(Reuters) -The U.S. Department of Labor issued an emergency rule on Thursday for controlling COVID-19 and protecting workers in healthcare settings, but stopped short of extending the rule to other high-risk industries. The rule by the Occupational Safety and Health Administration (OSHA) aligns with existing non-binding guidance from the agency, but gives workers greater leverage to demand protections and provides for stricter enforcement and fines. The agency also provided non-binding guidance for unvaccinated workers in high-risk settings, such as shifting some of those workers to off-hours, installing physical barriers on assembly lines and staggering breaks.
