Tell your manager you have too much work by naming the commitments you cannot reasonably complete together. Bring a short list of deadlines, explain the conflict and recommend a change: move a date, reduce the scope or reassign a task.

You do not need a minute-by-minute defence of your working day. You need enough detail for someone to make a decision.

“I’m overwhelmed” describes how the work feels. It may be entirely accurate. Adding “the customer report and the revised proposal both need the same afternoon” gives the conversation somewhere useful to go.

Prepare a short workload list

Start with the work that is due soon or already at risk. For each item, note the deadline, what remains and who is waiting for it.

Keep estimates honest. If you think a report needs somewhere between three and five hours, say that. A precise-looking number will not help if you have not yet seen the source material.

Include the routine work that occupies your day: customer calls, scheduled meetings, approvals and support requests. A calendar with a two-hour gap does not offer an uninterrupted afternoon.

Separate out anything that is waiting for somebody else. “Waiting for the figures” and “checking the figures” require different decisions. Our 15-minute weekly review explains how to keep waiting items separate from work you can start.

Ask for a decision about specific deadlines

Request a short conversation while there is still time to adjust the plan. Name the conflict in the invitation:

Could we spend ten minutes reviewing this week’s deadlines? The customer report and proposal changes now overlap, and I need to agree which should move.

In the conversation, explain the position and offer a recommendation:

The report is due Thursday and the proposal changes are due Friday. With the customer calls already booked, I can complete one of those properly this week. I recommend keeping the report on Thursday and moving the proposal to Monday. Does that match your priorities?

This makes the trade-off visible without asking your manager to rebuild your entire task list.

If neither deadline can move, discuss what else can change. Could someone check the figures? Would a shorter first version meet the immediate need? Is another task safe to pause?

Use this email when you need to put it in writing

Subject: Decision needed on this week’s deadlines

Hi [name],

I need to flag a conflict between [task A], due [date], and [task B], due [date].

[Task A] still needs [remaining work]. [Task B] needs [remaining work]. Alongside [existing commitments], I don’t have enough time available to complete both by those dates.

I recommend [specific change], which would protect [important outcome].

Can you confirm whether to proceed with that plan, or identify which work should be reassigned or reduced? I need the decision by [time/date] to keep [commitment] on track.

Thanks,
[name]

Replace the brackets with real details and remove anything unnecessary. Avoid attaching a sprawling task register unless your manager needs it to make the decision.

When another “urgent” task arrives

Check its deadline before absorbing it into an already full day.

What time is this needed, and what depends on it? I’m currently finishing the report we agreed would come first.

If it does need immediate attention, make the effect explicit:

I can start this today. That means the report moves to Friday unless someone else takes over the final checks. Which arrangement should I use?

Sometimes the reply is simply, “They’re both priorities.” Bring the discussion back to the available time:

I understand that both matter. I can finish the report or the proposal by tomorrow, but I can’t commit to both. Which deadline has the more serious consequence if it moves?

A priority label does not settle a scheduling conflict. A decision does.

Confirm what changed

After the conversation, send a short recap:

Agreed: I’ll finish the report on Thursday. The proposal moves to Monday, and I’ll pause the website edits until it is complete.

Update the relevant task list or calendar too. If another person is affected, agree who will tell them about the revised date.

Without that follow-through, you can end up working to the new plan while everyone else still expects the old one.

If you work for yourself, use the same conversation with clients

The wording changes slightly when you are agreeing work with a client:

I can add the extra pages. To keep Friday’s delivery, we would need to remove the newsletter setup from this round. Otherwise, I can deliver the full scope on Tuesday.

Be clear about any fee changes separately. Do not leave the client guessing whether a revised date also means a revised price.

For your own projects, record the decision just as plainly: “Finish the customer work; move the website refresh to next month.”

One conversation can resolve a clash. If the same problem returns every week, bring that pattern to your next workload review. Ask which responsibilities should change on an ongoing basis, rather than repeatedly renegotiating the same overloaded Friday.
