The code of practice for disciplinary issues and dismissal came into force on April 6, 2009. The Acas Code of Practice on Disciplinary and Grievance replaced the Statutory Dispute Procedures. This factsheet explains the Acas disciplinary procedure including the role of the Acas disciplinary hearing and suspension letter and the Acas dismissal procedure.


Acas disciplinary procedures and the Acas dismissal procedure

The Acas Code of Practice on Disciplinary and Grievance Procedures simplified the much-criticised Statutory Dispute Procedures. The Acas Code suggests parties ‘should’, rather than ‘must’ act in a certain way. However, Employment Tribunals ruling on individual cases can:

  • Increase compensation by up to 25 per cent where the employer has ‘unreasonably’ failed to follow the Acas Code;
  • Reduce compensation by up to 25 per cent where the employee has ‘unreasonably’ failed to follow the Acas Code.

The Employment Tribunal has wider discretion to uplift or reduce compensation where either party has unreasonably failed to follow the code. The Employment Tribunal can also choose not to adjust compensation at all.

The Acas Code only applies to disciplinary situations, which includes misconduct and poor performance cases. It explicitly excludes dismissals on the grounds of redundancy or the non-renewal of a fixed-term contract. But, it is still not clear if the non-renewal of a fixed-term contract for reasons of misconduct or poor performance is covered. In addition, an Employment Tribunal found that its application is not necessarily limited to misconduct or poor performance and applied to a Some Other Substantial Reason dismissal because this type of dismissal was not specifically excluded in the Acas Code.

The Acas Code sets out steps employers ‘should’ take when tackling misconduct, poor performance and possibly some other substantial reason dismissals. Different procedural considerations apply to misconduct and capability issues. It is therefore essential managers properly identify when an employee’s inability to perform his or her duties amounts to poor capability and when it amounts to misconduct. Above all employers should seek to ensure they follow a fair procedure to defend against a claim of unfair dismissal.


Investigate the issue

The employer should conduct a reasonable investigation which may involve meetings with the employee or collecting evidence. If paid suspension is necessary, the suspension should be as brief as possible. The employer should make it clear (preferably in writing – Acas suspension letter) that suspension is not in itself a form of disciplinary action, but a neutral act.


Inform the employee of the issues in writing

The letter should include the allegations of misconduct or poor performance and the possible consequences (including the risk of a dismissal where applicable). This should have sufficient detail for the employee to respond at a disciplinary hearing. Any written evidence used by the employer, including witness statements, should be provided to the employee.


Arrange an Acas disciplinary hearing

A hearing (sometimes called an Acas disciplinary hearing) should be scheduled without unreasonable delay, ensuring the employee has time to prepare. The letter should also set out the employee’s right to bring a companion, either a fellow worker or a trade union representative.


Hold the Acas disciplinary hearing

Managers, employees and their witnesses should make every effort to attend. If the employee is consistently unable or unwilling to attend, the employer should make a decision on the available evidence. Each side should give advance notice of any witnesses they intend to call. At the hearing the employer should explain the allegations and go through the evidence. The employee should be allowed to set out their case against their allegations. The employee should have reasonable opportunity to:

  • Ask questions;
  • Present evidence;
  • Call relevant witnesses;
  • Raise points about any information from witnesses.

Inform the employee of decision

This should be given in writing without unreasonable delay and should notify the employee of their right to appeal. If misconduct or poor performance is established, a dismissal would only usually be appropriate if this is gross negligence or gross misconduct (Acas gross misconduct). This can justify dismissal for a first offence, but not without following a disciplinary procedure. Where the outcome is a written warning, including a final written warning, this warning should set out:

  • Nature of the misconduct or poor performance;
  • Improvement required;
  • Timescale for improvement;
  • How long the warning will remain in place;
  • Consequences of further misconduct or failure to improve within the defined period.

Arrange an appeal hearing where necessary

The employee’s appeal should be in writing, specifying the grounds of their appeal. If they bring a Tribunal claim without appealing, their compensation award may be reduced. The appeal should be heard without delay, where possible by a manager who has not been previously involved. The employee can bring a work colleague or trade union representative to the appeal hearing.


Notify employee of final decision

This should be in writing within a reasonable timescale making it clear that this decision is final unless the company has a two-tiered appeal policy.
