When to send it
Send it before your start time, as soon as you know. The same message sent after you should have arrived lands very differently. If you have a 9 a.m. meeting, tell the organizer too.
Three things to include
- One line of fact — why you’re late. Don’t over-explain.
- Arrival time — "arriving 9:40" beats "running a bit late".
- Your plan — what happens to the meeting or urgent task.
Example messages
| Situation | Example |
|---|---|
| Train delay | Hi Sam, my train is delayed and I’ll be in around 9:30. Please start the 9:00 without me and I’ll join as soon as I arrive. |
| Childcare | Hi Sam, a problem with school drop-off means I’ll be in at 10. The morning report will still be with you by 11. |
| Unwell | Hi Sam, I’m not feeling well and am seeing a doctor first; I expect to be in by 11 and will keep an eye on chat for anything urgent. |
Phrases to avoid
- "Running a bit late" — no idea how late
- A long backstory — reads like an excuse
- Messaging after you’re already late — the most common mistake

Rewrite
Rewrite on the result card turns the same line into To your boss, To a coworker or Chat style. Once a day is free; after that, one ad per extra use.
