Controversy
In January 2025, an undated video of Subrahmanyan’s New Year address sparked widespread controversy online. In the video, an employee is heard asking why Larsen & Toubro, one of India's largest conglomerates, requires employees to work on Saturdays.[22][23] In response, Subrahmanyan expressed remorse not being able to make employees work on Sundays, stating it would make him happier since he himself works on Sundays.[22][23] He further questioned that what do employees do "sitting at home" and how long could spouses stare at each other, suggesting that employees should "Get to the office and start working" on Sundays instead.[22][24][23] Shortly after the video went viral, Meena Subrahmanyan, his wife, became the target of widespread trolling on social media due to her husband's remarks.[25]
Subrahmanyan justified this stance by citing a conversation with a Chinese individual who claimed that China's longer work hours could enable them to surpass the United States.[22][23] He subsequently endorsed a 90-hour workweek for employees, adding that such effort was necessary for achieving success.[22][23] However, his statements were contradicted by a 2021 United Nations report, which highlighted the detrimental effects of excessive work hours on mental and physical health.[26]
The remarks reignited concerns about toxic work environments in India, especially following the 2024 suicide of an Indian Chartered Accountant and death due to heart attack of another one attributed to work pressure.[27] This controversy also brought attention to Subrahmanyan’s substantial remuneration in 2024, which amounted to ₹510,000,000 (approximately $6,000,000 in 2025), compared to L&T’s median employee salary of ₹955,000 (approximately $11,000 in 2025).[28]
