AI won’t cure ‘the infinite workday’ unless companies reengineer work, Microsoft says
Automating existing processes provides limited gains. Bigger leaps come from new workflows and organizational structures.

Hello and welcome to Eye on AI. In this edition…OpenAI wins a $200 million Pentagon contract…Salesforce finds AI models can’t use CRM software very well…and a new study shows how AI scrapers are overwhelming cultural institutions.
Back in April, Microsoft published some research about the modern workday, drawn from data it gathers anonymously about the use of its software applications. And honestly, the conclusions were kind of depressing. It found that we are all trapped in what the company is calling “the infinite workday.”
People start checking their emails before they even get out of bed. Then, when we are at work, the most productive hours of the day are filled with meetings and distractions. During core working hours, people are getting interrupted by messages or emails every two minutes on average—that’s 275 interruptions per day—Microsoft found. Nearly half of all meetings take place between 9 a.m. and 11 a.m. or between 1 p.m. and 3 p.m., which is exactly when neuroscientists say that most people’s brains are at their best for focused work and problem-solving. In fact, most people’s productive potential peaks at 11 a.m. but that’s exactly the most overloaded hour of the day, with chat traffic hitting its highest volume on average, as well as meetings and app usage spiking.
Things don’t get better in the evenings, either. For many employees, work peaks again after dinner. With teams working across time zones, the number of meetings taking place after 8 p.m. was up 16% year over year, according to Microsoft. Many people are still checking those emails as they crawl back into bed at 10 p.m.
This exhausting schedule has helped produce what Microsoft calls a “capacity gap”—53% of leaders say productivity must increase, but 80% of workers say they lack the time or energy to do their jobs.
So what’s AI got to do with this? Well, everyone is hoping that AI will save us from this perfect storm of impossible expectations meeting human limitations. But the technology itself won’t do this. In fact, a lot of the ways companies are deploying AI and people are using the technology could make things worse.
Forcing people to work faster, not better
Think about it. If you’re already drowning in meetings, emails, and constant interruptions, having AI help you write more emails and summarize more meetings isn’t really solving the problem—it’s just greasing the wheels of a dysfunctional system.
That was the main takeaway from my conversation last week with Jamie Teevan, Microsoft’s chief scientist and technical fellow, and Alexia Cambon, one of the lead researchers on Microsoft’s Work Trends Index.
“AI is delivering real productivity gains, but it’s not enough,” Teevan tells me. “The speed of business is still outpacing the way we work today.”
She says that crafting prompts for AI to perform tasks for us, such as conducting research or generating a business presentation, “actually increases our metacognitive burden.” In other words, to write a good prompt, a person has to think clearly about the steps they want the AI to perform, and provide a list of dos and don’ts. This thinking process necessitates concentration, and it also requires someone to transform things they know tacitly into explicit instructions. Having to do this, “can feel overwhelming,” Teevan says.
But there are better ways to work with AI that can alleviate this burden—or at least share it. AI itself can be used to help craft prompts, for instance, Teevan says. Cambon says that too many people are viewing AI as just another software tool. It’s better, she says, to think about it like a digital colleague—something to which you can assign entire tasks or processes.
More importantly, to get the most out of AI, companies need to change their organizational structures, the way their employees work, and also how they measure value. Microsoft has identified companies they call “Frontier Firms” that are doing this. At these organizations, 71% of workers say their company is thriving, compared to just 37% globally.
Now, it should be said, there are not too many of these Frontier Firms out there. Out of 31,000 companies Microsoft looked at, only 840 met the criteria. Most of these companies were in tech—many of them so-called “AI native” startups that have the benefit of being able to design their processes around AI from the start. “They don’t have to unlearn a whole load of stuff,” Cambon says. But interestingly, she says that some of the Frontier Firms were in professional services, like consulting, accounting, and law, which is an area where AI is rapidly disrupting traditional work processes and even challenging entire business models.
For non-AI native companies, getting the full benefits of AI means changing organizational management and structures. “It is about how do you externalize knowledge and make things available for AI to learn from,” Teevan says. “It is about creating feedback loops and being very intentional about the content we create for our teams.”
What ‘Frontier Firms’ are doing differently
Microsoft’s research suggests there are some key changes that differentiate the Frontier Firms from the rest. They prioritize impact over activity, focusing on the 20% of tasks that create 80% of a business’s value. They redesign workflows instead of just trying to automate them. (Rather than have AI write status reports, for instance, ask whether you need status reports in the first place.) And they increasingly use AI as agents that can handle entire workflows, not just individual tasks. In this world, employees become “agent bosses,” Microsoft says.
Cambon says that the Frontier Firms also tend to have much flatter organizational structures, where teams are organized around completing a specific project, not around areas of expertise. Does Microsoft have an interest in selling this narrative in order to convince companies to buy its AI software and cloud services? Sure it does. But that doesn’t mean it’s wrong. It is clear that the companies that get this right will have a big advantage. And the ones that don’t? They’ll just have increasingly efficient chaos and burnt out employees.
With that, here’s the rest of today’s AI news.

Introducing Fortune AIQ
AI is reshaping work. What does it mean for your team? Fortune has unveiled a new hub, Fortune AIQ, dedicated to navigating AI’s real-world impact. Fortune has interviewed and surveyed the companies at the front lines of the AI revolution. In the coming months, we’ll roll out playbooks based on their learnings to help you get the most out of AI—and turn AI into AIQ. The first AIQ playbook, The “people” aspect of AI, explores various aspects of how mastering the “human” element of an AI deployment is just as important as the technical details.- Companies are overhauling their hiring processes to screen candidates for AI skills—and attitudes.
