One thing I've struggled with in the past is employers who seem to expect 8 hours of solid productivity a day if I'm remote.
When I was in the office, it was easier to say "well sorry, I've followed up twice in 3 days on issue x, and unfortunately you got back to me after I'd left for the weekend".
When I'm remote, since there is the flexibility to stop and start work, but that seems to come at the expense that when doing work that requires collaboration, someone can delay responding on something that's a block, and then there's some pressure to "make up" for the "unproductive" time. You don't get any good grace for "being present" and there's less of the social aspect. (If I had downtime in an office, I might make some tea and ask a coworker about their kids/hobbies, a random slack DM feels intrusive)
How did you handle this issue? Did you just establish "core hours" you are available?
I've encountered similar issues in non-remote workspaces, and it's something I'm keenly interested in. I am not a lazy person, but I desire a delineation between "work time" and "personal time", and struggle to set that boundary without seeing my career struggle.
