would it bother you if a coworker posted a group photo, that you were in, on their social media without asking you?

I'm always terrified of someone taking a photo of me without my permission in public.

Since it says I’m not tagged it fine

If you are posing for a picture these days, you must assume it will be on social media

Why not

All they have to do is ask

It would be a reason to break contact right away.
