The debate surrounding remote work has reached a fever pitch in today’s workplace: Is enabling employees to work from home a few days a week beneficial for their productivity, career growth, and overall job satisfaction? Nicholas Bloom, a prominent economist from Stanford University, has delved into this issue with groundbreaking research highlighting the advantages of hybrid work schedules for employees and employers alike. In a recently published study in Nature, Bloom presents compelling findings from an experiment conducted at Trip.com, one of the world’s largest online travel agencies based in China. The study involved over 1,600 employees and revealed that those who worked from home for two days a week exhibited levels of productivity and career progression comparable to their counterparts who worked exclusively from the office.

Under the hybrid model, Trip.com saw a significant reduction in employee turnover, with resignations dropping by 33 per cent. This reduction in turnover, particularly among groups such as women, non-managers, and employees with long commutes, translated into substantial cost savings, amounting to millions of dollars for the company.

“The evidence is clear: Hybrid work represents a triple win for enhancing employee productivity, performance, and retention,” asserts Bloom, who holds the William D. Eberle Professorship of Economics at Stanford’s School of Humanities and Sciences and is a senior fellow at the Stanford Institute for Economic Policy Research (SIEPR).

These findings carry significant weight, considering that approximately 100 million workers worldwide now engage in some form of hybrid work arrangement, a trend accelerated by the COVID-19 pandemic. This diverse group includes professionals like lawyers, accountants, marketers, and software engineers, many of whom hold college degrees or higher qualifications. However, despite the evident benefits, hybrid work faces criticism from influential business leaders such as Elon Musk of Tesla and Jamie Dimon of JPMorgan Chase. These critics argue that remote work diminishes employee training, stifles innovation, and erodes corporate culture when employees are not physically present five days a week.

Bloom contends that these critiques often conflate hybrid work with fully remote arrangements, neglecting nuances crucial to understanding its impact. Most research on remote work has focused on roles like customer support or data entry, yielding mixed results that tend towards the negative. Bloom suggests that the challenges of fully remote work stem largely from inadequate management practices. As one of the few randomised control trials analysing hybrid work configurations—where employees work offsite for two or three days a week and onsite for the remainder—Bloom’s study provides valuable insights for multinational corporations, many of which share similarities with Trip.com.

“This study provides compelling evidence supporting why 80 percent of US companies now offer some form of remote work, and why the remaining 20 percent may be paying a price,” Bloom asserts. The research represents the most extensive study on hybrid work involving university-educated professionals, employing the gold standard of research methods—the randomised controlled trial. This approach allowed Bloom and his co-authors, Ruobing Han of The Chinese University of Hong Kong and James Liang of Peking University, to attribute the observed benefits to Trip.com’s hybrid experiment directly. During the six-month trial in 2021, Trip.com implemented a policy where employees with odd-numbered birthdays worked from home two days a week, contrasting with those with even-numbered birthdays who attended the office daily. The study participants included 395 managers and 1,217 non-managers with undergraduate degrees, predominantly in engineering, marketing, accounting, and finance roles at the company’s Shanghai office. About 32 per cent of the participants held postgraduate degrees, primarily in computer science, accounting, or finance. Most were in their mid-30s, half had children, and 65 per cent were male.

The study’s findings underscore that hybrid work benefits employees and enhances organisational outcomes. Data from performance reviews, promotion rates, and comparative analyses of software code output by Trip.com’s engineers revealed no decline in productivity or career advancement under the hybrid model. Instead, the model substantially boosted employee retention rates, particularly among non-managers. Managers, however, exhibited similar resignation rates regardless of their work arrangement. Bloom and his colleagues also identified misconceptions among employees and managers regarding hybrid work. Many employees, especially women, hesitated to volunteer for Trip.com’s hybrid trial due to concerns about potential negative perceptions of needing to be present in the office full-time. Additionally, managers initially anticipated a decline in productivity with remote work, only to revise their views by the trial’s conclusion.

In conclusion, Bloom’s study provides a compelling case for the benefits of hybrid work. It dispels fears of negative impacts when managed effectively and highlights the potential for maintaining mentorship, fostering a vibrant company culture, and stimulating innovation. From an economic policymaking standpoint, hybrid work emerges as a strategy with overwhelmingly positive outcomes, benefiting almost all stakeholders involved.
