(CNN) America's largest retailer will require all workers to wear face coverings starting Monday as the coronavirus pandemic ravages communities nationwide.

The CEOs of Walmart and its Sam's Club wholesale stores made the announcement in a statement Friday.

"We will begin requiring that associates wear masks or other face coverings at work. This includes our stores, clubs, distribution and fulfillment centers, as well as in our corporate offices," it said.

Customers will also be encouraged to cover their faces, although it will not be mandatory. Walmart will provide all employees with a face covering, or they can bring their own.

"We hope this step will promote safety and consistency across all of our facilities and be of comfort to our customers and members. However, it's important to remember that face coverings are simply an additional health precaution. They do not guarantee against the spread of this virus," the statement said.
