Amazon is reverting to its pre-pandemic policy and will require corporate employees to be in the office five days a week starting next year, CEO Andy Jassy said Monday.

Jassy said in a message shared with employees that the company’s leadership had been thinking in recent months about how to better “invent, collaborate and be connected enough to each other” to deliver the best results for customers and the business.

The company decided that bringing employees back into Amazon offices five days a week instead of the three currently required was a way to address that issue, the CEO said.

“When we look back over the last five years, we continue to believe that the advantages of being together in the office are significant,” Jassy wrote in the memo, which Amazon also shared on its website. The policy takes effect on January 2, 2025.

Like many other companies, Amazon’s corporate employees worked remotely during the COVID-19 pandemic, when the company saw massive gains from a boost in online shopping. In 2021, the tech giant implemented a policy that allowed leaders to determine how their teams worked.

In February 2023, Amazon asked all employees to come back to the office for three mandatory days, resulting in some protests from workers.

A few months later, Jassy said employees who were not happy about the change should learn to “disagree and commit.” He also issued somewhat of a subtle threat, saying it was “probably not going to work out” for those who refused to do so.

In his note on Monday, Jassy said the company has observed that it is easier for employees to “learn, model, practice and strengthen” Amazon’s culture and brainstorm when they’re together in person.

“If anything, the last 15 months we’ve been back in the office at least three days a week has strengthened our conviction about the benefits,” he said.

In Boston, Amazon’s second Seaport District tower at One Boston Wharf is nearing completion. The company inked a lease deal with WS Development for 630,000 square feet of office space in the 707,000-square-foot building in 2021, before construction began, to compliment the 525,000 square feet it leases from WS in 111 Harbor Way next door. Jassy’s mandate would, at a stroke, place over 11 percent of the Seaport’s office space on a five-day in-office schedule.
