HR considerations
UK employment law and best practice
This template is designed to support the process, but the document should be used alongside the relevant HR procedure and applied to the circumstances of the individual case.
Formal grievance procedure
When an employee raises a formal grievance, employers should arrange a formal meeting without unreasonable delay and give the employee an opportunity to explain their grievance, provide evidence and discuss how they would like it resolved. Acas recommends allowing enough time for the employee to prepare for the meeting. https://www.acas.org.uk/grievance-procedure-step-by-step/step-4-the-grievance-meeting
Right to be accompanied
An employee or worker has a statutory right to be accompanied at a grievance meeting where the grievance concerns a complaint about a duty owed by the employer to the worker, such as an alleged breach of contract or legislation. The statutory companion can be a fellow worker, a trade union representative or a certified trade union official. Employers may choose to allow a wider range of companions under their own policy. https://www.acas.org.uk/acas-code-of-practice-on-disciplinary-and-grievance-procedures
Reasonable preparation time
The hearing should be arranged without unreasonable delay while allowing the employee enough time to prepare. The employee should be given sufficient information about the grievance and any relevant evidence being considered so that they can properly explain their position.
Impartiality and investigation
The person handling the grievance should remain impartial and consider information from all relevant sides. Where the issues raised require further investigation, the hearing can be adjourned or further meetings can be arranged before an outcome is reached. https://www.acas.org.uk/grievance-procedure-step-by-step/step-4-the-grievance-meeting
Reasonable adjustments
Employers should consider whether reasonable adjustments are needed for a disabled employee or their companion to enable them to participate effectively in the grievance process. This can include adjustments to the meeting arrangements, communication or who is permitted to attend. https://www.acas.org.uk/reasonable-adjustments
Confidentiality and personal information
Grievance records and evidence should be handled confidentially and only shared with people who need the information for the process, subject to applicable legal requirements. Employers should consider data protection requirements when handling witness statements, correspondence and other employee information. https://ico.org.uk/for-organisations/uk-gdpr-guidance-and-resources/employment/
Outcome and appeal
After considering the grievance and any necessary investigation, the employer should communicate the outcome in writing and provide an appropriate opportunity to appeal in accordance with the organisation's procedure. The Acas Code states that employers should allow an employee to appeal against a formal decision. https://www.acas.org.uk/acas-code-of-practice-on-disciplinary-and-grievance-procedures
Current Acas guidance
Acas is consulting during 2026 on a draft updated Code of Practice on disciplinary and grievance procedures. The draft is not currently the statutory Code, so employers should continue to follow the Code in force and their own grievance procedure, while keeping the position under review. https://www.acas.org.uk/about-us/acas-consultations/code-of-practice-disciplinary-grievance-2026
