When the chief operating officer of a performance coaching firm conducted an informal social experiment1 to document how people responded to the question “How are you?”, they were surprised to discover that a majority of respondents—nearly 8 in 10—gave the same, one-word response:
Busy.
There’s little doubt that “busy” is an accurate description of what workers are currently feeling. A poll conducted by UCLA Anderson School of Management showed that nearly half of Americans feel “time poor”—like they have too much to do and not enough time to do it.2 And they’re feeling the squeeze in the workplace as well: Some 68% of respondents to another recent survey say they don’t have enough uninterrupted time to focus on important tasks during the workday.3
It’s not hard to understand why. Every wave of technological advancement has promised to make work more efficient. Economist John Maynard Keynes first predicted in 1930 that advanced technology would lead to a 15-hour workweek within a century.4 And yet the promise of a future where technology frees workers to focus on high-value work—strategic thinking, creativity, complex problem-solving—seems to keep getting deferred.
New tools meant to increase productivity and efficiency often add new layers of complexity instead: more notifications to check, more dashboards to update, more digital busywork. Workers are often left tackling tasks that feel urgent but not necessarily important.
If worker capacity is our most valuable resource, why do so many organizations struggle not only to find it—but to keep it?
Part of the problem may lie in the long-held belief that visible effort should be the primary measure of productivity, pressuring workers to always be “on.” A third of respondents to a survey conducted by software firm Visier say that they prioritize work that is most visible—regardless of whether that work is actually valuable to the business.5 And respondents to Deloitte’s 2025 Global Human Capital Trends survey (see “Methodology”) report that 41% of their time every day is spent on work that doesn’t contribute to the value their organization creates.
In the 2024 Global Human Capital Trends report, we explored the idea that traditional productivity metrics focused only on outputs may not capture the full picture of human performance and introduced a new equation that considers both business and human outcomes.
But shifting the way we measure productivity is only part of the solution. To truly realize both business and human outcomes, organizations will likely need to address a deeper issue that may be undermining performance. It’s the meeting overload, the outdated processes, and the myriad of nonessential work that drains focus and keeps people from achieving the outcomes that matter most.
This often comes with real costs for organizations: reduced performance; damage to employee morale and well-being; and erosion of organizational capacity, culture, and innovation. And as we move further into the era of generative artificial intelligence, getting stuck in nonessential work may also inhibit our ability to fully unleash the potential benefits of advancing technology, as advancements inevitably slow down when they reach humans who don’t have the capacity or bandwidth to learn, implement, or master the tools.
Our survey respondents say creating capacity for worker growth, imagination, and deeper thinking is a top priority. And yet they also say it’s one of the areas where they’re making the least progress among all the topics surveyed (figure 1).
As current efforts to rethink unnecessary work appear to be falling flat, how can leaders and workers come together to reclaim organizational capacity for enhancing human performance?
It’s about more than optimizing performance and resources for current work. It’s about reclaiming worker capacity for net new work, improved well-being, and better responsiveness to market changes and challenges. Opening up worker capacity hinges on an organization’s ability to implement two key things: a new corporate mindset about how we define and value slack—unscheduled, unassigned time that workers have autonomy over how to use—and a new mechanism to evaluate the best path to reducing or streamlining the tasks and processes that create unnecessary work.
Only 22% of our survey respondents say their organization is highly effective at simplifying work, however. To address the challenges created by an overload of unnecessary work, organizations can pause to take stock of work based with outcomes in mind, applying a work design framework focused on two dimensions: horizontal collaboration, which fosters cross-functional input, and vertical empowerment, which clarifies ownership and accountability across all levels.
Why are leaders and workers all so busy? What’s impeding organizations from making decisions, innovating, and improving both human and business performance outcomes?
It’s the complex decision-making that requires email chains 30 people deep. Old and outdated technology that needs constant, expensive maintenance to work properly, and doesn’t play well with newer, more advanced systems. It’s meeting overload, where people spend most of their day attending meetings about work rather than attending to the work itself. Even collaboration—which is generally considered a good thing—can be a distraction to achieving outcomes.6
Getting buried in nonessential work isn’t something that happens randomly; it accumulates over time as an organization becomes more complex. But to effectively address this deluge of unnecessary work in the interest of creating capacity, it’s important to first understand some of the current mindsets and mechanisms that create it.
Beyond understanding how noncritical work continues to accumulate, freeing up worker capacity will also require leaders to navigate tensions—in particular, between outputs and outcomes, and control and empowerment (figure 2). Leaders will need to make strategic decisions about how to balance these tensions as they strive to create slack for their workers.
Not all busywork is bad, of course. Sometimes rules and regulations can provide guardrails that protect against decisions that could have serious consequences. For example, highly regulated industries may have compliance requirements that seemingly create excessive administrative work but are designed to protect consumers or uphold ethical standards. And even the most mindful innovation and collaboration will create some transactional cost—after all, teams still need to communicate with colleagues on a regular basis; otherwise, a sense of camaraderie and connection may be lost and progress toward goals may be hindered.
Simply identifying and weeding out nonessential work is likely not enough to solve the issue on its own. The missing ingredient in the equation has been—and continues to be—the accompanying mindset shift around what should be done with the resulting freed-up worker capacity. In other words, how should workers be spending their time?
If the use of the word “slack” in this article gives you pause, you’re in good company. Many leaders equate it with “slacker”: someone who avoids anything that requires work or effort. But if we want a long-term solution to worker capacity, we need to reframe how we define—and value—slack.
Consider this analogy: In rock climbing, keeping slack in the rope that supports the climber is a critical practice that ensures the climber’s safety. It gives the climber the flexibility to move freely and prevents excessive wear and tear on the rope itself, which could lead to damage or failure in an unexpected event like a fall. And when something unexpected does happen—a foot slips or a rock breaks away—the slack in the rope allows it to stretch and absorb some of the force, reducing the impact on the climber.
Think about slack in the workplace in the same vein. Creating slack is not about giving workers opportunities to shirk responsibility, but rather giving them space to manage their responsibilities in ways that work for them and the business. Slack is the intentional creation of unscheduled, unassigned time in the workday that workers have complete autonomy over how best to use.
The real benefits of slack will likely emerge when leaders are able to let go of the belief that emerged during the Industrial Revolution that their job as leaders is to maximize worker utilization. Some organizations have had success over the past few decades in working to shift this mindset and recognize the value of slack in work design.
Google’s well known 80/20 policy, for example, famously encouraged Google employees to spend 80% of their time on core projects, and roughly 20% (or one day per week) on unplanned company-related innovation activities that interested them personally. Almost half of Google’s product launches, including Gmail, Google News, and AdSense, have been reported to originate from this extra “slack” in workers’ schedules.15
Likewise, at 3M, workers maxed their utilization at 85%, customizing the rest of their work time as long as they stayed within the strategic boundary of working on projects they felt had the greatest potential to create value for their organizations.16
Missing out on the value of slack could be a particularly risky mindset as gen AI and other advanced technologies are poised to take over many transactional tasks that can free up worker capacity. If we expect to fill every second created with more busywork—or even with more complex, critical work—we have fundamentally misunderstood the assignment. The assignment is to find the balance.
In particular, as AI takes over more tasks, workers will be increasingly asked to invest in work that requires critical thinking, innovation, collaboration, and meaningful human interaction. Creating space for those activities—and offering workers autonomy in managing them—improves engagement with work and reduces job-related burnout. Extra capacity also can be used to invest in individual development like skill building.
Consider Belgian company DPG Media as an example. DPG only schedules 80% of a team’s capacity with work. What do they do with the remaining 20%? Nothing. The buffer is meant to give workers the ability to accommodate any unexpected issues. If worker utilization was maximized at 100%, DPG says, unexpected work would lead to excessively long workdays and hours of overtime.17
But reclaiming worker capacity can’t be an exercise that benefits only the organization. When workers benefit, the organization also benefits. Improved worker well-being, for example, often leads to improved retention and business outcomes. In our 2025 survey, workers listed flexibility, well-being, time off, and learning new skills—all of which are facilitated when organizations create slack—among the top 10 motivations that drive them to perform at a high level. Reclaimed capacity can benefit both workers and organizations: One does not need to come at the expense of the other.
For example, health insurance company Medibank launched a four-day workweek experiment in 2023, using a 100:80:100 model: Workers received 100% of their pay, worked 80% of their hours, and were expected to maintain 100% of their productivity. The company worked to reduce low-value work to give the extra hours back to workers—calling the reclaimed time “the gift” and allowing workers to use the time any way they chose. Midpoint results of the experiment were promising: Productivity and performance levels remained the same, and worker turnover intention and absenteeism dropped dramatically while workers experienced a 9.6% reduction in job stress and a 13% improvement in overall health.18
Similarly, Salesforce’s cloud-based communications platform, aptly named Slack, recently invited employees to join a two-week experiment where they were instructed to take regular breaks from their work throughout the day and use that time however they wanted to. Over the course of two weeks, productivity scores increased by 21%; scores related to worker ability to manage stress increased a whopping 230%; worker focus increased by 92%; and overall satisfaction at work increased 63%. Even participants who didn’t take as many breaks still saw increased metrics.19
If creating slack can help workers and organizations reclaim capacity for investing in the outcomes that matter most, the practical question remains: Where do we begin? How can organizations find the slack that their workers need to perform at their best?
To start finding slack, organizations can think about challenging existing work processes by hitting pause and taking some time to evaluate their most important outcomes. This allows organizations to evaluate each task for a given role, project, or team and identify opportunities to reduce or automate certain activities, ideally leading to performance gains and more effective use of resources.
This kind of reset can be aided by implementing a framework for the reset that is both horizontal and vertical in nature. Horizontally, it’s about expanding reach—getting teams to collaborate across functions and borrow ideas from other areas. This kind of cross-pollination brings in fresh perspectives and helps break down silos. Taking a page from finance and learning from zero-based budgeting, for example, could help organizations reevaluate the tasks that are most important for achieving goals and outcomes.
Vertically, it’s about cocreating the redesign of work with workers at all levels of the organization. After all, who knows the work better than those who actually perform it? Engaging workers in the process of determining what work should be done and how it should be done can have a positive impact on employee engagement.
This horizontal and vertical framework and mindset that can help organizations ensure that they’re focused on the right work and the right outcomes, that they capture and “spend” the capacity created in the most impactful ways, and that they guard against unnecessary work creeping back into processes, losing the hard-won capacity gains.
An example of this process in action can be observed in the story of how Great Britain’s men’s eight rowing team course-corrected their mediocre competitive performance. After years of following the same processes, the same practices, and the same mindsets, they decided to streamline their efforts and focus on a single goal: making the boat go faster. As they prepared for competition, the team started evaluating every activity and addition to their practice routine with the question, “Will it make the boat go faster?” Any time the answer wasn’t “yes,” the activity was phased out. The result was a gold medal at the Sydney Olympics.20
This horizontal and vertical approach to reworking work is not the process reengineering of old; rather than top-down process redesign, it involves workers from the start. A work assessment is a prime opportunity for workers and leaders to collaborate on the task of addressing nonessential work. Often, the workers who are closest to day-to-day processes and how work actually gets done are in the best position to identify specific areas where this work is inhibiting performance. But only about a third of workers in our survey say they feel empowered to provide feedback about how to make their work more valuable (figure 3).
How can leaders and workers work together to identify noncritical work and create slack, and how can organizations build worker trust in the process?
Perhaps just as challenging as finding slack is resisting the tendency to want to fill the newfound capacity with more work. But doing so without careful consideration will only allow unnecessary work to creep back into the system, undoing any progress you’ve made in freeing up worker capacity. This is where leaders can play an important role as the drivers of organizational culture. Guarding reclaimed capacity means supporting from the top efforts to shift to a human performance culture that values outcomes over outputs. And it means being committed to continuous assessment and ongoing iteration.
The renowned early-20th-century management consultant Peter Drucker once said, “There is nothing quite so useless, as doing with great efficiency, something that should not be done at all.”26
This insight speaks to the heart of something many organizations may overlook: Efficiency doesn’t fully deliver if it’s applied to the wrong tasks. It’s easy to get stuck in outdated processes and practices. But what if we paused to assess what truly drives value? When organizations embrace slack, they’re not just clearing away noise; they’re creating room for fresh ideas, better performance, and healthier workers and work cultures. In the end, embracing slack isn’t just a strategy for reducing inefficiency. It’s a strategy for growth.
Because when organizations free their workers from busywork, they can create capacity to get busy with the right work.
Deloitte’s 2025 Global Human Capital Trends survey polled nearly 10,000 business and human resources leaders across many industries and sectors in 93 countries. In addition to the broad, global survey that provides the foundational data for the Global Human Capital Trends report, Deloitte supplemented its research this year with worker-, manager-, and executive-specific surveys to uncover where there may be gaps between leader and manager perception and worker realities. The survey data is complemented by more than 25 interviews with executives from some of today’s leading organizations. These insights helped shape the trends in this report.
