Telling your manager or team that you are running behind schedule is a common workplace situation. The direct answer is that you should state the fact clearly, give a brief reason, and provide your estimated arrival time. The best way to say it depends on your relationship with the person, the method of communication (email, chat, or in person), and the company culture. This guide covers the most practical phrases for different workplace scenarios, so you can communicate professionally and maintain trust.
Quick Answer: What to Say When You Are Late
Use one of these phrases depending on your situation:
- For a direct manager (email or chat): “I am running about 15 minutes late due to unexpected traffic. I will be at my desk by 9:15.”
- For a colleague (chat or text): “Hey, running a bit late. Should be there by 10:00.”
- For a formal meeting (email): “I apologize for the delay. I am currently stuck in transit and expect to join the call by 10:30.”
- For a casual team (in person or group chat): “Sorry, running late. ETA 9:20.”
Understanding Tone and Context
The way you say “I will be late” changes based on who you are talking to and how you are communicating. In a professional email, you need a complete sentence and a polite apology. In a workplace chat, shorter phrases are acceptable. In a formal setting, you should avoid casual language like “gonna” or “stuck.” The key is to be honest, specific, and respectful of other people’s time.
Formal vs. Informal Language
Formal language uses full sentences, polite apologies, and specific details. Informal language is shorter, uses contractions, and may skip the apology. For example, “I apologize for the inconvenience, but I am running behind schedule” is formal. “Sorry, running late” is informal. Choose based on your workplace culture and the person you are addressing.
Email vs. Conversation vs. Chat
In an email, you have space to explain and apologize. In a conversation, you can adjust your tone based on the listener’s reaction. In a chat, speed is important, so a short message is often best. For example, in a chat you might write “Running 10 late. Sorry.” In an email, you would write “I am writing to let you know that I will be approximately 10 minutes late to our meeting this morning. Please accept my apologies.”

Natural Examples
Here are real-life examples of how native speakers communicate lateness at work. Notice the differences in tone and detail.
Example 1: Email to a Manager
Subject: Running late this morning
Body: “Dear Sarah, I wanted to let you know that I am running about 20 minutes late this morning due to a family emergency. I will be at my desk by 9:50. I apologize for any disruption to the morning schedule. Best, Mark”
Example 2: Chat Message to a Colleague

Example 4: Formal Email for an External Meeting
Subject: Delay for our 2:00 PM meeting

Common Mistakes
English learners often make these errors when saying they are late. Avoid them to sound more professional.
Mistake 1: Giving Too Much Detail
Incorrect: “I am late because my cat was sick, then I could not find my keys, and then the bus was full.”
Correct: “I am running late due to an unexpected personal matter.”
Why: Your manager needs to know you are late and when you will arrive, not the full story. Keep it brief.
Mistake 2: Not Giving an ETA
Incorrect: “I will be late. Sorry.”
Correct: “I will be late. My ETA is 9:45.”
Why: Without an estimated time, your team cannot plan around your absence.
Mistake 3: Using the Wrong Tone
Incorrect (too casual for a boss): “Hey boss, gonna be late. See ya.”
Correct: “Hi John, I wanted to let you know I am running about 10 minutes late. I will be there as soon as I can.”
Why: Casual language can seem disrespectful in a professional hierarchy.
Mistake 4: Apologizing Too Much
Incorrect: “I am so, so sorry. I feel terrible. I know this is awful. Please forgive me.”
Correct: “I apologize for the delay. Thank you for your patience.”
Why: Over-apologizing can make you seem less confident. A simple, sincere apology is enough.

Frequently Asked Questions
1. Should I always apologize when I am late?
Yes, a brief apology is expected in most workplace cultures. It shows respect for the other person’s time. However, you do not need to apologize more than once. A simple “I apologize for the delay” is sufficient.
2. How much detail should I give about why I am late?
Give a brief, honest reason without oversharing. For example, “due to traffic” or “due to a personal matter” is enough. You do not need to explain every step of your morning. If the reason is private, simply say “due to an unexpected issue.”
3. Is it better to call or send a message when I am late?
It depends on the situation. For a one-on-one meeting with your boss, a phone call is more respectful. For a team meeting, a group chat message is fine. For a formal client meeting, an email is best. When in doubt, send a message immediately and follow up with a call if needed.
4. What if I am late very often?
If you are frequently late, the phrases themselves are not the problem. You need to address the root cause. Communicate with your manager about your schedule, and consider adjusting your routine. Frequent lateness can damage trust, so it is important to be proactive and honest about the situation.
