Buses get delayed. Trains stop. Children get sick. Traffic happens. Running late for work is normal — and it happens to everyone in the UK at some point.
What matters is how you tell your manager. A clear, polite message takes 30 seconds and protects your reputation. Saying nothing — or sending a confusing message — can cause real problems.
This guide gives you the exact phrases to use, whether you’re texting, calling, or messaging on WhatsApp.
AI Quick Answer
If you’re running late for work, message your manager as soon as you know. Use three parts: a brief apology, the reason, and your new arrival time — for example, “Hi Sarah, the bus is delayed. I’ll be in by 8:30. Sorry.”
This guide teaches you the AWARE Formula — a proven structure for explaining mistakes at work with confidence. Learn it once, use it everywhere.
📌 Quick Summary
- Tell your manager as soon as you know — don’t wait until you’re already late.
- Use this simple structure: Apology + Reason + New arrival time.
- Keep it short. One or two sentences is enough.
- Phone calls are best for serious lateness. Texts are fine for 10–15 minutes.
- Apologise once when you arrive — then move on.
Why Telling Your Manager Quickly Matters
In UK workplaces, managers do not usually get angry about being late. They get frustrated about not knowing.
When you message early, your manager can:
- Move someone else onto your task
- Cover your station, shift, or patient
- Tell the team or the customer
- Plan the day properly
A quick message shows you are reliable and professional, even when things go wrong.
Useful Phrases to Tell Your Manager You’re Late
For a short delay (5–15 minutes)
“Hi [Name], I’m running about 10 minutes late — the bus is delayed. I’ll be there as soon as I can. Sorry.”
“Morning [Name], traffic is bad today. I should be in by 8:15. Apologies.”
For a longer delay (30+ minutes)
“Hi [Name], my train has been cancelled. I’m waiting for the next one — it should arrive at 9:30, so I’ll be at work around 10:00. I’m really sorry.”
“Hi [Name], there’s been an incident on the motorway. I’m stuck in traffic and I’m not sure exactly when I’ll arrive. I’ll update you as soon as I know more.”
For a personal emergency
“Hi [Name], I’ve had a family emergency this morning. I’ll be in as soon as possible — probably around 11. Sorry for the short notice.”
“Hi [Name], my child is unwell and I need to drop them at my mum’s. I’ll be about an hour late. Sorry.”
When you don’t know your arrival time
“Hi [Name], I’m going to be late but I’m not sure by how much. I’ll text again in 15 minutes once I know more.”
Step-by-Step: What to Do When You’re Running Late
Step 1 — Message as soon as you know
Don’t wait until your shift has already started. The moment you realise you’ll be late, send a message. Even if you’re not sure how late, send something.
Step 2 — Use the right channel
Use the channel your workplace prefers:
- Phone call — best for serious lateness (30+ mins) or care/safety roles
- WhatsApp / text — fine for 5–20 minute delays in most workplaces
- Team app (Teams, Slack) — used in offices and some warehouses
Step 3 — Use the 3-part formula
Every late message should have three parts:
- Brief apology — “Sorry” or “Apologies”
- Short reason — “Bus is delayed” / “Traffic” / “Family emergency”
- New arrival time — “I’ll be in by 8:30”
Step 4 — Apologise once when you arrive
When you walk in, say a short “Sorry I’m late — thanks for your patience” to your manager. Then get to work. Don’t keep apologising all morning.
🎬 Real Workplace Scenario
Situation: Maria works in a care home. Her morning shift starts at 7:00. At 6:30, her bus doesn’t arrive. The next one is at 7:10.
She calls her manager Lisa at 6:35:
“Hi Lisa, it’s Maria. My bus didn’t arrive and the next one is at 7:10. I’ll be at the home by about 7:35. I’m so sorry — can someone cover Mrs Wilson’s morning medication until I get there?”
Lisa’s response:
“Thanks for calling, Maria. I’ll ask Tom to cover until you’re here. Travel safe.”
✅ Maria called early, gave a clear time, and thought about the patient. This is exactly how it should be done.
✅ Running Late Checklist
Before you send your message, check:
- ☐ Did I message as soon as I knew?
- ☐ Did I include a short apology?
- ☐ Did I say why (briefly)?
- ☐ Did I give a new arrival time?
- ☐ Did I use the right channel (call vs text)?
- ☐ Is my message polite and short?
⚠️ Common Mistakes to Avoid
❌ Wrong: “Sorry I’m late.” (sent at 9:30 when shift started at 9:00)
✅ Better: “Hi [Name], I’m running 20 minutes late — bus is delayed. Sorry.” (sent at 8:45)
Send the message before you’re late, not after.
❌ Wrong: “I might be a bit late maybe sorry not sure.”
✅ Better: “I’ll be about 15 minutes late. Sorry.”
Be clear and specific. “Maybe” makes managers anxious.
❌ Wrong: Long explanation about every detail of the traffic, the bus driver, the weather…
✅ Better: “Traffic is bad — I’ll be 30 mins late. Sorry.”
Your manager is busy. Keep it short.
❌ Wrong: Saying nothing and hoping no one notices.
✅ Better: Always send a message, even if you’re only 5 minutes late.
Silence is the biggest mistake. It damages trust.

💡 Expert Note: The UK “Patience” Phrase
In UK workplaces, you’ll often hear the phrase “Thanks for your patience” instead of repeating “sorry” many times.
When you arrive, try saying:
“Sorry I’m late — thanks for your patience this morning.”
This sounds confident and professional. It acknowledges the situation without over-apologising — which UK managers respect.

Frequently Asked Questions
Should I call or text my manager?
For short delays (under 15 minutes), a text or WhatsApp is usually fine. For longer delays, or if you work in care, healthcare, or safety-critical roles, call. If you’re not sure, call — a phone call always shows more respect.
Do I need to give the full reason?
No. A short reason is enough — “bus delayed”, “traffic”, “family emergency”. You don’t need to explain every detail. Managers respect short, clear messages.
What if my English is hard to write quickly in the moment?
Save 2–3 ready-made messages in your phone notes. Copy and paste, change the time, and send. Or use our Message Rewriter tool — type in any language and get a polite English version instantly.
Should I keep apologising all day?
No. Apologise once when you arrive, then work normally. Repeating “sorry” all day can actually look unprofessional in UK workplaces.
