Why does Slack show me as away when I'm working?

You've been heads-down for two hours — writing code, in a call, deep in a doc — and a colleague pings you with "you around?" because your dot went grey. The frustrating truth: Slack isn't measuring whether you're working. It's measuring whether you're touching Slack. Those are very different things, and the gap between them is exactly why focused workers get marked Away the most.

What Slack actually counts as "activity"

Slack doesn't know whether you're working. It only knows whether your hands are on the computer. Slack's own rule is 10 minutes of desktop inactivity, and in the desktop app that means keyboard and mouse input anywhere on the machine:

• Typing or clicking in any app, including your editor, browser or email, while the Slack desktop app is running
• Moving or scrolling the mouse
• Anything you do inside Slack itself
• Being connected to a Slack huddle, even with your hands off the keyboard

Notice what's missing: the parts of real work that don't involve input. Sitting in a Zoom call, reading a long document, reviewing a design on screen, thinking through a problem, or talking to someone at your desk. Ten minutes of any of those looks exactly like ten minutes away from your desk. For the full breakdown of how the system decides, see how Slack knows you're active.

The 10-minute timer on desktop

On the desktop app, Slack gives you a grace period: after roughly 10 minutes with no keyboard or mouse input, it flips your dot from green to grey and marks you Away. The timer resets every time you touch the computer, so a day of typing mostly keeps you green. But a 45-minute call where you just listen, or an hour reading a spec, is plenty to tip you over, which is why the moments you're most engaged are often the ones Slack shows you as gone. The exact mechanics live in our guide to the Slack inactivity timeout.

Mobile is far less forgiving

If you think desktop is strict, mobile is brutal. The Slack mobile app considers you active only while the app is open in the foreground. The instant you switch apps, lock your phone, or the screen times out, Slack starts treating you as away — there's no 10-minute cushion. This is why people who "work from their phone" still show grey: the phone is in their pocket, the app is backgrounded, and Slack sees nothing.

The browser-tab trap

One of the most common reasons people get marked Away while clearly typing all day: they use Slack in a browser tab, not the desktop app. The desktop app counts input anywhere on your computer, but a Slack tab generally only notices activity inside that tab. If your work happens in other windows, the tab sees nothing and quietly sets you to Away. Where Slack sits on screen doesn't matter with the desktop app, so a second monitor on its own isn't the problem, a browser tab on it is. Installing the desktop app is usually the whole fix.

Focus modes, sleep, and lock screens

A few more silent culprits:

• macOS / Windows sleep. When your machine sleeps — even briefly — the Slack client disconnects and you go Away. Step away for coffee and you're grey before you're back.
• Closed laptop lid. A closed lid sleeps the machine. Slack can't signal activity from a sleeping computer, so you drop offline entirely.
• Focus / Do Not Disturb modes. These don't directly set you Away, but they often pair with you ignoring Slack for long stretches — which lets the inactivity timer run out.

If your dot is getting stuck grey even after you come back and click around, that's a different problem — see why Slack presence gets stuck and how to fix it.

Does it matter? What people actually see

Here's the reassuring part: Slack never sends a notification when you go Away. No ping fires to your manager, no email, no DM. The dot just changes colour, and someone has to be actively looking to notice. We cover this in full in does Slack notify your manager when you're away. The problem isn't surveillance — it's the implication. A grey dot reads as "not working," even when you're the one putting in the deepest hours. In async and remote teams, presence becomes a proxy for effort, fairly or not.

How to stop it — from worst to best fix

1. Manually set yourself Active. Click your avatar → "Set yourself as active." Works until the next inactivity reset, then reverts. Tedious and unreliable.
2. Keep clicking Slack. The "wiggle the mouse over Slack every 20 minutes" approach. It works and it's free, but it pulls you out of focus constantly — the exact thing you were trying to avoid.
3. Mouse jigglers / caffeine apps. These keep your machine awake so the desktop client stays connected. They fail the moment you close the lid, the laptop sleeps or the screen locks. See mouse jiggler vs always-active app.
4. A cloud presence service. The only approach that fully decouples your green dot from your attention. Stay Green On Slack connects to Slack from the cloud and signals activity every 60 seconds, on a schedule you choose — so you stay green during your working hours even with your laptop closed, and appear normally away outside them.
