One number from Microsoft’s June report spread fast: 275. That is how many times, on average, a worker gets interrupted in a day by a meeting, an email, or a chat notification. Spread across normal work hours, that works out to an interruption roughly every two minutes. The figure came from Microsoft’s WorkLab, which published a report called “Breaking down the infinite workday” on 17 June 2025. It is a striking headline, and one worth handling carefully.

275 times — what the number actually counts

The two figures in the headline measure different windows. Microsoft’s methodology note the “every two minutes” gap covers an eight-hour workday, while the 275 total is counted across the full 24 hours. Both figures also draw only on the top 20 percent of users by ping volume.

The finding isn’t wrong, but it applies to a narrower slice of workers than the headline suggests, in a specific eight-hour window. The data comes from Microsoft 365 usage signals and a survey of 31,000 workers across 31 markets. It counts pings inside one company’s software. Whether a notification at your elbow is a real interruption, or just noise you have learned to ignore, is not something usage data can tell you. The count is precise even if its meaning for any one person’s day isn’t.

The workday that never quite ends

The more telling part of the report is not the interruption count but the clock. Microsoft found that meetings starting after 8 p.m. rose 16 percent year over year, which the company attributes partly to teams spread across time zones. Chats sent outside the nine-to-five climbed 15 percent. And the evening does not close the loop: 29 percent of active workers were back in their inboxes by 10 p.m.

Alexia Cambon, a senior research director on Microsoft’s Copilot and Future of Work team, described the problem less as overwork than as constant fragmentation. “It’s not just that the work never ends—it’s that work is increasingly disruptive, leaving little time for moments of mental rest or focus,” she said. Many workers, she adds, feel harried and last-minute. That read comes from a Microsoft executive whose team also sells the AI tools pitched as the fix, which is context worth keeping.

Why the blur matters more than the count

The real cost of an interruption is rarely the seconds it takes to read a message. Independent research suggests the damage is what lingers. Sophie Leroy, dean of the University of Washington Bothell School of Business, coined the term “attention residue” for what happens “when part of our attention is focused on another task instead of being fully devoted to the current task that needs to be performed.” As she puts it, “attention residue easily occurs when we leave tasks unfinished, when we get interrupted”, or when we know we will have to rush the leftover work later.

Field research by Gloria Mark at the University of California, Irvine, has found that recovering from a single interruption can take almost half an hour. Her work also tracks how much shorter attention on screens has become, from about two and a half minutes on a single screen in the early 2000s to roughly 47 seconds in recent data. Set a half-hour recovery cost against a ping every two minutes and the arithmetic stops working. There may simply not be enough time between interruptions to recover from the last one.

Microsoft’s own data suggests people are spending prime hours coordinating rather than creating, with nearly half of employees describing their work as chaotic and fragmented. Motion is not the same as output.

What the report does and does not say

The source is worth keeping in view. This is one company’s reading of its own usage data, not an independent study of modern work. The data shows a pattern but doesn’t establish why it exists, or that the tools themselves are the cause.

The survey of 31,000 workers adds the human side that usage signals cannot: nearly half of employees and more than half of leaders describe their work as chaotic and fragmented. That matches the usage data, which supports the argument, but does not settle cause and effect. People who feel harried may ping more; or they may ping more and then feel harried. The report cannot separate the two.

Marc Holitscher’s, national technology officer at Microsoft Switzerland, proposed fix points where a vendor’s fix tends to point. The solution, he argues, “isn’t working hard but fundamentally reimagining how we work.” Microsoft’s version of reimagining runs through its AI products. That is a fair thing for a software company to propose, and a fair thing for a reader to weigh accordingly.

Which leaves the question the numbers raise but cannot answer. If the interruptions come from the tools, better tools might quiet them. If they come from an always-on culture that the tools simply make easy, no software redesign reaches the real decision, which is a human one about when the pinging is allowed to stop.
