The statutory Acas Code of Practice on Disciplinary and Grievance Procedures states that employers should allow an employee to appeal against any formal decision made. Also, if a decision is taken to dismiss an employee, the employer should inform the employee as soon as possible of the reasons for the dismissal, the date on which the employment will end, the appropriate period of notice and their right of appeal. Further, employees should let employers know the grounds for their appeal in writing, and the appeal should be dealt with impartially and, where possible, by a manager who has not previously been involved in the case. According to the Acas guide: Discipline and grievances at work (pp.34-35): • appeals may be raised by employees on any number of grounds, eg new evidence, undue severity or inconsistency of the penalty an appeal must never be used as an opportunity to punish the employee
