Microsoft will require its employees and all others to be fully vaccinated before they can return to its U.S. office locations in October.

“As we have done since the beginning of the pandemic, we continue to closely track new developments and adapt our plans as this situation evolves, keeping employee health and safety top of mind,” a Microsoft spokesperson said. “We continue to review the situation on a local basis in each region, country, and state where we work and will adjust dates and policies as needed.”

To be clear, Microsoft isn’t just requiring that employees be vaccinated: This requirement will extend to all vendors and guests, too, so basically everyone who might set foot in the door. The software giant will, of course, accommodate employees who have medical conditions or even religious reasons for not being vaccinated. And those who are caring for family members who don’t qualify for vaccinations, like children and the immunosuppressed, can continue working from home until January.

Microsoft now plans to reopen its U.S. facilities starting October 4, though that date could, of course, shift depending on the situation. Previously, it expected to begin opening its office on September 7.

Google announced last week that it, too, will require employees to be vaccinated before they can return to the office. Other tech firms, like Facebook, have announced similar requirements.
