AFK meaning: AFK stands for “away from keyboard.” At work, people post it in chat to say they are stepping away from their computer for a short time and won’t reply right away. It started in online gaming and chat rooms and is now common in Slack, Microsoft Teams and other workplace chat tools.
What does AFK mean at work?
AFK is a quick status update. When a coworker types “AFK” or “going AFK,” they are telling the team they have stepped away from their desk or laptop. They might be grabbing lunch, taking a call, picking up a child from school or just stretching their legs.
The key idea is temporary. AFK usually means minutes, not hours or days. If someone will be gone for the rest of the day, they normally say they are offline, out of office or signing off instead.
AFK is informal. It fits team chats and direct messages between people who work closely together. It is less suitable for emails to clients, senior leaders you rarely talk to, or anyone outside your company who may not know the term.
When someone comes back, they often type “back” or “BAK” (back at keyboard) so others know they can reply again.
Examples of AFK in emails and messages
Slack: “AFK for 15 minutes, grabbing lunch. Ping me if the build fails.”
Teams group chat: “Going AFK for a quick call with the vendor. Back by 2:30.”
Direct message: “Sorry for the slow reply, I was AFK walking the dog.”
Status message: “AFK – school pickup, back at 3:45 p.m. ET.”
Team channel: “Back from being AFK. Catching up on the thread now.”
Notice that the best examples add how long you will be away. “AFK” on its own leaves people guessing.
AFK vs BRB vs OOO
These three are easy to mix up. They all say “I’m not available,” but they differ in how long you will be gone.
| Term | Stands for | Typical length | Best used in |
|---|---|---|---|
| AFK | Away from keyboard | A few minutes to an hour | Team chat, status messages |
| BRB | Be right back | A few minutes | Casual chat with close coworkers |
| OOO | Out of office | Half a day to several weeks | Email auto-replies, calendars, status messages |
A simple rule: use BRB for a two-minute break, AFK for a short absence, and an out-of-office status (see OOF and OOTO) when you will be gone for most of a day or longer.
How to use AFK correctly
- Add a return time. “AFK until 1:15” is far more useful than “AFK.” If your team spans time zones, include yours.
- Say how to reach you if it is urgent. For example: “AFK for 30 min, call my cell if the client calls.”
- Match your chat status. Set your Slack or Teams status to “Away” so people see it without reading the thread.
- Keep it to internal chat. In client emails, write it out: “I’ll be away from my desk until 2 p.m.”
- Don’t overuse it. You don’t need to announce every coffee refill. Use AFK when someone is likely waiting on you.
- Post when you are back. A quick “back” closes the loop and tells people they can expect replies again.
When to avoid AFK: in formal emails, with customers, with new hires who may not know chat slang, and in any message where being misunderstood could cause a problem. In those cases, plain words like “I’m stepping away until 3 p.m.” work better.
