Open Slack threads look like unfinished chores. You sit for focus, glance at the badge, and lose the first ten minutes replaying half replies. Close open Slack threads before the focus sit starts so the chair meets one job.
Closing does not mean answering everyone. It means the thread is either done, parked with a return note, or muted until the block ends.
Audit the threads that still own you
Scan only threads where you are mentioned or you started a reply. Mute channels that are noise. Keep the list under five. If you need more, you are not ready to sit.
Pair this with say the next three steps out loud before focus so the sit starts with verbs, not inbox guilt.
Park replies with a one-line return note
For threads that need you later, write one line in your notes: who, what, and when you will answer. Do not draft the full reply now. Full drafts become a second work block.
Use the same spirit as write a return line before you leave deep work: protect the next typed burst.
Mute or leave before the timer starts
If a thread is informational, mute it. If you are not needed, leave. Soft social pressure is not a focus plan. Status colors can wait.
Set a hard reopen rule
Reopen Slack only when the focus timer ends or when a true blocker arrives. A ping is not a blocker unless the sit depends on that answer. Write the blocker on paper if you must remember it.
Worries that are not Slack can go on paper with park one worry on paper before deep work.
Cap related research the same way
Thread cleaning often opens docs and tabs. Keep cap research tabs at five so cleanup does not become a rabbit hole.
Train on short sits first
Practice on twenty-minute sits for a week. Count how often you reopen Slack mid-sit. Lower that count before you chase ninety-minute fantasies.
Keep a parking note beside the keyboard
One sticky holds the parked thread owners for this sit. Cross them off after the timer. Empty sticky means you earned a short break, not a new inbox tour.
If the sticky fills again mid-day, your role may need scheduled support windows instead of endless soft availability.
FAQ
Does close mean mark as read?
Only if you truly finished. Prefer archive, mute, or a parked note over fake-read.
What about urgent DMs?
Define urgent as a sit blocker. Everything else waits for the timer.
Can I keep Slack open in another desktop?
No. Visible badges still pull attention. Close the app or hide the workspace.
What if my role is support?
Schedule support windows. Focus sits need a closed door or they are not focus.
How many threads is too many?
More than five open owners means you need a triage pass before sitting.
