Federal Employee Accountability Act of 2019 or FEAA This bill provides additional statutory authority for federal agencies to discipline employees. Specifically, agencies may remove or demote (i.e., reduce the grade or pay of) employees for performance or misconduct without proving that the adverse action promotes the efficiency of the service. The bill provides a statutory definition of the term "misconduct." An adverse action may be appealed to the Merit Systems Protection Board. The bill sets forth requirements and procedures for such appeals.
