When I first started working, I would respond outside of working hours, work overtime, and try to please everyone. As I got older, I developed a rule: as soon as I finish work, I just ignore all work chats, calls, and emails. Did it affect my well-being? Yes, I highly recommend it to everyone!
Seriously, just don’t install (or log in to) Slack on your phone. Started doing this myself a few years ago and it has been great. I have a pager, page me if you need me. It’s just… normal to not be obsessed with work.
And/or: Have separate work and personal devices and never cross the streams. When I'm done working on Friday, I put my work laptop and work phone in a soundproof drawer and don't open the drawer until Monday morning.
At the very least don't install work Slack on your personal phone!!
