Can a Manager Raise a Grievance Against an Employee in the UK?

Managers frequently face challenging workplace situations where an employee’s actions or behaviour threaten team morale or business performance. Many doubt whether they can start a formal grievance process—particularly if they fear it could backfire or affect workplace dynamics. Rest assured, UK law is clear: a manager has the same legal right as any employee to raise a formal grievance.

Under the ACAS Code of Practice and the Employment Rights Act 1996, every employee—including those in management—can escalate serious concerns via a written grievance. These protections reflect best practice across England and Wales and include issues such as misconduct, bullying, or breaches of contract by an employee.

A correctly documented grievance, supported by clear evidence, protects you, the company, and ensures a fair, legally robust outcome. Our AI-powered template builder helps you produce an accurate, effective grievance letter in minutes.

What Is a Grievance in the Workplace and When Should a Manager Raise One?

A workplace grievance is a formal, written complaint concerning behaviour or incidents at work that breach company policy or legal standards. Managers can use this process to address more than just gross misconduct—such as repeated insubordination, harassment, health and safety violations, deliberate data misuse, or damage to business reputation.

A manager should escalate to a formal grievance when:

• Informal solutions have failed or are unsuitable;
• The employee’s behaviour or misconduct is repeated, wilful, or serious;
• Business operations, safety, or your professional standing are at risk;
• The issue relates to statutory breaches, including discrimination or whistleblowing.

Is There a Formal Grievance Procedure for Managers in the UK?

Every employer in England and Wales must have a clear, written grievance policy that applies equally to all staff—regardless of seniority. The ACAS Code of Practice requires a structured process that management must follow and that protects both the business and the complainant.

The usual procedure includes:

1. Submit a detailed, formal grievance letter;
2. Employer arranges a prompt, impartial investigation;
3. Attend a grievance hearing to present your case;
4. Await the written outcome and review options to appeal.

Employers cannot ignore or dismiss a grievance simply because it comes from a manager or a senior teammate. A fair, documented approach limits risk of legal claims against the business for bias or discriminatory handling.

What Steps Should a Manager Take to Raise a Grievance Against an Employee?

To ensure compliance and maximise impact, managers must approach grievances in a clear, methodical way. Follow these steps:

1. Try Informal Resolution First
   Arrange a constructive meeting; note outcomes. If risk is high or the matter is severe, escalate immediately.
2. Check Company Policy
   Find and read the formal grievance procedure (in your staff handbook or HR intranet).
3. Draft a Strong Grievance Letter
   Include precise details: names, dates, evidence, desired outcome, and how business interests have been harmed.
4. Gather and Organise Evidence
   Keep all relevant documents, emails, policies, timesheets, and witness statements together.
5. Submit to Appropriate Contact
   This will usually be your HR department or a more senior leader (especially if HR is conflicted).
6. Prepare for Grievance Meetings
   Arrange your supporting evidence and be ready to answer questions factually.
7. Record Every Step
   Document all conversations, submissions, and actions with dates.

What Legal Protections Do Managers Have When Raising a Grievance?

UK employment law (including the Employment Rights Act 1996) protects all employees—regardless of level—from suffering “detriment” or disadvantage for raising a legitimate workplace grievance. This means managers are legally defended from unfair treatment, demotion, loss of bonuses or responsibilities, or outright dismissal, so long as the complaint is genuine.

You cannot lawfully be treated less favourably or threatened for following the correct process to address a workplace issue. The law also prohibits employers from discouraging you from submitting a grievance or retaliating against you after you have done so.

ACAS Code of Practice: Why Is It Essential for Manager Grievances?

The ACAS Code of Practice sets the national benchmark for handling disciplinary and grievance procedures in England and Wales. Courts and tribunals expect every employer—including managers bringing grievances—to follow these standards. Disregarding the Code weakens your position and can result in financial penalties for the business in the event of a claim.

The ACAS Code ensures:

• Prompt and fair treatment of all grievances, regardless of staff level;
• Step-by-step guidance for documentation, meetings, and outcomes;
• Legal compliance and consistency across the workforce.

Key Documents and Evidence Managers Need for a Workplace Grievance

Proving the facts of your case is vital. Managers must gather robust, chronological evidence that substantiates their claims. This includes any material demonstrating the issue, attempts at informal resolution, and impact on the business. Maintaining a clear evidence file enhances your case and demonstrates professionalism.

Common Mistakes Managers Make When Raising Grievances (And How to Avoid Them)

Managers sometimes undermine their own case by:

• Failing to record conversations or keep evidence;
• Skipping company procedures, leading to delay or rejection;
• Submitting vague, emotional, or unfocused grievance letters;
• Not understanding potential implications for wider team morale.

Can Mediation or Alternative Dispute Resolution Help Managers and Employees?

Mediation and alternative dispute resolution (ADR) are powerful tools for resolving workplace issues without escalating to a tribunal. Managers can request mediation at any point to resolve personality clashes, rebuild relationships, or settle issues quickly while keeping the process discreet.

Benefits include:

• Confidentiality and impartiality, reducing tension;
• Faster, less formal outcomes;
• Preservation of working relationships and reputation.

Manager and Employee Grievances: What’s the Difference and Why Does It Matter?

Both managers and employees have equal rights under the law when raising a grievance. However, the power dynamics and potential risks often differ, requiring heightened sensitivity and impartiality when the complainant is a manager.

Frequently Asked Questions

What are valid reasons for a manager to raise a grievance against an employee?

Managers can raise grievances for gross misconduct, recurring breaches of company policy, wilful insubordination, harassment, bullying, confidentiality breaches, and breaches of statutory law. Day-to-day performance issues should typically be handled under your business’s disciplinary process.

Can a manager be disciplined for filing a grievance?

No. As long as your grievance is genuine and not malicious or frivolous, UK law prohibits punitive action for raising concerns. Any demotion or disadvantage could form the basis for a tribunal claim.

How long does a manager have to submit a grievance?

While there is no hard legal deadline, most companies require prompt reporting—usually within two to four weeks of the incident. Always check your policy for specific timeframes.

Can a manager’s grievance be resolved informally?

Yes. Addressing concerns directly and constructively is often best for small or first-time issues. If the behaviour persists, or severity increases, escalate via formal written grievance.

What happens after a manager raises a formal grievance?

The employer will investigate, hold a hearing, make a decision, and confirm this to you in writing. You have the right to appeal if you believe the process or outcome was unfair.

Who investigates when a manager raises a grievance?

Ideally, a neutral party should lead the investigation—usually senior HR staff, a manager unconnected to the issue, or, in sensitive cases, an independent third party.

What if the employee retaliates against the manager?

Retaliation is strictly unlawful under UK law. Note any incidents and escalate immediately—your rights are protected, and you may have grounds for further action.

Are managers protected by anti-retaliation laws?

Yes. The Employment Rights Act 1996 provides full protection for managers against detriment or dismissal due to raising a grievance.

Should managers get legal advice before submitting a grievance?

For complex or high-risk cases, legal input is wise. Our platform offers manager-focused templates, risk checks, and expert support—often a faster and more affordable alternative.
