Set your expectations in a healthy way and let other people know of it clearly. If you don’t want to answer messages you receive right away, then don’t.

Only between the time I start and stop working in a day, will I answer calls or messages for work. While I’m at work, anyone outside of work shouldn’t expect a response for several hours, or until I end work.

There are many times I’m available to respond to my friends and family (while shitposting on Lemmy being one example), others I will ignore notifications when I’m doing my own thing or talking with people irl. That takes precedence.
