Amazon announced it will postpone its return to office plans to January 2022 as the spread of the Delta variant increases the number of coronavirus cases. Amazon workers were expected to go back to office in early September 2021 as the company announced it wanted to retain its office-centric culture. Amazon's vaccination policy encourages but does not mandate vaccines to workers. In addition, Amazon mask policy allows workers at both offices and warehouses to be unmasked if they have proof of vaccination.
