Passive-aggressive comments, unclear feedback, and low emotional intelligence are obvious red flags in professional communication.

But there is another red flag that often flies under the radar (= goes unnoticed), even though it is more common than it seems.

A red flag is a warning sign. Basically, it’s anything that makes you go “Wait, something is off here (= something is wrong).

In this article, we’re looking at a very specific kind of red flag: the phrases people use when they want to avoid responsibility, delay a decision, or politely get rid of you.

Here are 10 common phrases that sound clear and professional at first, but can become red flags when you hear them again and again.

────────────

1. I’m not sure

In polite communication, “I’m not sure” is a common replacement for “I don’t know.”

For example:

“I’m not sure about that. I’ll check with the team.”

It’s not a red flag on its own. People are allowed to be unsure. In fact, it’s often better to say “I’m not sure” than to pretend you know the answer.

However, when you hear this phrase again and again, it can mean a few different things:

“I don’t want to take ownership of this.”
“I’m trying to politely reject this idea.”
“I don’t want to move forward.”

In other words, “I’m not sure” can express a clear lack of interest and a desire to end the conversation.

2. Let’s see

You may also hear its variation:

“Let’s see what happens.”

This phrase is the enemy of clear next steps.

It can often mean:

“Let’s just forget about this for now.”

Again, it’s not always a bad phrase. Sometimes people really do need more time. But if “Let’s see” becomes the only answer you get, the conversation is probably not moving anywhere.

Tip: If you need to end a conversation with a clear next step, do not take “Let’s see” as the final answer.

You don’t have to be pushy, but you can try to get a more specific answer.

For example:

Your client: “I’m not sure about that yet. Let’s see what happens.”
You: “Of course. Just so I know how to plan on my side, when would be a good time to check back in?”

────────────

3. We’ll get back to you

What often follows this phrase is a long silence where you’re left wondering if the conversation is still alive.

The red flag is when there is no timeline and no follow-up.

The best way to handle this is to set the pace of the conversation yourself.

For example:

“Sounds good. When would be a good time for me to follow up?”

Or:

“Great, I’ll check in with you next Tuesday if I don’t hear back before then.”

────────────

4. I’ll keep this in mind

People tend to say this when they really want to say:

“I’m going to ignore everything you just said”

What may help in this situation is to outline one or two key action steps and explain why they’re important.

For example:

Your teammate: “Alright. I’ll keep this in mind.”
You: “Thanks. Just to make this easier to act on, I’d start with the first two test cases. Those are the ones most likely to block the release.”

────────────

5. That’s interesting

This phrase is a polite conversation, especially in small talk.

Note: The tone and context really matter here. If it’s said in a flat tone and not followed by anything else, it definitely signals a lack of interest.

Compare:

“I’ve decided to push back my vacation to Dubai.”
“Really? That’s interesting. Why, though?”

And

“I’m planning a business trip next month.”
“That’s interesting”

So, just keep in mind that this phrase only works when someone shows genuine (= real) interest.

────────────

6. Maybe later

“Later” is one of the most dangerous words in professional communication.

Remember me for faster sign in

What it often means is:

“Not now, and possibly never.”

The problem with “later” is that it sounds hopeful, but it doesn’t give you anything concrete.

Instead of accepting “later,” clarify a specific timeline so you can put the project, idea, or request into a clear yes or no pile instead of following vague promises.

For example:

“Sure. When would be a better time to discuss this?”

Or:

“Totally. Should I follow up next week, or is this not a priority right now?”

────────────

7. We’re still discussing it internally

You may also hear:

“We’re still discussing it with the team.”

At first, this sounds reasonable. You may think the decision is just taking time.

But in reality, time is probably not the real issue.

When you keep hearing this phrase, it often means people are hesitating to move forward because the value, urgency, or next step is not clear enough.

In other words, the conversation is stuck.

The longer you wait, the less likely you are to get a positive answer. So instead of just giving people more time, give them a more compelling reason to move forward.

For example:

“Of course. Is there any specific concern the team is discussing? I’d be happy to clarify anything that would help with the decision.”

────────────

8. I’ll need to look into it

To look into something means to investigate it or do more research before making a decision.

In most communication contexts, this phrase is completely fine.

For example:

“I’ll need to look into the issue before I can give you a clear answer.”

The problem is that sometimes, “I’ll need to look into it” is used as a polite way to postpone a decision.

What it really means in this case is:

“I don’t want to make that decision, so I’ll just say I need more time or information.”

The person doesn’t actually look into it. And your follow-ups don’t help because there was never a real plan.

The solution is to clarify the next step immediately.

For example:

“Of course. What information do you need to look into?”

Or:

“Got it. When do you think you’ll have enough information to decide?”

────────────

9. I hear you

“I hear you” is a common active listening phrase. It shows that the person understands your opinion or concern.

That can be a good response.

The red flag is that “I hear you” can also be used to dismiss what you say.

It can sound like:

“I understand your concerns, but I’m not going to do anything about them.”

This is especially frustrating because the phrase sounds empathetic on the surface.

One solution here is to move the conversation away from acknowledging feelings and toward action.

For example, you may say:

“Thanks for understanding my perspective. My main concern is that we may not have enough time to test this properly before the release. That’s why I’m suggesting we move the deadline by two days or reduce the scope.”

────────────

10. Let’s circle back to that

This is one of the most commonly used phrases in business communication. And that is exactly the problem.

It is so overused that it has almost lost its meaning.

Instead of meaning “Let’s return to this conversation later,” it often means:

“Let’s move this topic out of the conversation and forget about it.”

Again, the phrase itself is not bad. Sometimes you really do need to circle back because the topic is not relevant right now.

But if there is no specific time, meeting, owner, or next step, “Let’s circle back” becomes another way to avoid the issue.
