Workers may be threatened and assaulted as businesses try to put into place COVID-19 prevention policies and practices (e.g., mandatory use of masks, social distancing, and limits on the number of customers allowed in a business). These threats and assaults can come from customers, other employees, or employers.
Based on a 1996 Current Intelligence Bulletin, threats and assaults can happen in any workplace, but may be more likely to occur in retail, services (e.g., restaurants), and other customer- or client-based businesses.
The CDC has launched a webpage which offers strategies to limit violence towards workers that may occur when businesses put in place policies and practices to help minimize the spread of COVID-19 among employees and customers. You can view more here.
