Yes, under normal circumstances this would be considered a medical exam under ADA and not allowed, but because of COVID-19, the CDC and local Health Departments are allowing this. Keep in mind this should be related to COVID-19 and you should be specific to COVID-19 symptoms (i.e. fever, cough, shortness of breath). All employees should do this consistently and not discriminate based on protected classes. Employers are reminded that doing this can provide a false sense of security. Be sure to continue with CDC recommendations on cleaning and keeping the workplace safe.
