Extra work often arrives as a small request with a hidden cost: switching tasks, gathering information or taking ownership of a continuing responsibility. Before answering, identify what the request actually involves. A quick review and responsibility for the whole project are not the same commitment.
You can be helpful without making an open-ended promise. State the part you can offer, the time available and what remains with the original owner. If the answer is no, a concise explanation and a relevant next step can keep the exchange clear.
What you know
You can identify your existing commitments and the specific part of the request you understand. You can estimate the time you have available.
What you don’t know
You may not know whether the request is optional, who owns the task or which existing priority can change. Clarify these before committing.
Read the situation before guessing the tone.
A boundary works best when its scope is visible. “I can review one page” leaves less room for misunderstanding than “I can help a bit.” Explain what you will and will not take responsibility for.
If a small favour becomes a recurring task, discuss ownership explicitly. The issue may be a missing process rather than a single colleague asking too much. Keep the conversation about the work and the effect on your existing responsibilities.
Three ways the conversation could unfold.
Constructed examples. Change the facts, dates and commitments to match your situation.
01 / Your manager
Your manager
A new task would displace work already agreed for the week.
Their messageCould you pick this up as well?
A possible replyI can take it on if we move the analysis to next week. Otherwise I won’t have capacity. Which would you prefer?
Make the trade-off visible before accepting the new task. Ask for confirmation when another team depends on the original deadline.
02 / A colleague
A colleague
You can offer a short review but cannot own the work.
Their messageCan you help with this presentation?
A possible replyI can review the opening slides for 15 minutes tomorrow. I can’t rewrite the full deck or take over the presentation.
The offer is useful and bounded. Check that the colleague wants that limited help before spending time on the wrong part.
03 / A client
A client
An additional request needs a new estimate.
Their messageCould you include one more set of changes?
A possible replyThat is outside the agreed work. I can confirm an estimate and schedule before we start, or we can keep the current delivery unchanged.
Separate willingness to discuss the addition from permission to begin it. Verify the scope before asserting that something is additional.
Choose one useful next step.
Ask what “help” means
Clarify the output and owner. Do not accept a vague role and discover later that everyone expected you to finish the whole task.
State your limit once
Give a concrete boundary and avoid weakening it with several contradictory offers. You can still listen if new information changes the situation.
Review recurring requests
If extra work repeatedly consumes the same time, discuss allocation and priorities with the appropriate person.
The most useful response is the one other people can plan around. A smaller honest offer or an early no is often more workable than an unclear yes. If your workload is repeatedly unmanageable, keep factual examples and seek an appropriate workload discussion.
