Microsoft has been counting
Microsoft's June 2025 Work Trend Index special report — Breaking down the infinite workday — pulled together a year of telemetry across the M365 estate and turned it into a set of numbers that are hard to forget once you've seen them. A few of the headlines:
- The average knowledge worker is interrupted every two minutes during core hours, totalling around 275 interruptions a day from meetings, emails and chats.
- 153 Teams messages received per weekday, on average. 117 emails per day, most skimmed in under sixty seconds.
- Meetings starting after 8pm are up 16% year on year.
- 30% of meetings now span multiple time zones — eight percentage points higher than 2021.
- 48% of employees and 52% of leaders describe their work as "chaotic and fragmented."
- 80% of global workers say they don't have enough time and energy to do their work.
Read those quickly and you might react the way many leadership teams have: another wellbeing memo, another commitment to "meeting-free Fridays" that lasts six weeks. That's not the response the data is asking for. The infinite workday isn't a culture problem you can solve with a poster. It's a structural one — and a fair amount of the structure is now being reshaped by AI features most users haven't been shown.
The real lever: meeting load
Sixty percent of all meetings are now ad-hoc, and one in ten is scheduled at the last minute. Half of all meetings happen in the windows 9–11am and 1–3pm — exactly the cognitive peaks people would otherwise use for deep work. The system is eating its own young.
Three M365 features, in combination, change that arithmetic in a way teams underestimate.
Intelligent Recap (Teams Premium or with a Microsoft 365 Copilot licence) makes it genuinely safe to skip a meeting. AI-generated notes, recommended tasks, speaker timeline markers, chapters — you can catch up on a 60-minute call in four. The meeting culture shift is subtle: if I trust the recap, I stop attending meetings I don't need to be in. That's not laziness; that's the right behavioural response to a tool that finally works.
Facilitator (with a Microsoft 365 Copilot licence) sits in the meeting and takes notes in real time directly inside the meeting chat. Decisions and questions are captured live; tasks are pulled out as they're discussed. The killer effect isn't the recap — it's that the meeting itself is shorter because the facilitator is doing the secretarial work nobody volunteered for.
Copilot in the chat panel during a Teams meeting can now answer summarise the call up to this point mid-meeting. Anyone joining late doesn't pull six other people back to where they were ten minutes ago.
Together, those three features deliberately remove the social cost of skipping a meeting. That's the real story.
The other lever: the messages
153 Teams messages a day is more than one every three minutes during a typical eight-hour day. The good news: most of those messages are not actually about you. The bad news: there's no built-in way to tell, and most users still treat every notification as deserving of attention.
Two small interventions help disproportionately.
First, train users on Copilot Chat in the side panel — specifically, the prompt what's happened in my mentions and DMs since 2pm yesterday and what genuinely needs me. It's a five-second prompt and it cuts triage time by something like 70% based on the cohorts I've trained.
Second, get senior leaders to model scheduled send and delayed delivery. The reason late-night chats are up 16% year on year is not because people want to be working at 10pm. It's because senior people are catching up at 10pm and don't realise their quick thought, no rush note creates anxiety down the line. Scheduled send to 8am the next morning fixes that without anyone needing a wellbeing slogan.
What this means for your training programme
If you run Copilot or Teams training and you're not anchoring sessions on the infinite-workday data, you're missing the most persuasive case for the tool you have. Save 9 hours a month — Forrester's 2025 figure — sounds nice. Get out of half the meetings you didn't need to be in, and triage 153 messages in five minutes lands harder.
Anchor your training on the pain. The features sell themselves once you do.
