evidence: As of January 2022, the federal government has issued a series of COVID-19 vaccine mandates affecting federal contractors, private sector employees, healthcare workers, and Head Start Programs. [...] Following the victory of Tennessee and 26 other states at the U.S. Supreme Court, OSHA agreed to withdraw the ETS vaccine mandate. OSHA is instead treating this as a proposed rule subject to the normal notice-and-comment rulemaking process. The rule is not in force during the notice-and-comment process. [...] The U.S. Court of Appeals for the Sixth Circuit denies the federal government’s request to stay the district court’s injunction of the vaccine mandate for federal contractors in Kentucky, Ohio, and Tennessee.
