SCHEDULE ACAS ARBITRATION SCHEME
XV. OUTLINE OF PROCEDURE BEFORE THE HEARING Requests for attendance of witnesses 92 Although the arbitrator has no power to compel the attendance of anybody at the hearing, the arbitrator may draw an adverse inference if an employer who is a party to the arbitration fails or refuses to allow current employees or other workers (who have relevant evidence to give) time off from work to attend the hearing, should such an employer be so requested.
