How to Say ‘I will be late’ at Work
Telling your manager or team that you will be late can feel awkward, but the right phrase makes all the difference. The direct answer is simple: instead of just saying “I will be late,” use a polite opener like “I wanted to let you know that I am running behind” or “I apologize for the delay, but I will be arriving a bit later than planned.” This shows respect for their time and keeps the conversation professional.
Quick Answer: Polite Phrases for Being Late
If you need a fast, polite way to say you are late at work, use one of these phrases:
- “I wanted to let you know I am running a few minutes late.”
- “I apologize for the inconvenience, but I will be arriving shortly.”
- “I am running behind schedule and will be there as soon as I can.”
- “Just a heads-up that I am delayed, but I am on my way.”
These phrases work for both spoken conversation and quick messages. They are direct without being rude.
Why Word Choice Matters When You Are Late
Being late happens to everyone, but how you communicate it affects how others perceive you. A blunt “I’m late” can sound careless or dismissive. A polite version shows that you value the other person’s time and that you take responsibility. In a workplace, this small difference builds trust and respect.
Consider the context. If you are sending an email to your boss, you need a more formal tone. If you are texting a coworker, a casual but polite phrase works better. The key is to match your language to the situation.
Formal vs. Casual Ways to Say ‘I Will Be Late’
Below is a comparison table that shows the difference between formal and casual phrases. Use this as a quick reference when you need to choose the right tone.
| Context | Formal Phrase | Casual Phrase |
|---|---|---|
| Email to manager | “I apologize for the delay. I will be arriving at the office shortly.” | “Hey, running a bit late. Be there soon.” |
| Team meeting | “I regret to inform you that I am running behind schedule.” | “Sorry, I’m stuck in traffic. I’ll be there in a few.” |
| Client call | “Please accept my apologies. I will join the call as soon as possible.” | “My apologies, I’m a little late. I’m dialing in now.” |
| Slack or chat | “I wanted to let you know that I am delayed due to an unexpected issue.” | “Running late! See you in 10.” |
Natural Examples for Real Situations
Here are natural examples you can adapt for your own messages. Each example includes a brief explanation of why it works.
Example 1: Email to Your Manager
Subject: Running a few minutes late this morning
Dear [Manager’s Name],
I wanted to let you know that I am running a bit behind schedule this morning due to an unexpected delay on my commute. I apologize for any inconvenience and will be at my desk within the next 15 minutes. Please let me know if there is anything urgent I should address as soon as I arrive.
Best regards,
[Your Name]
Why it works: This email is polite, gives a reason without over-explaining, and offers a solution. It shows responsibility.
Example 2: Quick Message to a Coworker
“Hey [Name], just a heads-up that I’m running about 10 minutes late for our meeting. I’ll be there as soon as I can. Thanks for understanding!”
Why it works: This is casual but still polite. It uses “just a heads-up” to soften the news and thanks the person for their patience.
Example 3: Voicemail or Phone Call
“Hi [Name], this is [Your Name]. I’m calling to let you know that I am running a little late for our appointment. I apologize for the delay and will be there shortly. Please call me back if you need to reschedule. Thank you.”
Why it works: This is clear and professional. It offers an alternative (rescheduling) so the other person feels in control.
Common Mistakes When Saying You Are Late
Even polite phrases can sound wrong if you make these common mistakes. Avoid them to keep your message professional.
Mistake 1: Over-apologizing
Wrong: “I’m so, so sorry. I’m really, really late. I feel terrible.”
Why it is a problem: Too many apologies can sound insincere or desperate. It also wastes time.
Better: “I apologize for the delay. I will be there shortly.”
Mistake 2: Giving Too Many Details
Wrong: “My car wouldn’t start, then I had to wait for the bus, and then the bus was late, and then I spilled coffee on my shirt.”
Why it is a problem: Too much information can seem like an excuse. Keep it brief.
Better: “I am running late due to an unexpected issue. I will be there soon.”
Mistake 3: Being Too Vague
Wrong: “I’ll be late.”
Why it is a problem: This gives no information about how late or why. It can seem rude.
Better: “I am running about 15 minutes late. I will update you when I am closer.”
Mistake 4: Not Offering a Solution
Wrong: “I’m late. See you when I get there.”
Why it is a problem: It leaves the other person waiting without knowing what to do.
Better: “I am running late. Please start the meeting without me, and I will join as soon as I can.”

Frequently Asked Questions
1. Should I always apologize when I am late?
Yes, a brief apology shows respect. But keep it short. One “I apologize” or “Sorry for the delay” is enough. Do not repeat it multiple times.
2. Is it okay to say “I am running late” instead of “I will be late”?
Yes. “I am running late” is more common and sounds more natural in English. It is also slightly softer than “I will be late,” which can sound more final.
3. How much detail should I give about why I am late?
Give a brief reason if it helps, but do not over-explain. A simple “due to traffic” or “due to an unexpected issue” is enough. Too many details can sound like an excuse.
4. What if I am late every day? Should I change my phrase?
If you are often late, the phrase is not the main problem. You need to address the habit. In the meantime, use phrases that show you are aware, such as “I apologize for being late again. I am working on improving my schedule.”
