You are at your desk. You are working. You are not on a beach, in the pub, or halfway through a suspiciously long lunch.
Then you glance at Slack and the green dot has vanished.
Helpful.
This happens because Slack presence is not a perfect measure of whether you are working. It is a measure of detected activity. Those are not the same thing, which is where the little green dot starts causing trouble.
Slack is looking for activity, not effort
Slack automatically decides whether you are active or away. According to Slack's own Help Centre, you are set to away after 10 minutes of desktop inactivity. On mobile, you can also be shown as away if you navigate away from the app or close it.
That sounds simple enough, but it misses a lot of normal work.
You might be reading a long document.
You might be watching a demo.
You might be reviewing a spreadsheet.
You might be thinking through something awkward before replying.
You might be working in another app for half an hour.
None of that necessarily looks like activity to Slack. Your brain may be doing cartwheels, but Slack cannot see your brain. Probably for the best.
Why Slack gets it wrong
Presence tools are built around signals. They look for things like desktop activity, app activity and whether the app is open.
That is useful most of the time. If you close your laptop and go for a walk, Slack can reasonably mark you away.
The problem is the middle ground. Remote work has a lot of quiet activity. Reading, planning, listening, comparing, checking, thinking. There is often a gap between being productive and touching the keyboard.
Slack does not know the difference between "away from desk" and "reading something painful but important". It only sees whether the right kind of activity is happening.
Common reasons Slack may show you as away
The most obvious one is desktop inactivity. If nothing is happening on your computer for long enough, Slack can mark you away.
Another common one is working in another app. If you are deep in a design file, a browser tab, a doc, a spreadsheet or a local tool, you may still be busy, but Slack may not get much activity from you.
Your computer sleep settings can also get involved. If your machine sleeps, locks, dims or pauses background activity, Slack presence can change. It can help to keep your computer awake so it does not drop into idle while you are still at your desk.
Mobile can be messy too. Slack says mobile availability can change when you close the app or navigate away from it. So leaving Slack on your phone is not a clean fix.
Things people try
Some people manually set themselves active. That works until it does not. You have to remember to do it, and Slack can still update your availability later.
Some people leave Slack open all day. That helps a bit, but an open window is not the same as activity.
Some people change sleep settings. That can stop the computer going idle, but it does not always mean Slack will keep showing you as active.
Some people use a mouse jiggler. That may create movement, but it is not very controlled. Your pointer moves, but it may not be doing anything useful.
A better way to think about it
The safer question is not "how do I force Slack to stay green?"
It is this:
How do I stop my computer looking idle whilst I am genuinely working?
That is a fair problem. If you are reading, listening, thinking or working in another app, your status can give the wrong impression. You want your desktop to stay awake and active in a controlled way.
That is where controlled desktop activity helps. Rather than leaving everything to chance, you choose a harmless safe screen area and keep activity happening there.
Where Green Dotter fits
Green Dotter is a free Mac and Windows app that lets you automate mouse clicks in a screen area you define. It is local, simple, and built for times when you are still working but your computer would otherwise go quiet.
It is useful for reading, calls, long documents, repetitive workflows, and work in other apps where your presence indicator might not reflect what you are actually doing. If you want the full walkthrough, see how to prevent Slack going idle.
Use it sensibly. Always follow your workplace policies and the rules of the tools you use.

FAQ
Why does Slack show me as away when I am working?
Because Slack uses activity signals. If your desktop or app activity goes quiet for long enough, Slack can mark you away, even if you are still reading, thinking or working elsewhere.
How long before Slack marks you away?
Slack says it sets you away after 10 minutes of desktop inactivity.
Does keeping Slack open stop away status?
Not always. Keeping Slack open can help, but an open window is not the same as active input.
Can Green Dotter help with Slack away status?
Green Dotter can help keep controlled desktop activity happening whilst you are genuinely working. It should be used responsibly and in line with workplace rules.
