is OK in class but when they come to the office looking for the teacher it is difficult to know which teacher they want - especially when more than one teacher is teaching one grade.
