How to Say ‘I am not sure’ at Work
If you need to express uncertainty at work, saying “I am not sure” is clear but can sound hesitant or unprepared in professional settings. The best way to say it depends on whether you are in a meeting, writing an email, or speaking casually with a colleague. This guide gives you direct, professional alternatives that keep your tone confident while honestly acknowledging uncertainty.
Quick Answer: What to Say Instead of ‘I am not sure’
Use these ready alternatives in common workplace situations:
- In a meeting: “Let me look into that and get back to you.”
- In an email: “I need to verify that before I can confirm.”
- Casual conversation: “I’m not 100% on that.”
- When you have an opinion but no proof: “My understanding is that…”
- When you need time: “I’d like to double-check the details.”
Why ‘I am not sure’ Can Sound Weak at Work
The phrase “I am not sure” often stops a conversation. It does not tell your listener what you will do next. In a professional environment, colleagues and managers want to know if you will find the answer, if you need help, or if you are simply thinking. Replacing “I am not sure” with a phrase that shows your next step makes you sound more capable and reliable.
Formal vs. Casual Alternatives
Your choice of words should match the situation. Below is a comparison of formal and casual alternatives.
| Situation | Formal Alternative | Casual Alternative |
|---|---|---|
| Email to a client | “I will confirm this with the team and revert.” | “Let me check and get back to you.” |
| Meeting with boss | “I need to review the data before I can give a firm answer.” | “I’m not totally sure on that one.” |
| Chat with coworker | “I would like to verify that information.” | “I have no idea, actually.” |
| Presenting to a group | “That is not something I can confirm at this moment.” | “I’m drawing a blank on that.” |
Better Alternatives for Workplace Speaking
1. “Let me look into that and get back to you.”
When to use it: In meetings, during calls, or when someone asks a question you cannot answer immediately.
Why it works: It shows you are taking responsibility and will follow up. It is proactive, not passive.
2. “I need to verify that before I can confirm.”
When to use it: In emails or formal conversations where accuracy matters.
Why it works: It signals that you care about giving correct information, not just an answer.
3. “My understanding is that…”
When to use it: When you have a general idea but are not 100% certain.
Why it works: It frames your answer as your current knowledge, leaving room for correction without sounding unsure.
4. “I’d like to double-check the details.”
When to use it: Before making a decision or giving a final answer.
Why it works: It sounds careful and thorough, not uncertain.
5. “I’m not 100% on that.”
When to use it: Casual conversation with a trusted coworker.
Why it works: It is honest but not overly formal. It invites discussion.
Natural Examples
Here are real workplace scenarios showing how to use these alternatives.
Scenario 1: A manager asks about a project deadline during a stand-up meeting.
Instead of: “I am not sure if we can finish by Friday.”
Say: “Let me check the team’s progress and get back to you after the stand-up.”
Scenario 2: A client emails asking for a specific discount.
Instead of: “I am not sure if we can offer that.”
Say: “I need to verify our current pricing policy before I can confirm. I will revert by end of day.”
Scenario 3: A coworker asks if the report was sent to accounting.
Instead of: “I am not sure.”
Say: “My understanding is that it was sent yesterday, but let me double-check.”
Scenario 4: You are in a brainstorming session and someone asks your opinion on a new idea.
Instead of: “I am not sure if that will work.”
Say: “I’d like to think about that for a moment. Can we come back to it?”
Common Mistakes
English learners often make these errors when trying to avoid “I am not sure.”
Mistake 1: Using “maybe” too much.
Example: “Maybe I can do it.”
Problem: “Maybe” sounds weak and indecisive.
Better: “I can do it once I confirm the timeline.”
Mistake 2: Saying “I don’t know” in a formal email.
Example: “I don’t know the answer to your question.”
Problem: It stops the conversation and sounds unprepared.
Better: “I will find the answer and get back to you shortly.”
Mistake 3: Over-apologizing.
Example: “I’m sorry, I’m really not sure about this.”
Problem: It lowers your credibility.
Better: “Let me confirm that and follow up.”
Mistake 4: Using “I think” too often.
Example: “I think the meeting is at 3.”
Problem: It sounds uncertain even when you are fairly sure.
Better: “The meeting is scheduled for 3, but I will confirm.”

FAQ: Saying ‘I am not sure’ at Work
1. Is it ever okay to say “I am not sure” at work?
Yes, in very casual settings with close colleagues, it is fine. But in most professional situations, it is better to use a phrase that shows what you will do next. Even a simple “Let me check” is stronger than “I am not sure.”
2. What is the best phrase to use in a formal email?
“I need to verify that before I can confirm” or “I will revert once I have the details” are both professional and clear. They show you are handling the request.
3. How can I sound confident when I am actually unsure?
Focus on the action you will take, not the uncertainty. For example, “I will confirm that and get back to you” sounds confident because it focuses on the solution. Avoid filler words like “maybe” or “I guess.”
4. What if I am in a meeting and need time to think?
Say “I would like a moment to consider that” or “Let me think about that and come back to it.” This buys you time without sounding unsure. It shows you are thoughtful.
