What Should You Do When an Employee Raises a Formal Grievance?

Thursday, 26 March 2026

Receiving a formal grievance from an employee can feel unsettling for any business owner or manager. However, how you respond is critical.

For many employers, particularly those without in-house HR, having access to reliable HR support in Dorset can make this process far more manageable.

Once an employee submits a complaint in writing, it must be handled properly and in line with your grievance procedure and Acas guidance. Failing to follow the correct process can significantly increase the risk of an employment tribunal claim.

A structured and fair response protects both the employee and the business while helping resolve the issue in a professional way.

Below are the key steps you should take when dealing with a formal grievance at work.

1. Acknowledge the grievance quickly

When an employee raises a formal grievance, respond promptly. Even a short acknowledgement shows that the concern is being taken seriously.

Your response should:

- Confirm the grievance has been received
- Outline the next steps in the grievance process
- Provide an approximate timeframe for the investigation
- Reassure the employee that the matter will be considered fairly

Ignoring or delaying a response can cause unnecessary anxiety and may escalate the situation.

Businesses that work with HR support for small businesses often have templates and guidance ready to handle this stage correctly.

2. Decide whether it should be handled formally or informally

Not every workplace concern requires a formal process, but once something is submitted in writing, it’s usually best treated as a formal grievance.

As a general guide:

- Written complaints should normally follow the formal grievance procedure
- Issues relating to workplace behaviour, treatment, pay, or employment rights should be handled formally
- Minor misunderstandings may sometimes be resolved through informal discussion

However, you should avoid dismissing or minimising a complaint once it’s been formally raised.

If you're unsure, seeking advice from professionals offering HR in Dorset can help you make the right call early on.

3. Follow your grievance procedure

Your internal employee grievance procedure provides the framework for handling complaints fairly and consistently.

This typically involves:

- Appointing an impartial person to handle the grievance
- Explaining the process clearly to the employee
- Ensuring the procedure is followed consistently

Adhering to the process is essential. Tribunals often look closely at whether you followed proper Acas grievance guidance when handling workplace complaints.

4. Carry out a fair and thorough investigation

A proper investigation is at the heart of resolving an employee grievance.

Avoid assumptions and gather all relevant information before making any decisions.

This may include:

- Speaking with the employee who raised the grievance
- Interviewing any witnesses or individuals involved
- Reviewing documents, emails, or other evidence
- Keeping clear records of meetings and findings

Poor or rushed investigations are one of the most common reasons employers lose employment tribunal cases.

Many small businesses choose outsourced HR support in Dorset to ensure investigations are handled objectively and professionally.

5. Hold a grievance meeting

A grievance meeting allows the employee to explain their concerns in more detail.

Employees are usually entitled to bring a companion, such as a colleague or trade union representative.

During the meeting:

- Listen carefully to the employee’s concerns
- Ask questions to clarify the facts
- Remain calm and professional

The goal is to fully understand the situation before reaching a decision.

6. Make a fair and evidence-based decision

After completing the investigation, review the evidence and determine the outcome of the grievance.

Your decision should clearly explain:

- What the investigation found
- The conclusions reached
- Any actions that will follow

Employees may not always agree with the outcome, but they should be able to see that the process was fair and objective.

7. Confirm the outcome in writing

The final step in the employee grievance process is confirming the decision in writing.

The outcome letter should:

- Summarise the grievance raised
- Outline how the investigation was conducted
- Explain the decision reached
- Confirm any actions or next steps
- Inform the employee of their right to appeal

A clear written record is essential if the situation later develops into a dispute.

8. Address the underlying cause

An employee grievance often highlights wider workplace issues.

You should consider whether the complaint points to:

- Communication breakdowns within the team
- Unclear expectations or policies
- Management training needs
- Workplace culture problems

Addressing the root cause can help prevent future grievances and improve the working environment.
