On Thursday, the Biden administration released guidance for federal employees stating that there will be no requirement of vaccination or disclosure of vaccination status prior to returning to the workplace. As the largest employer in the U.S., the federal government will serve as a model employer for post-pandemic operating norms. The guidance requires agencies to submit detailed reopening plans by July 19th.
