How to Handle Interruptions at Work Without Being Rude

A coworker leans in with "Got a sec?" just as the hard part of your report finally makes sense. You don't want to snap at them, and you don't want to lose the thread either. Those two goals rarely conflict. A polite deferral takes one sentence, and a small habit before you look up makes it much easier to pick up where you left off.

What an interruption really costs

It helps to know what you are protecting, because the cost is not always the one people expect.

Short interruptions cause mistakes. In a set of experiments published in the Journal of Experimental Psychology: General, interruptions averaging 4.4 seconds tripled the rate of sequence errors on a task that required people to keep their place in a series of steps, and interruptions averaging 2.8 seconds doubled it (Altmann, Trafton & Hambrick, 2014). That was a lab task, not an office, but the lesson carries over: even a "quick question" can make you lose your place.

The effect on quality depends on the work. In a lab study of an email-answering task, researchers at the University of California, Irvine and Humboldt University found that interrupted people actually finished in less time, with no difference in quality. They seemed to compensate by working faster. The price showed up elsewhere: after only 20 minutes of interrupted work, participants reported significantly higher stress, frustration, workload, effort and pressure (Mark, Gudith & Klocke, 2008). A different experiment, in which 54 students wrote essays, found that quality of work was significantly reduced when the writers were interrupted (Foroughi et al., 2014).

Put together, a fair reading is this: on routine work you can often absorb interruptions by speeding up, though it wears on you, while complex, creative work is more likely to suffer. These are controlled studies with specific tasks, so treat them as a guide rather than a forecast for your own day.

The ten-second bookmark

Here is the habit that does the most good for the least effort. When someone appears at your desk or a message pops up, don't answer right away. Say "one second," and use that second to leave yourself a trail.

Finish the sentence, line or cell you are on, if you can.
Write the next step in plain words: "Next: check Q3 totals against the invoice list."
Leave your cursor, or a highlight, exactly where you stopped.

There is research behind this pause. In experiments with simple problem-solving tasks, having a chance to prepare before the break reduced the time cost of resuming afterward (Hodgetts & Jones, 2006). The moment between "something wants my attention" and "I'm now dealing with it" is short, and you get to decide how to spend it.

Asking for that moment is not rude. "One second, let me finish this thought so I can give you my full attention" tells the other person they are about to be listened to properly.

How to say "not now" kindly

Most people who interrupt don't need an answer this minute. They need to know their question has landed and will be dealt with. A good deferral has three parts:

Acknowledge. Show you heard them and that the request matters.
Offer a time. A specific one. "Later" sounds like a brush-off; "at 2:30" sounds like a plan.
Follow through. Go to them at the time you named. This is what earns you the right to defer next time.

Some wording you can borrow and adjust:

Situation	What you might say
A coworker stops by your desk	"I want to give this real attention. I'm mid-task until 11. Can I come find you then?"
A chat message while you're focused	"Saw this. Heads down until 3, and I'll reply right after."
Your manager adds a new request	"Happy to. I'm working on the client deck right now. Should this come first, or is end of day OK?"
Someone who drops by often	"Could we save these up and go through them together at 4? I'll give you better answers that way."
A quick question you can answer in a breath	Answer it, then go back to your note.

A few things keep these from sounding cold. Use a warm tone and, in person, look up from the screen while you say it. Give a short reason without a long apology. And with your manager, ask about priority instead of refusing: they may know something that makes the new request more urgent than what you're doing, and deciding that is part of their job.

Getting back on track afterward

The conversation is over, and now your brain wants to check email "just for a minute." This is the point where a five-minute interruption turns into a lost half hour. A short re-entry routine helps:

If the interruption created a new task, write it on your list so it stops circling in your head.
Close whatever you opened to help the other person.
Reread your bookmark note and the last few lines you wrote.
Do the smallest next action, even if it takes two minutes.
If your focus still feels scattered, set a short timer and commit to that one stretch.

That last step is where a tool can help. The focus timer gives you a fixed window to settle back in, and if you are unsure how long that window should be, the guide to choosing focus session lengths walks through the options.

If you forgot to leave a note, don't try to remember where you were. Reconstruct it: scroll up, reread the last paragraph or the last few changes, and ask yourself what you were about to do. It is slower than a bookmark, but it beats staring at the screen.

Making interruptions less frequent

Knowing how to handle interruptions at work in the moment is half of it. The other half is giving people an easy alternative to the tap on the shoulder.

Tell people when you are available. A status line such as "Focusing until 11, free after" answers the question before it gets asked.
Offer a regular slot. If the same few people need you often, a standing 15-minute check-in can replace a dozen drop-ins.
Pick one visible signal your team understands, like headphones on or a calendar block, and respect other people's signals in return.
Plan for the interruptions you can't prevent. A schedule with buffers survives a surprise far better than one packed to the minute; the approach in time blocking for interrupted days is built around that idea.

None of this will make your day interruption-free, and in many jobs it shouldn't. Helping colleagues is part of the work. The aim is simply to choose when you switch, most of the time.

Frequently asked questions

Is it rude to ask a coworker to come back later?

Not when you acknowledge the request, name a specific time and then keep your word. What comes across as rude is a vague "I'm busy" with no follow-up, or a sigh before you answer.

What if my boss is the one interrupting me?

Assume the request matters and ask where it ranks: "Should I pause the report for this, or finish that first?" You stay cooperative, your manager makes the call, and you avoid silently dropping work they also care about.

How do I stop interrupting myself?

Use the same bookmark trick on your own impulses. When a stray thought shows up ("I should email Dana"), write it on a side list and keep going. Review the list at your next break, when acting on it won't cost you your place.
