Walmart shoppers will now see a big change in the stores this week. The retail giant started requiring all staff members to wear face masks, saying that following the Centers for Disease Control and Prevention’s recommendation is in “everyone’s best interest”. Monday’s mandate affects all 1.5 million employees, including those working in its big-box store Sam’s Club, the distribution and fulfillment centers, and its corporate headquarters. Employees can bring their own face coverings or wear one provided to them. Have you started wearing a mask when out in public? How long has it taken to become accustomed?
