A federal appeals court has reinstated the Biden administration’s vaccine and testing requirement for private businesses that covers about 80 million American workers. The ruling by the 6th U.S. Court of Appeals in Cincinnati lifted a November injunction that had blocked the rule from the Occupational Safety and Health Administration, which applies to businesses with at least 100 workers. In the decision Friday, the 6th Circuit noted that OSHA has historical precedent for using wide discretion to ensure worker safety and “demonstrated the pervasive danger that COVID-19 poses to workers—unvaccinated workers in particular—in their workplaces.”
