I dont mind if it does. There are plenty of people who prefer to work from home and are more productive in doing so. I'm certainly not one of them. Just like you, I prefer the mental divide.

As for you coworkers, I would simply set fixed working hours, like in the office, and put that into calendar, skype, teams, what have you and close everything else. Thats when you stop work and are not reachable anymore.

I had the same issue as you. Got called at 8pm about a project on my private number (massive mistake handing that out to someone work related). Told them I'm not working right now, reach me under my work phone from 9-5 and call back then. Don't even allow for discussion.
