Workers at Amazon warehouses will once again be required to wear masks, according to a message sent to employees obtained by CNBC Wednesday.
The reimposition of the mask mandate, which was only lifted in November, comes amid a surge in cases of COVID-19 driven by the Omicron variant.
Workers were told they must all wear masks regardless of vaccination status or local rules.
“Your health and safety are of the utmost importance to us,” the notice states. “In response to the rapid spread of the Covid-19 omicron variant in the U.S. and guidance from public health authorities and our own medical experts, face coverings are again required for everyone.”
An Amazon spokesperson did not respond to inquiries from The Hill about mask requirements.
Masks were required for factory workers who were not fully vaccinated prior to Wednesday.
Amazon first stopped requiring masks in May before reviving the mandate in August.
