Grievance

A formal complaint raised by an employee about a workplace issue such as unfair treatment, unsafe conditions, discrimination, or a breach of their employment contract or company policy.

What Is a Grievance?

Key Takeaways

  • A grievance is a formal complaint an employee raises when they believe their employer, manager, or colleague has treated them unfairly, violated a policy, or breached their rights.
  • Grievances differ from everyday complaints. A complaint becomes a grievance when it's submitted through a formal channel, usually in writing to HR or a manager.
  • Common grievance topics include bullying, harassment, discrimination, unfair pay, unsafe working conditions, workload issues, and contract breaches.
  • Unresolved grievances cost organisations money through turnover, absenteeism, reduced productivity, and potential legal claims.
  • Every employer should have a clear grievance procedure. In the UK, the ACAS Code of Practice sets out minimum standards that employment tribunals consider when awarding compensation.

A grievance is a formal expression of dissatisfaction. It's the moment an employee stops complaining informally and puts their concern in writing. That shift matters. Once a grievance is raised, the employer has a legal and ethical obligation to investigate and respond. The word "grievance" carries weight. Most employees don't use it lightly. By the time someone files a formal grievance, they've usually tried to resolve the issue informally, spoken to their manager, and felt that nothing changed. That's why grievances are a lagging indicator of workplace problems. If you're getting a lot of them, something upstream is broken. Grievances can be individual (one employee raising a concern about their own treatment) or collective (a group of employees raising the same issue). Individual grievances are far more common. Collective grievances often signal systemic problems that require broader organisational change rather than case-by-case resolution.

Types of Workplace Grievances

Grievances fall into several categories. Understanding the type helps determine the right investigation approach and resolution path.

TypeExamplesTypical Resolution Path
InterpersonalBullying, harassment, personality conflicts, management styleInvestigation, mediation, or management action
ContractualUnpaid wages, denied benefits, changes to terms without consentContract review, payroll correction, legal assessment
DiscriminationUnfair treatment based on protected characteristics (race, gender, age, disability)Formal investigation, possible legal escalation
Work EnvironmentUnsafe conditions, excessive workload, inadequate equipmentRisk assessment, facilities review, workload audit
Policy ApplicationInconsistent application of company policies, unfair promotion decisionsPolicy review, management training, decision reversal
RetaliationAdverse treatment after whistleblowing, raising concerns, or filing a previous grievanceUrgent investigation, legal review, protective measures

Root Causes of Employee Grievances

Most grievances don't appear out of nowhere. They build over time from recurring issues that management either doesn't see or doesn't address.

Poor management behaviour

The single biggest driver of grievances. Managers who micromanage, play favourites, communicate poorly, or fail to give credit create frustration that eventually becomes formal complaints. CIPD data shows that 54% of all individual grievances relate to the behaviour of a direct line manager. Training managers in basic people skills, including how to give feedback, handle disagreements, and treat employees consistently, prevents more grievances than any policy document.

Lack of transparency

When employees don't understand why decisions are made, they assume the worst. Promotion decisions made behind closed doors. Pay rises given without clear criteria. Reorganisations announced without explanation. Transparency doesn't mean sharing every detail. It means giving employees enough context to understand that decisions are fair, even if they don't agree with the outcome.

Inconsistent policy enforcement

Nothing breeds grievances faster than rules that apply to some people but not others. If one employee gets a verbal warning for being late and another doesn't, that's a grievance waiting to happen. HR teams need to audit how policies are applied across departments and managers to spot inconsistencies before employees do.

The Cost of Unresolved Grievances

Ignoring grievances doesn't make them go away. It makes them more expensive.

How to Handle a Grievance Effectively

The way you handle a grievance matters as much as the outcome. Even if the final decision goes against the employee, a fair process maintains trust.

  • Acknowledge the grievance in writing within 2-3 business days. Speed signals that you take the complaint seriously.
  • Assign an impartial investigator. Someone with no prior involvement in the issue and no reporting relationship to either party.
  • Interview the employee first. Let them explain the full picture before you gather evidence or speak to others.
  • Gather evidence methodically: emails, messages, CCTV footage, attendance records, witness statements, policy documents.
  • Keep detailed records of every step. Document what you did, when, and why. These notes become critical if the case reaches a tribunal or court.
  • Communicate progress to the employee regularly. Silence breeds anxiety and suspicion.
  • Reach a decision based on the balance of evidence. Explain the reasoning clearly, not just the outcome.
  • Offer the right to appeal. A fresh pair of eyes reviewing the decision is both good practice and a legal requirement in many jurisdictions.

Preventing Grievances Before They Arise

The best grievance is the one that never gets filed. Prevention requires proactive effort from HR and management.

Build strong manager capability

Invest in training managers on conflict resolution, active listening, giving feedback, and having difficult conversations. Most grievances trace back to a manager who either created the problem or failed to address it early. Regular manager check-ins with HR can catch issues before they escalate.

Create safe informal channels

Employee hotlines, skip-level meetings, anonymous surveys, and open-door policies give employees ways to raise concerns before resorting to formal grievances. These channels only work if employees trust that using them won't result in retaliation. Publicise examples of issues resolved through informal channels (without identifying individuals).

Conduct regular engagement surveys

Pulse surveys and annual engagement surveys can identify pockets of dissatisfaction before they become formal complaints. Look for patterns: departments with low scores on fairness, trust in management, or communication are likely sources of future grievances. Act on the data visibly.

Frequently Asked Questions

Can an employee raise a grievance after leaving the company?

Yes. Former employees can raise grievances after their employment ends, though the practical options for resolution are more limited. In the UK, failing to address a post-employment grievance can affect tribunal compensation. In the US, former employees can file EEOC complaints and lawsuits. Many employers include a clause in their grievance procedure explaining how post-employment grievances are handled.

Can an employee be disciplined for raising a grievance?

No. Disciplining or dismissing an employee for raising a genuine grievance is victimisation and likely unlawful. In the UK, it can lead to an automatic unfair dismissal claim. In the US, it can constitute retaliation under anti-discrimination laws. The exception is grievances raised in bad faith or as a tactical manoeuvre to delay disciplinary proceedings. Even then, the employer must tread carefully and document the reasoning.

What's the difference between a grievance and a complaint?

A complaint is informal. An employee telling their manager they're unhappy about something is a complaint. A grievance is formal. It's raised in writing through the company's grievance procedure and triggers a structured investigation and response process. The distinction matters because formal grievances create legal obligations and documentation trails that informal complaints don't.

Should an employee raise a grievance before going to an employment tribunal?

In the UK, employees must contact ACAS for Early Conciliation before bringing most tribunal claims. While raising an internal grievance isn't legally required before going to tribunal, failing to do so can reduce compensation by up to 25% under the ACAS Code. From a practical standpoint, raising a grievance first gives the employer a chance to resolve the issue internally, which is usually faster and less costly for both sides.

How long should a grievance investigation take?

There's no legal time limit, but ACAS recommends completing investigations "without unreasonable delay." Most organisations aim to conclude within 2-4 weeks. Complex cases involving multiple witnesses, external evidence, or overlapping legal proceedings may take longer. The key is to keep the employee informed about progress and reasons for any delays. Unexplained silence during a grievance investigation is one of the fastest ways to lose an employee's trust.
