Six counties in southeastern Michigan – including Wayne, Oakland, Macomb and Washtenaw – are again listed by the CDC as having high Covid-19 levels. The CDC recommends wearing masks indoors in public settings in those counties.
Ford said it was temporarily reinstating a face mask requirement at all its plants located in areas deemed high-risk by the CDC.
Stellantis said starting on Monday, "company-issued face masks will again be required for employees, contractors and visitors at all Stellantis facilities" in those Michigan counties. The company said "it is expected the requirement will be in place for the next two weeks."
GM said it "will be implementing Covid-19 protection measures at our facilities in Oakland, Wayne, Livingston and Macomb counties given the CDC has listed them as high risk".
The United Auto Workers union said on Sunday if "a facility is located in high-risk counties as identified by the CDC, they will require masking and physical distancing".
GM and Ford have their headquarters in Wayne County, while Stellantis' North American headquarters is in Oakland County. All three have numerous factories in southeastern Michigan.
The CDC said 4.25% of US counties are listed as having high levels of Covid-19.
