Time blocking for managers - how to take back control of your working day

Do you ever feel like you have too much work to do?

There are the constant demands from your boss and colleagues, an overflowing inbox and a calendar full of meetings. You can end up feeling like a hamster on a treadmill. We run fast all day, only to collapse on the journey home, wondering, “Where on earth did that day go?”

You started with good intentions. You followed the advice of the productivity experts. You planned your day the night before and identified the three priority tasks on your to-do list.

Then you arrived at work. Your plan went straight out of the window as new requests, meetings and problems appeared. You responded to every demand, but your three important tasks remained undone. Take a house point for at least planning your day, and to paraphrase a well-known quote, all plans are great until they face the enemy.

I understand how you feel. I have been there too many times, and to get back on track, I wasted even more time looking for another productivity hack on YouTube.

During one of these despairing moments, I discovered time blocking. It was a revelation, although it was so obvious that I wish I'd known about it years ago.

What is time blocking?

At its simplest, time blocking means reserving specific times in your calendar for particular tasks or types of work. Your calendar stops being a list of meetings and becomes a plan for how you intend to use your working day.

For example, instead of just showing your meetings and video calls, your calendar could read:

• 09:00–10:00: Draft customer proposal

• 10:00–10:30: Respond to emails

• 10:30–12:00: Client meeting

• 12:00–12:30: Follow-up actions

• 13:30–14:30: Prepare monthly performance review

• 14:30–15:00: Buffer for unexpected work

Every block of time has a purpose with each task in its rightful place, and everything else waits its turn

Time blocking is sometimes confused with time boxing. The two methods overlap, but there is a useful distinction. Time blocking reserves space in your calendar for a task or category of work. Time boxing also gives the work a fixed time limit. When that time expires, you stop, assess your progress and decide what happens next.

Why time blocking works for busy managers

1. It reduces the number of decisions you make during the day

Without a plan, you must repeatedly decide what to work on next. Should you answer an email, prepare for tomorrow’s meeting, review a document or make progress on the project that has been sitting on your list for three weeks?

Time blocking moves some of those decisions to the beginning of the day or week, when you can make them more deliberately. When you open your calendar, you can see the priorities you have already chosen. You can spend less energy selecting the next task and more energy doing it.

In The 7 Habits of Highly Effective People, Stephen R. Covey said, "The key is not to prioritise what’s on your schedule, but to schedule your priorities.”

2. It protects time for focussed work

We often need long periods of time without interruptions to do focused, meaningful work. But if you don't block off that time, meetings will slip in.

Managers need time to think, write, analyse information and make decisions. Those activities are difficult to squeeze into the gaps between meetings.

Microsoft’s workplace research Breaking down the infinite workday found that employees using Microsoft 365 were interrupted by a meeting, email or notification on average every two minutes during core working hours. Interruptions are not merely inconvenient. Switching attention can increase your mental workload and make it harder to resume the original task.

If you do not protect time for the work that's important to you, other people will quite innocently fill your calendar for you. A time block acts like a nightclub bouncer protecting your most valuable working time.

3. It makes your workload visible

A to-do list can conceal an impossible workload. Ten tasks written on a page might appear manageable. Placing them into a calendar forces you to confront how long they may take and how much time you actually have available.

I am terrible at estimating how long some tasks will take. Time blocking can show you that the deadline you set or accepted is unrealistic. Over time, comparing your planned blocks with what actually happened should help you become a better estimator.

It can also support a more constructive conversation with your boss:“I can complete the customer proposal by Friday or bring forward the performance report, but there is not enough time to complete both to the required standard. Which should take priority?”

That is a stronger position than waiting until both deadlines have been missed.

4. It helps you respond to new requests

A fully blocked out calendar does not give you an automatic right to refuse every request. You need to remain responsive, and genuine emergencies do occur. However, time blocking makes the consequences of a new request visible.

If something new must go into your day, what will move out?

This is where the Work Survival SAFE Method can help:

• Situation: Understand what is being requested and how urgent it really is.

• Alternatives: Identify different ways to meet the underlying need.

• Firm Words: Explain clearly what you can and cannot do.

• Evidence: Refer to deadlines, priorities and existing commitments.

For example:“I’m completing the customer proposal for Friday. I can join the discussion at 3pm, or I can review the document and send comments before lunch. Which would be more useful?”

You have not simply said no. You have made your existing priority visible and offered workable alternatives. That is far safer than agreeing to everything, failing to deliver and accidentally discovering another novel way to resign.

5. It helps you notice overload

Time blocking is not a miracle cure. It can't fix an impossible workload, a dysfunctional organisation or a boss who treats every request as an emergency. It can, however, help you see if you are becoming overloaded before it gets to the burnout stage.

If priority work is repeatedly pushed into evenings and weekends, your calendar is showing you that something needs to change. It may be a planning problem. It may be a prioritisation problem. Or it may be that the volume of work exceeds the time and resources available.

Those are different problems, and each needs a different conversation.

How to start time blocking

You do not need to redesign your entire working life. Try this simple approach for one week.

1. Choose one important task

Start with a piece of work that requires concentration but is being constantly pushed out by meetings, emails or urgent requests. Resist the temptation to block every task on your list now.

2. Give it a realistic place in your calendar

Reserve 60 to 90 minutes and use a specific description such as “Draft customer proposal” rather than the vague “Focus time”. If colleagues can see your calendar, avoid including confidential details in the description.

3. Batch routine work

Create separate blocks for email, etc., rather than responding continuously throughout the day. This doesn't mean ignoring genuinely urgent messages. It means avoiding the habit of treating every notification as an excuse to stop what you are doing.

4. Leave room for the unexpected

Do not fill every minute. It is tempting, but resist. During your day you will have to deal with questions, problems and unforeseen events. Leave buffer time between important blocks or keep part of the day deliberately unallocated.

If your calendar has no flexibility, the first unexpected request will destroy the entire plan.

5. Protect breaks and transitions

A full day of back-to-back blocks is not a sign of impressive productivity. It is usually a plan that bears little resemblance to how the real world works. Allow time to take a break, make notes after meetings, prepare for the next conversation and occasionally think. I had one job where I had to time block lunch!

6. Review what actually happened

At the end of the day, compare your plan with reality. Ask yourself:

• Which blocks did I complete?

• What took longer than expected?

• What messed up my plan?

• Was the interruption genuinely urgent?

• What should I do differently tomorrow?

  
  

Is time blocking too rigid for the real world?

Time blocking does not mean controlling every minute of your life. In fact, the opposite can be true. When you know what needs your attention and when, you free yourself from worrying about everything else on your list.

Nor is a time block an unbreakable promise. If something genuinely more important appears, you can move the block. The important point is that moving it becomes a conscious decision. You can see what you are sacrificing and decide if it's a sacrifice you are willing to make.

Take back control of your calendar

Time blocking will not create more hours or remove every interruption. It will not solve an unreasonable workload by itself. What it can do is make your priorities visible, reveal what makes you miss working on them and give you better evidence for conversations about workload and deadlines.

Try it for one week.

Protect one important block each day, leave room for the unexpected and review what actually happened.

You may not gain more time, but you should gain more control over the time you already have.
