Understand the impact on productivity, health, and work-life balance in today’s competitive world
The concept of a 90-hour workweek has been a topic of significant debate in recent years, particularly in competitive industries such as technology, finance, and entrepreneurship. The discussion has gained renewed momentum following comments from prominent industry leaders advocating for extended work hours as a means to achieve extraordinary success. While some see long hours as a pathway to innovation and growth, others emphasize the risks of burnout and declining productivity associated with overworking.
This article delves into the reality of 90-hour workweeks, incorporating insights from recent statements, industry trends, and data that highlight the impact of such demanding schedules.
Renewed Focus on 90-Hour Workweeks
The idea of a 90-hour workweek recently resurfaced in public discourse after remarks made by Larsen & Toubro (L&T) Chairman S.N. Subrahmanyan. Subrahmanyan suggested that employees should work on Sundays, effectively endorsing extended workweeks to achieve professional success. His comments were framed as a call to action for employees to put in extra effort and commitment, especially in industries that demand rapid results and high levels of performance.
However, these statements have sparked a polarizing response from both corporate leaders and the general public. While some industry leaders agree that long hours may be necessary during critical periods, others caution against adopting such practices as a norm. Critics argue that sustained 90-hour workweeks are unsustainable and could lead to severe consequences for employee health and overall productivity.
Diverging Opinions Among Industry Leaders
The idea of working long hours has long been a hallmark of “hustle culture,” with many influential entrepreneurs romanticizing relentless dedication. Proponents of extended work schedules often cite examples of successful startups and companies that relied on intensive efforts during their formative years.
In contrast, other industry leaders have highlighted the negative effects of excessive work. Harsh Mariwala, Chairman of Marico Ltd, emphasized that the quality of work and the passion brought to tasks matter far more than the sheer number of hours clocked. Similarly, Harsh Goenka, Chairman of RPG Enterprises, pointed out the importance of work-life balance, suggesting that excessive hours could lead to burnout and counterproductive outcomes. These leaders stress the need for a more balanced approach to work that prioritizes employee well-being without compromising performance.
The Broader Implications of Overworking
Recent data sheds light on the impact of extended work hours on employee health and productivity. A 2025 survey by Deloitte revealed that 77% of professionals reported experiencing burnout in their current roles, with long work hours identified as a major contributing factor. The survey also highlighted that employees working excessive hours often face challenges such as reduced focus, decreased creativity, and poor decision-making abilities.
The World Health Organization (WHO) has also weighed in on the issue, noting that working 55 hours or more per week is associated with a 35% increased risk of stroke and a 17% increased risk of heart disease compared to a standard 40-hour workweek. These findings emphasize the physical toll of prolonged work hours and the need for organizations to reconsider their expectations around employee output.
Global Perspectives on Work Culture
Cultural perceptions of work hours vary widely across the globe. In China, the “996” work culture—working from 9 a.m. to 9 p.m., six days a week—has been both praised for driving economic growth and criticized for its detrimental effects on workers’ health. The Chinese government has introduced measures to address these concerns, but the practice remains common in fast-paced industries like technology and manufacturing.
In contrast, some Western countries are adopting more flexible approaches to work. Companies in Europe and North America have experimented with four-day workweeks, reporting increased productivity, employee satisfaction, and better work-life balance. These experiments suggest that reducing work hours without sacrificing efficiency is possible and could serve as a viable alternative to extended workweeks.
The Science Behind Productivity and Work Hours
Research continues to debunk the myth that longer hours always equate to higher productivity. Studies from the Organisation for Economic Co-operation and Development (OECD) indicate that productivity begins to decline significantly when employees work more than 50 hours per week. For those working 70 hours or more, the additional output is negligible, raising questions about the efficiency of such schedules.
Furthermore, data from workplace health organizations show a direct correlation between extended work hours and mental health issues such as anxiety, depression, and chronic stress. Prolonged workweeks can also strain personal relationships and reduce overall job satisfaction, creating a cycle of disengagement and inefficiency.
Challenges in Implementation
While some companies embrace extended hours to meet deadlines or achieve rapid growth, the practice often comes with challenges. In 2024, a high-profile fintech company faced backlash after employees reported health issues and low morale caused by prolonged work schedules. The controversy forced the organization to revise its policies, introducing wellness initiatives and mandatory breaks to support employees.
At the same time, there are instances where companies have successfully managed high-pressure environments by balancing intense work periods with adequate recovery time. Leadership teams that prioritize clear communication, realistic goals, and mental health resources tend to achieve better outcomes in both productivity and employee satisfaction.
Balancing Work and Well-Being
The debate surrounding 90-hour workweeks highlights the need for organizations to strike a balance between ambition and sustainability. While short-term bursts of intense effort may be necessary in specific situations, they should not become the standard. Companies must focus on creating environments that foster innovation and productivity without compromising employee well-being.
To achieve this, many organizations are turning to solutions such as hybrid work models, flexible schedules, and investments in mental health resources. Automation and artificial intelligence are also playing a role in reducing workloads, allowing employees to focus on high-value tasks while minimizing repetitive duties.
The reality behind 90-hour workweeks is complex, influenced by cultural, organizational, and individual factors. While some industry leaders advocate long hours as a means to achieve extraordinary success, others caution against the physical, mental, and emotional toll of such practices. Data and expert insights increasingly point to the importance of sustainable work cultures that balance productivity with well-being.
As the global workforce evolves, organizations must adapt by prioritizing employee health, promoting realistic expectations, and exploring innovative approaches to work. By fostering a healthier and more balanced work environment, companies can achieve long-term success without sacrificing the well-being of their teams.
