Calendar management has an image problem. It gets described as the entry-level part of the job, the thing you do until you are trusted with something better, and assistants sometimes apologize for how much of their week it takes.
I would put it the other way round. Your executive's time is the scarcest asset in the building, and you are the person who allocates it. There is a version of this work that is genuinely clerical – moving a meeting because somebody asked you to – and a version that decides what the company's most expensive hour gets spent on. The gap between them is the whole job.
I made this the subject of a chapter in the book, and the audiobook excerpt is episode 185 if you would rather hear it. What follows goes further than the chapter does, drawing on the conversations since.
The calendar is a statement of priorities, whether or not anyone meant it to be
Print a month of your executive's calendar and add up where the hours actually went. Almost nobody's answer matches what they would say their priorities are.
That gap is the most useful thing you will ever put in front of an executive, and it is not a confrontation – it is a document. Heleen Vink, management assistant to the deputy CEO of Ingka Group (IKEA), describes a calendar audit that reset priorities, and it is the clearest example I have of this working at scale.
Do it quarterly. Count the hours in each category – leadership team, customers, one-to-ones, recruiting, external speaking, internal admin – and show the split next to the stated goals for the quarter. You are not asking for a decision. You are handing over information that only you have.
Agree the rules once, so you are not renegotiating every week
Most calendar friction comes from decisions that were never made explicitly. The fix is a short conversation, repeated once or twice a year.
Work out with your executive:
- Default meeting lengths. If the default is 30 minutes and it should be 25, that recovers most of a day a month. Somebody has to decide it once.
- The buffers. Between back-to-backs, and around travel. A calendar with no gaps is a calendar that runs late by 11am.
- Protected blocks. What time is not available at all, and what would genuinely justify breaking it. "Nothing" is a valid answer and a useful one.
- The standing commitments. Which recurring meetings are permanent, and which get reviewed.
- Who gets same-week access. The board, the direct reports, the top customers – and who has to wait.
- What you decline without asking. This is the important one, and it is below.
Write it down. Not because either of you will forget, but because a written default is what lets you say no to a senior person without it being personal – you are applying an agreed rule rather than making a judgment about them.
The calls you make without asking are the job
Any assistant can move a meeting when told. The value is in the decisions you make on your own, and the range of those decisions is roughly the measure of seniority in this role.
Claudette Clayton, twenty-five years an executive assistant, talks about this alongside email management and delegation, and about how the boundary keeps moving as the job evolves.
The way to widen it is not to ask for more authority. It is to make the calls and then report them. "I moved the Thursday review to next week because the numbers will not be ready – tell me if you would rather I hadn't." Do that for a few months and the asking stops being necessary, because your executive has watched you make the same decision they would have made.
What you are building toward is being able to answer, without checking: is this meeting worth their time? Could someone else take it? Does it need to be this long? Should it be an email, a Loom, or nothing at all?
Protect the gaps, not just the slots
A full calendar looks productive and performs terribly. Thinking time, preparation time and recovery time do not put themselves on a calendar, and nobody complains when they are missing – which is exactly why they disappear.
My own CEO and I have talked about this on the show, in a conversation about automation, energy management and how our partnership works. The framing I have found most useful is energy rather than time: two hours after a board meeting are not the same two hours as first thing on a Tuesday, and a calendar that treats them as interchangeable is quietly setting your executive up to do their worst work at the moment it matters most.
So look at the shape of a week, not just its density. Hard thinking in their best hours. Low-stakes meetings in the trough. Nothing important immediately after something draining. I wrote about the mechanics of this years ago in how to manage your calendar before it manages you, and the principle has not changed.
Automate the scheduling that has no judgment in it
Some scheduling is a decision. Most of it is a negotiation about availability, which is a problem software solves better than either of us.
Booking links for the meetings you would have accepted anyway, reminders that cut no-shows, and a standing intake for the requests that arrive constantly. I've written up the case for this in how executive assistants can automate meeting scheduling, and episode 241 walks through the tool I use – YouCanBookMe, which is made by Capacity, where I work, so take the recommendation with that in mind.
The test for whether something should be automated is simple: if you would say yes to every request of this kind, stop being the middleman. If you would say no to some of them, stay in the loop.
Episode 20 is three tips for scheduling meetings from before any of the current tools existed, and the tactics in it still hold, because they are about the sequence you do things in rather than the software you do them with.
The systems that make this survivable at scale
Two habits come up again and again from assistants supporting more than one person, or supporting someone whose calendar is genuinely relentless.
A weekly look-ahead with your executive. Fifteen minutes on the week after next, not the week coming. By the time a week starts it is too late to fix it; two weeks out, everything is still moveable. I have argued this is the most important meeting of your week.
A written record of the reasoning. Not the events – the decisions. Why that meeting is permanent, why that person gets same-week access, why that block is protected. It is what lets you hand the calendar over for two weeks without the whole thing unravelling, and it is the difference between a calendar you run and one that only works while you are watching it.
The teams doing this at real scale are worth studying: the executive support office at Microsoft Germany talks through how a CEO office runs when more than one person shares the load.
When the executive is the problem
Sometimes the calendar is a mess because the person in it keeps making it one – saying yes in hallways, accepting invitations directly, treating protected time as negotiable the moment anyone pushes.
Three things help, in this order.
Show, don't argue. The quarterly audit does more than any conversation about boundaries. Numbers about their own time are hard to dismiss.
Make declining easier than accepting. Draft the no. Give them the sentence, the alternative, and the person who should take it instead. Most executives who overcommit are not undisciplined; they just find saying no expensive, and you can make it cheap.
Be specific about the cost. Not "your calendar is too full" but "you have four hours of prep time this week for a board meeting that needs eight." The first is a complaint. The second is a decision they can make.
If none of it works, that is worth knowing too. An executive who will not let their calendar be managed is telling you something about how this partnership is going to go, and it is better to learn it early.
And your own calendar
The thing almost every assistant does last, if at all.
Block your own focus time and defend it the way you defend theirs. Put your lunch on the calendar. Take the holiday. An assistant running on empty makes worse calls about everybody else's time, and the judgment is the part of this job that cannot be automated or delegated.
The episodes below cover all of it – the chapter, the tactics, the tooling, and the assistants who have been doing this longest.
