Return to office mandates, calendar creep, and quarterly speed-ups have not produced a renaissance in motivation. Global employee engagement fell to 20% in 2025, the lowest since 2020, which Gallup estimates costs about 10 trillion dollars in lost productivity, roughly 9% of global GDP (Gallup, 2025). Managers are not immune. Their engagement dropped from 27% to 22% in a single year, the steepest fall since 2022, even as best-practice organizations report 79% of managers engaged (Gallup, 2025). The gap is not about grit. It is about design.
The cost of running hot
When almost four in five workers are not engaged, the default operating model is misfiring. The manager slump is the tell. If the people tasked with setting pace are themselves depleted, the system will push teams toward frantic sprints and firefighting, not sustainable performance. The contrast Gallup reports between typical and best-practice organizations suggests that engagement is a design variable, not a macroeconomic fate. The lesson for leaders is to fix the conditions of work, not just the messaging about resilience (Gallup, 2025).
Control, not heroics, predicts energy
A common worry about flatter structures is that removing hierarchy breeds chaos and stress. New multi-sample evidence cuts against that intuition. Morikawa, Martela and Hakanen developed and validated separate quantitative scales for organizational self-management and employee self-management, then tested them with employees from multiple organizations and a nationally representative Finnish sample of 2,000 people (Morikawa, Martela and Hakanen, 2025). Both forms of self-management were positively associated with work engagement and negatively associated with burnout. The relationships were partly mediated by job demands, consistent with the view that more control shifts how demands are experienced (Morikawa, Martela and Hakanen, 2025). This is correlational evidence, not causal, but it is notable that the data do not support the claim that less hierarchy inherently raises stress.
For executive teams, the practical read is simple. If you want energy to last, design autonomy into both the organization and the day-to-day job. Give teams real authority over how they schedule, prioritize, and improve their work. Use explicit standards for coordination rather than tacit approvals. The paper validates that organizational and individual self-management are distinct levers, so treat them that way in redesign efforts rather than assuming a one-size-fits-all autonomy program will do the job (Morikawa, Martela and Hakanen, 2025).
Time is a lever you can pull
Pace is not only cultural. It is calendrical. The largest six-country trial to date of a four-day workweek without pay cuts, covering 2,896 employees across 141 organizations, reported improvements in burnout, job satisfaction, and mental and physical health over six months (Fan, Schor, Kelly and Gu, 2025). Workers also reported feeling just as productive as before, despite working one day less, according to coverage of the study in Nature News (Nature News, 2025). The study identified mediating mechanisms that help explain the well-being gains, including improved self-reported work ability and reductions in sleep problems (Fan, Schor, Kelly and Gu, 2025).
Two design insights from this evidence matter. First, there was a dose–response pattern at the individual level. The larger a person’s own reduction in hours, the bigger the well-being improvement. That pattern did not simply scale with company-level reductions, which suggests leaders should manage time changes at the person and team level rather than by headline policy alone (Fan, Schor, Kelly and Gu, 2025). Second, the study is quasi-experimental. Participation was self-selected, the control group was not randomized, and most participating firms were small and in Anglophone countries, so we should not overclaim on causality or universal applicability. The authors acknowledge these limits, a point underlined by Nature’s reporting (Fan, Schor, Kelly and Gu, 2025; Nature News, 2025).
A smaller UK pilot points to the same direction of travel and the same caution. Seventeen organizations ran a six-month four-day week with no pay reduction, and all chose to continue afterward, but revenue and absenteeism data were limited, reported by few firms, and descriptive only. A public-policy scholar noted the likely self-selection of enthusiastic participants, which further tempers strong conclusions (CNN Business, 2025). The message is not that four days “works” everywhere. It is that systematic reductions in time can be paired with stable output, at least by self-report, and with clear gains in well-being in many settings.
How to redesign for a sustainable pace
Put the two strands of evidence together and you have a practical blueprint. Control and time are the currency of well-being. Autonomy without slack creates brittle heroics. Slack without control creates drift. Leaders need both.
Start with a pilot that combines team-level self-management with explicit time constraints. Give participating teams authority to redesign their workflows, then ask them to meet a fixed customer promise with fewer total hours. Require three safeguards that map to the evidence. First, define outcomes and quality standards clearly, since engagement rose with control in contexts where work demands were addressed, not ignored (Morikawa, Martela and Hakanen, 2025). Second, cut time where it is least value-adding: default 25-minute meetings, asynchronous status updates, and weekly “no internal meetings” blocks that protect deep work. Third, track what matters. Use a short weekly pulse on engagement, burnout, and sleep quality, paired with hard output and quality metrics. In the multi-country trial, perceived productivity did not fall when hours did, and well-being improved, so do not rely on presence as your proxy for performance (Fan, Schor, Kelly and Gu, 2025; Nature News, 2025).
Mind the manager load. Gallup’s data show managers are running on empty in many firms, which makes any change effort fragile (Gallup, 2025). Involve managers in setting the team’s pacing agreements, remove low-control administrative work from their plates, and make their own calendars a first-class design object. If you want sustainable pace across the system, start with the people who hold the calendar keys.
Finally, respect the caveats and learn in public. The best available studies here rely on self-reports and non-randomized comparisons. That should push you to treat each pilot as an experiment. Predefine the measures, publish the results internally, and iterate. The standard for progress is not a mythic productivity spike. It is stable or improved output alongside measurable improvements in engagement, burnout, and health. The global engagement slump is telling you that the current pace is unsustainable. The evidence gives you levers to change it.
