Notice the pattern before addressing the person
A coworker stopping by with a quick question may not seem like a problem on its own. Repeated interruptions are different: you have to pause, understand the request, answer it, and find your place again. If this keeps happening during work that needs sustained attention, it is reasonable to look for a better arrangement. You do not need to prove that every interruption is unnecessary before you ask for fewer of them.
Start by noticing when interruptions happen and what people need. Are they waiting for a decision only you can make? Do they lack access to a document? Are several people asking similar questions? This is not about keeping a score against a coworker. It helps you choose a response that fits the problem: a brief answer, a shared resource, a regular check-in, or a clearer way to flag urgent work.
Respond in the moment with a time and a next step
When someone interrupts you, a short response is often more useful than a long explanation. Try: “I’m in the middle of something that needs my attention. Can you send me the question, and I’ll look at it at two?” This acknowledges the person, states your limit, and gives them a next step. If the question is genuinely quick and you have room to answer, you can choose to do so. The important part is making that a choice rather than an automatic response to every interruption.
Some requests cannot wait. You might ask, “Is this blocking something that has to happen before two?” If it is, find out what decision or information is needed and respond to that part first. If it is not, return to your planned follow-up time. You can be courteous without leaving “later” undefined, especially when a coworker depends on your answer to continue their own work.
You may need to repeat the same boundary a few times. Keep your wording steady rather than adding a new justification each time: “I can’t switch tasks right now. Please put it in a message, and I’ll reply after this work block.” A calm, consistent response makes your availability easier to understand.
Make focused time visible and predictable
A boundary is easier for others to respect when they know when you are available. If your workplace allows it, place a focus block on your calendar, update your chat status, or use a brief note such as “Working on the report until 11; checking messages afterward.” These signals will not stop every interruption, but they reduce guesswork. Make sure the times you offer for replies are realistic, and follow through when you can.
It also helps to name the appropriate channel for different kinds of requests. For example, a message may suit a non-urgent question, while an agreed direct call may be appropriate for a time-sensitive issue. The useful distinction is not “never interrupt me.” It is “here is how to reach me when something can wait, and here is what to do when it cannot.”
Have a separate conversation if it keeps happening
If the same coworker continues to interrupt your focus blocks, raise it outside the rushed moment. Describe the effect on the work, not their personality: “I’ve had trouble finishing the draft when I stop to answer questions throughout the morning. Could we collect non-urgent questions and go through them after lunch?” Ask whether that timing works for them. They may have a deadline or dependency you did not know about, and the best arrangement should account for both workloads.
Sometimes interruptions point to a team process that needs attention. If several people need the same answers, a shared document or short recurring check-in may help. If requests are repeatedly labeled urgent, the team may need to agree on what urgent means and who can make decisions when you are unavailable. When you cannot change those expectations yourself, bring the specific workflow problem to your manager: explain what you are trying to complete, what is interrupting it, and what agreement would help.
Keep the boundary workable
Protecting focus does not require being unreachable all day. Try a modest change, such as one uninterrupted hour followed by a scheduled window for questions, and see whether it supports the work. If your role involves frequent immediate support, a shorter focus block or a teammate covering requests may be more practical than a blanket rule.
A useful boundary tells coworkers what they can expect from you while giving you a fair chance to finish demanding tasks. When you pair a clear limit with a reliable way to follow up, you can reduce repeated interruptions without treating every question as a conflict.
