There is a narrative that still circulates in boardrooms and LinkedIn profiles: that working more is working better, that suffering is a sign of commitment, and that those who complain about excess simply don't want to grow. This narrative is empirically false — and the organizations that still hold it are not being picky. They are being inefficient. The collapse of hustle culture is not a concession to fragility. It is the arrival, with some delay, of the data.
What the research says about overwork and productivity
The evidence on productivity and hours worked has been consistent for decades and continues to be ignored with astonishing regularity. A classic Stanford study, conducted by economist John Pencavel, showed that productivity per hour drops drastically after 50 hours a week, to the point that those who work 70 hours produce, in terms of real output, the same as those who work 55. In other words, overtime above a certain limit does not add up — they cancel out previous hours due to degradation of cognitive performance.
The cost of burnout is not just individual. The World Health Organization recognized burnout as an occupational phenomenon in 2019, and cost estimates for developed economies put the impact in the trillions of dollars in lost productivity, healthcare costs and turnover. A 2023 Gallup survey estimated that high-engagement workers are 23% more productive than average — and that engagement drops precipitously in chronic high-pressure environments. The paradox is that the environments that require the most long hours are often the ones with the lowest engagement.
In Brazil, data on sick leave due to mental disorders — today the second biggest cause of sick leave from the INSS, behind only musculoskeletal diseases — tell the same story. A culture of excess has a bill, and it appears on the company's balance sheet before appearing in the consciousness of those who generated it.
The wrong reading of quiet quitting
When the concept of "quiet quitting" went viral in 2022, the dominant reaction among leaders was disapproval: young people don't want to work, they are complacent, they lack ambition. This reading is a complete inversion of the phenomenon. Quiet quitting isn't doing less than the job requires — it's refusing to consistently do more than the job pays for, without recognition, growth, or meaning in return.
The distinction matters. A professional who fulfills his responsibilities well within the contracted hours and does not gratuitously and chronically extend his availability is not failing to commit. You are exercising a basic form of personal resource management. The problem is that many organizations have built their operations on the assumption that a portion of the team will regularly work overtime without asking for anything in return. When this assumption fails, the model breaks — not because people changed, but because the structure was poorly designed from the beginning.
What has changed with the generation that entered the job market in the last decade is not their willingness to work hard. It's the tolerance for working hard without clarity of purpose, without visible growth, and for leadership that confuses visible hours with value delivered.
What organizations that worship busyness are actually optimizing
There is a fundamental difference between being busy and being productive. Organizations that worship the appearance of intense work — long and frequent meetings, responses to emails after hours as a sign of dedication, physical presence as a proxy for engagement — are, in effect, optimizing for visibility. And visibility is not output.
The phenomenon has a name in management literature: performative work. People who learn that looking busy is what gets recognition will naturally allocate energy to looking busy — not to delivering results. The incentive system creates the behavior. Leaders who then complain that "people here work a lot but produce little" built exactly what the incentive environment told them to build.
The most costly thing, however, is not the performance work of those who remain. It is the way out for those who are not willing to perform. High performers — who are clear about their own value and market options — are the first to walk away from cultures of excess because they can. Those who stay are often those with the fewest alternatives. The result is silent adverse selection: hustle culture retains the least mobile and loses the most valuable.
How a leader should look at this
For those who lead organizations, concrete change starts elsewhere: instead of managing hours, structure work so that each person's time converts as much as possible into real output. This change of perspective seems simple and rarely is — it requires changing the rituals, processes and criteria of recognition that the culture of the occupation has crystallized over the years.
Companies like Basecamp, Buffer, and Doist have built asynchronous work cultures and clear hour limits and produced results above the market average in their industries. Shopify eliminated much of its meeting structure in 2023 and reclaimed hundreds of hours of focused work per week for each employee. Microsoft conducted four-day week experiments in Japan and saw a 40% increase in productivity — not despite the reduction in hours, but because of it.
What these cases have in common is that the leaders were honest about what really generated results — and were willing to cut what only generated the appearance of results. Answering this question honestly often reveals that a significant fraction of what passes for work in organizations—meetings without a clear agenda, projects without a defined owner, reports no one reads—is organized waste. Cutting this waste means respecting time as the most scarce and non-renewable resource there is.
For leaders who still associate long hours with commitment, the most useful question to ask is simple: Is your best performer, the person whose departure would scare you the most, still here? If so, ask why. If you've already left, you probably already know the answer.
