California's COVID-19 Impact Notice is a document issued to employers, workers, and members of the public by the California Department of Industrial Relations (DIR). It is intended to provide detailed information about the impacts of the coronavirus (COVID-19) pandemic on California workplaces. The notice includes information about the current health orders in place, the safety measures employers and workers must take to protect each other, and the resources available to help employers and workers mitigate the impacts of the pandemic. There are two types of California COVID-19 Impact Notice: a general notice and a notice specific to construction sites. The general notice applies to all workplaces in the state, while the construction-specific notice covers worksites in the construction, industrial, and manufacturing industries. Both notices include information about the safety measures employers and workers must take, such as wearing face coverings, providing proper ventilation, and implementing social distancing protocols. They also provide resources for employers and workers, such as the California Workplace Health and Safety Program, the California Occupational Safety and Health Administration (Cal/OSHA), and the California Department of Public Health.
