Grievances at Work: How Managers Should Respond

What Causes Grievances in the Workplace?

Most workplace grievances arise from something a person believes another individual or the organisation:

• did;
• failed to do;
• said;
• failed to say;
• decided;
• failed to explain clearly.

The underlying issue may involve unfair treatment, inappropriate behaviour, inconsistent decisions, poor communication, discrimination, harassment, bullying, workload, pay, working conditions or changes to a person's role.

Managers can prevent many grievances by communicating expectations clearly, treating people consistently and dealing with concerns before they grow. Good first-line manager training helps managers set standards, give feedback and resolve problems before they become formal grievances.

Prevention is valuable, but managers must also know what to do when an employee raises an active concern.

Should a Grievance Be Handled Formally or Informally?

Some workplace concerns can be resolved informally. A private conversation, clearer explanation, apology or agreed change in behaviour may be enough to settle the matter.

However, a formal process may be needed when:

• the matter is serious;
• an informal approach has failed;
• the employee asks for the issue to be handled formally;
• the complaint involves bullying, discrimination, harassment or serious misconduct;
• the facts are disputed and require investigation;
• the potential consequences are significant.

Managers should follow their organisation's grievance policy and seek support from HR where appropriate. UK employers should also take account of the Acas guidance on formal grievance procedures.

Use the FACTS Method to Handle Workplace Grievances

The FACTS method gives managers a structured way to receive, investigate and respond to an employee grievance.

1. Focus on the Precise Complaint

Begin by allowing the employee to explain their concern without unnecessary interruption. Listen carefully and acknowledge the effect the situation has had on them without promising a particular outcome.

Then clarify exactly what is being alleged. Useful questions include:

• What happened?
• What was said or done?
• When and where did it happen?
• Who was present?
• Has it happened more than once?
• What outcome are you seeking?

Avoid relying only on broad labels such as "bullying", "favouritism", "discrimination", "dishonesty" or "toxic behaviour". These words may describe how the employee interprets the situation, but the manager still needs to identify the observable actions, statements and decisions behind them.

A specific event can be investigated. A general judgement about someone's personality is much harder to assess fairly.

2. Ask for Evidence and Impact

Ask what information supports the grievance. Relevant evidence might include:

• emails or messages;
• documents and meeting notes;
• work allocation or performance records;
• dates and details of specific incidents;
• the names of possible witnesses;
• a consistent sequence of events.

You should also ask how the alleged behaviour or decision has affected the employee, their work or the wider team. Understanding the impact helps the manager judge the seriousness and urgency of the concern.

The employee should not be expected to prove the whole case before the grievance is taken seriously. Equally, the number of times an accusation has been repeated does not, by itself, prove that it is correct.

3. Check the Other Perspectives

A fair manager gathers information from all relevant sides. This usually means speaking separately to the person complained about and to any appropriate witnesses.

Present the specific concern calmly and without adding judgemental language. Give the other person a proper opportunity to explain their understanding and provide evidence of their own.

The aim is to establish what happened, rather than create a courtroom-style confrontation or pressure someone into accepting blame.

The manager should also check whether the organisation's rules, expectations and previous decisions were communicated clearly. Some workplace disputes arise because people have been working from different assumptions.

It is also important to recognise the difference between ordinary and investigative conversations. An investigative discussion should be planned carefully, use neutral questions and avoid leading the person towards a preferred answer.

4. Test Whether a Pattern Exists

One incident and a repeated pattern may require different responses. Review comparable situations and ask:

• Has similar behaviour happened before?
• Were other employees treated in the same way?
• Do the documents support either account?
• Are the different accounts broadly consistent?
• Is there another reasonable explanation?
• Has the organisation applied its rules consistently?

Look for evidence that supports the grievance and evidence that challenges it. An investigation should test the complaint fairly rather than searching only for information that confirms an early assumption.

Managers who need to question the people involved may find it useful to follow a structured approach to conducting an investigative interview.

5. Set the Next Action

Once the available information has been reviewed, decide what should happen next. Depending on the circumstances, the appropriate response might include:

• correcting a misunderstanding;
• explaining a decision more clearly;
• agreeing a change in behaviour;
• providing coaching or training;
• using workplace mediation;
• correcting an unfair or inconsistent decision;
• monitoring the situation;
• taking the matter through a formal grievance or disciplinary process;
• deciding that the evidence does not support further action.

Record the outcome, the reasons for the decision, any actions agreed, who is responsible for them and when progress will be reviewed. Communicate the outcome through the appropriate process and explain any available right of appeal.

How Should Managers Respond to Repeated Accusations?

A repeated accusation tells a manager that the concern remains active. It does not automatically reveal whether the allegation is true, mistaken, exaggerated or malicious.

The employee may repeat the concern because:

• they believe it has not been properly addressed;
• similar incidents are continuing;
• their original complaint was misunderstood;
• important evidence has been overlooked;
• they do not understand the outcome;
• they believe the matter presents a continuing risk.

There may also be situations where the person has misinterpreted events, is repeating a fixed belief or is using the accusation to apply pressure.

The manager should keep reasonable explanations open until the evidence has been considered. They should not respond by making an unsupported accusation against the complainant.

For example, saying, "You keep accusing other people of dishonesty, so perhaps you are the dishonest one," does nothing to establish what happened. It merely adds a second accusation.

Managers should avoid amateur psychological diagnoses and concentrate on conduct that can be observed, described and investigated.

A Workplace Grievance Example

Suppose an employee repeatedly complains that their team leader gives the best assignments to two favoured colleagues.

A poor management response would be:

"You are obsessed with favouritism. The real problem is probably your jealousy."

This attacks the employee's character and leaves their original concern unanswered.

A better manager asks for specific examples, dates and details of the assignments concerned. They review how work was allocated, speak privately to the team leader and compare the decisions with the stated allocation criteria.

The investigation might show that most assignments were allocated reasonably, but the criteria were never properly explained. It might also reveal one occasion when the normal process was applied inconsistently.

The manager can then correct the inconsistent decision where possible, publish clearer allocation criteria and review the pattern after an agreed period.

This response neither accepts nor dismisses the allegation automatically. It uses the grievance as the starting point for a fair examination.

Treat Serious Workplace Complaints Properly

Complaints involving discrimination, harassment, bullying, fraud, safeguarding, health and safety, whistleblowing or serious misconduct should not be treated as ordinary disagreements.

Managers should follow the correct organisational policy and involve HR, safeguarding leads or other appropriate specialists. Confidentiality should be protected as far as reasonably possible, and conclusions should not be reached before the relevant facts have been examined.

Some concerns that appear to be personal grievances may also involve wider wrongdoing or matters of public interest. Managers should therefore avoid assuming that every complaint belongs under the same procedure.

How Can Managers Prevent Future Grievances?

Once a grievance has been resolved, look beyond the individual case. Ask whether the organisation needs to improve:

• communication of policies and decisions;
• management consistency;
• standards of workplace behaviour;
• the way work or opportunities are allocated;
• record keeping;
• manager training;
• the way employees raise early concerns.

Even when a grievance is not upheld, it may reveal a communication, trust or management problem that deserves attention.

Managers who respond promptly, ask careful questions and explain their decisions clearly are more likely to prevent smaller concerns from becoming prolonged disputes.

Develop the Skills to Handle Workplace Grievances

Handling a grievance requires managers to remain calm, ask precise questions, evaluate evidence and distinguish facts from assumptions.

Our Investigation Skills Training gives managers a practical method for planning workplace investigations, interviewing the people involved and reaching evidence-based conclusions.

Where the main challenge involves difficult conversations, strong emotions or damaged working relationships, our Conflict Management Training develops the skills needed to manage disagreement and guide people towards a constructive outcome.

Good managers protect the fairness of the process. They define the allegation, test the evidence and explain their decision without taking sides prematurely.

This article provides general management guidance. Organisations should follow their own policies and obtain appropriate HR or legal advice where necessary.
