What to say when someone keeps missing deadlines

The first missed deadline is a bad week. The second is a coincidence. By the fourth you have a pattern and a problem, and by then you have also built up several weeks of silent frustration that is going to leak into whatever you finally say.

That is the trap. The longer you leave it, the bigger the conversation has to be, and the bigger it has to be, the longer you leave it. Meanwhile the person has had no signal that anything is wrong, because you have been quietly absorbing it.

So they get blindsided by a serious conversation about something they thought was fine. That is not their failure. That is a gap you created by waiting.

From the outside, every missed deadline looks the same. They are not, and the fix is completely different for each.

A clarity problem: they did not know what finished meant, or when it was actually needed, or that the date was firm rather than aspirational. Astonishingly common. "End of week" means Friday morning to you and Sunday night to them.

A capacity problem: they knew, they meant to, and three other people also gave them urgent work. You may not be able to see this at all, especially if some of that work comes from outside your team.

A performance problem: they knew, they had the time, and it still did not happen.

Start by assuming the first. Check the second. Only conclude the third when you have ruled out the other two — and most new managers conclude it far too early.

Have this one after the second miss, not the fifth. It should take four minutes and feel almost anticlimactic. That is the point.

Say what you saw, with no interpretation attached. Then stop talking and let them fill the silence. The silence is where you find out which of the three problems you actually have.

Do not open with "is everything okay?" — however kindly meant, it invites "yes, fine," and then you have to start again. Do not stack it onto the end of a one-to-one about something else, either. Give it its own two minutes so it is clear it matters.

The small version, after the second miss:

"The report was due Tuesday and it came Thursday. Same thing happened with the client summary a fortnight ago. What is going on?"

Then say nothing. Count to five in your head if you have to. The answer tells you which problem you have.

If it turns out to be clarity:

"That is on me — I was not clear that Tuesday was firm. Let's agree now: when I give you a date, I will say whether it is firm or a rough aim."

If it turns out to be capacity:

"Who else is giving you work? Let's write down everything on your plate and I will go and sort out the priority order, because that is my job, not yours."

If it is neither, and this is the third or fourth time:

"I have checked whether this is about unclear instructions or too much work, and I do not think it is either. So I need to be direct: this needs to change, and I want to understand what would make that possible."

When they commit to a new date:

"Good. And if it is going to slip again, I need to hear it from you before the date, not after. That part matters more to me than the slip."

Agree the check-in at the moment you hand the work over, not when it is already late.

"Let's look at this together on Wednesday" costs you ten seconds at handover and removes the entire problem of whether chasing counts as nagging. You are not chasing. You are turning up to a thing you both put in the diary.

It also moves the discovery of a problem from after the deadline to before it, which is the difference between a small adjustment and an apology to a client.

Do not quietly redo the work yourself. It feels like the responsible choice in the moment and it is the single most damaging thing on this list — it hides the problem from them, from your boss, and eventually from you.

Do not save it for the performance review. A review is the worst possible place for someone to hear something for the first time.

Do not send a passive version by message. "Just checking in on that report 🙂" is not a conversation, and everyone can tell what it means.

If you have had the clear conversation, ruled out clarity and capacity, agreed a specific change, and it is still happening — that is the point where this stops being purely a management conversation and starts involving your organisation's own process.

Talk to your HR team or your own manager before taking any formal step. Rules about warnings, documentation and timelines vary by company and by country, and getting the order wrong can make a fair decision unfair. This article cannot tell you what those rules are where you work, and you should not guess.

What you can do before then is make sure the record is honest: that you raised it early, that you said it plainly, and that they were never under the impression it was fine.
