Disney CEO Bob Iger told hybrid employees on Monday they must return to corporate offices four days a week starting March 1, according to an email obtained by CNBC.

In the email, Iger stressed the importance of in-person collaboration.

“As I’ve been meeting with teams throughout the company over the past few months, I’ve been reminded of the tremendous value in being together with the people you work with,” Iger wrote. “As you’ve heard me say many times, creativity is the heart and soul of who we are and what we do at Disney. And in a creative business like ours, nothing can replace the ability to connect, observe, and create with peers that comes from being physically together, nor the opportunity to grow professionally by learning from leaders and mentors.”

During the pandemic, many firms went for work-from-home or hybrid work models to minimize the spread of Covid-19. As vaccination rates soared and cases and hospitalization rates declined, companies like Disney started reconsidering that staff returns to offices.

Iger’s four-day-per-week stipulation is stricter than other companies’ decisions which have opted for two or three mandated in-office days for hybrid employees. The decision comes less than two months after he was reinstated as the CEO of the company, promising a two-year stint that would spark renewed growth for the company and develop a successor to take his place.

Iger’s return in November came days after former CEO Bob Chapek said he planned to slash costs at the company, which had been burdened by swelling costs at its streaming service, Disney+. Iger’s return also comes as legacy media companies contend with a rapidly shifting landscape, as ad dollars dry up and consumers increasingly cut off their cable subscriptions in favor of streaming.
