If a participant in the testing program refuses to submit to a COVID-19 test, the agency may pursue disciplinary action and bar the employee from the workplace.
“If the agency bars the employee from the workplace, and the nature of the employee’s work does not allow for it to be performed outside the workplace, the employee must be placed on paid administrative leave until the question of disciplinary action is resolved,” the administration said. “In pursuing an adverse action, the agency must also follow normal processes to provide the required notice to the employee.”
