Alternatives to “that's insane” at work
Why it can fall flat
“that's insane”
The phrase skips the specifics, such as why the deadline, decision or offer feels unrealistic, unfair or unacceptable. Because it is emotional and vague, it lands as an attack even when you only want the matter looked at again.
Say this instead
- 01
I'm struggling to see how this deadline is realistic. Can we go through what's involved and what could move?
Boss · Chat
Use it when a deadline or workload seems impossible, since it states your doubt clearly and invites a practical conversation.
- 02
I have serious concerns about this plan. I don't think it works as it stands, and I'd like to walk you through why before we commit.
Boss · Email
Choose this one when you strongly disagree with a decision and want to object in writing before it is locked in.
- 03
I really don't agree with that approach. It seems extreme to me. Can you walk me through your reasoning?
Coworker · Chat
Good for pushing back on a colleague's idea while keeping the focus on the reasoning, not the person.
- 04
Just saw the new schedule. It's a lot more than I expected and I can't see it working. Can we talk before the meeting?
Coworker · SMS
A quick heads-up like this suits a surprise you want to talk through before it becomes a bigger issue.
- 05
Thank you for the request. I can't agree to this timeline and scope as stated, as it goes well beyond what is realistic. I'd like to discuss what would work.
Client · Email
This lets you refuse an unreasonable demand firmly without insulting the client or agreeing to anything.
- 06
I was surprised by that decision and I don't think it's acceptable. Let's talk today about what happened and what needs to change.
Someone you manage · Chat
Fits a moment when a team member's choice crossed a line, because it is direct about the problem and moves to a conversation.
- 07
The salary range you shared is far below what I expected for this role, so I don't think it's a match. Is there any flexibility on it?
Recruiter / HR · Email
Reach for it when an offer is far off your expectations, as it is honest about the gap and leaves room for a reply.
Examples
Hi Bronwen, I've read the proposal to launch the new tool next Friday. I have serious concerns: the testing isn't finished, and I don't think that date is realistic. Could we meet tomorrow to go through it before we confirm anything with the client? Thanks, Ciaran
Honestly, I can't see how we hit that number by Friday. Can we look at what's driving it before we reply to the client?
What to avoid
- Don't use “insane”, “crazy” or “ridiculous” about a person's idea; describe the specific problem instead.
- Adding “no offense” or “with respect” before a blunt line signals that you know it's harsh.
- Sarcasm in writing is risky, because tone is easy to misread and hard to take back.
- If you can raise an objection privately first, do that rather than objecting only in front of a group.
