It is good practice for employees dismissed for redundancy to be offered the right to appeal the dismissal. There is however no set requirement to do so. The ACAS Code of Practice on Disciplinary and Grievance Procedures does not apply to redundancy dismissals. It is also unlikely that an Employment Tribunal would deem an otherwise fair dismissal unfair because of a failure to offer an appeal. The main advantage of an appeal process to the employer is to allow them to argue that any unfairness in the original decision to dismiss has been “cured” by a complete rehearing on appeal.
The Acas Advisory booklet Redundancy handling (which has no statutory effect) suggests that it would be good practice to offer the employee a right of appeal since this can enable disputes to be resolved internally without recourse to Employment Tribunals.
