Does my employer have to require COVID-19 testing?
According to the Equal Employment Opportunity Commission (EEOC), your employer may screen you for COVID-19. Your employer may ask you if you have experienced or are experiencing COVID-19 symptoms, which include fever, chills, cough, shortness of breath, or sore throat. In compliance with the Americans with Disabilities Act (ADA), your employer should keep any record of employee illness confidential.
Your employer is allowed to ask for a doctor’s note certifying fitness for duty, if your healthcare provider is available to give you one. Also, your employer may take steps to screen employees returning to work on a regular basis following CDC guidelines.
