Facebook announced Monday that it will require all campus employees to wear masks irrespective of their vaccination status.

The move comes after Facebook announced Wednesday that it would require U.S. workers returning to its offices to be vaccinated.

“As our offices reopen, we will be requiring anyone coming to work at any of our US campuses to be vaccinated,” VP of People Lori Goler said in a statement last week.

The latest policy will be implemented on Wednesday and will continue to stay in effect. There is no official date for when the mandate will end.

“The health and safety of our employees and neighbors in the community remains our top priority,” Facebook said in a statement.

“Given the rising numbers of COVID cases, the newest data on COVID variants, and an increasing number of local requirements, we are reinstating our mask requirement in all of Facebook’s U.S. offices, regardless of an employee’s vaccination status.”

The decision follows as many other companies and local governments for multiple counties in the San Francisco Bay Area that have also started similar protocols again.

Tech giants, including Google and Apple, have been among the first to reinstate mask mandates when employees are indoors on working property.

Companies such as Disney, Wall Street Journal, Walmart, Home Depot and Target have also implemented a vaccine mandate for some employees.
