From the Introduction: "The Chicago Department of Public Health (CDPH) is dedicated to supporting Chicago's workplaces throughout the COVID-19 [coronavirus disease 2019] pandemic. Our role is to inform the City's businesses about public health mitigation strategies in order to prevent and reduce transmission of COVID-19 while maintaining business operations. Communication and cooperation with public health officials is very important. The more public health officials understand about your operation, the more they will be able to help provide specific guidance and options that will be least disruptive. This guide offers resources for non-healthcare workplace settings, including what to do in the event of COVID-19 cases in the workplace and how to mitigate spread. COVID-19 can spread within workplaces and, depending on the type of business, to customers. It is critical that businesses provide employees with clear COVID-19 guidance to protect their health, prevent transmission to others, and minimize disruptions to daily operations within the workplace. This is especially important in settings where COVID-19 vaccination rates of workers and/or customers are low or unknown."
