Defamation in the workplace: how to prove it?

Defamation in the workplace refers to any false statement that damages the reputation of an employee or employer. In a professional context, it can seriously undermine trust, tarnish an image built up over many years and jeopardise a career. The impact often results in lost opportunities, damaged professional relationships and social isolation. In the UK, the Defamation Act 2013 regulates this area by requiring proof of ‘serious harm’ to reputation before any legal action can be taken. Consulting lawyers specialising in defamation provides strategic support in assessing the strength of a claim and effectively defending one’s professional reputation.

What is defamation at work?

Defamation in the workplace refers to any false statement communicated to one or more people that causes harm to the reputation of an employee or employer. It goes beyond a simple conflict between colleagues, as it directly affects professional credibility and standing within the work environment.

Libel and slander aretwo forms of defamation common in the workplace:

• Libel: written or published defamation (internal emails, reports, posts on social media).
• Slander: spoken defamation, often in the form of rumours, comments made during meetings, or informal conversations.

Specific features in the workplace

In the workplace, the spread of defamatory information is particularly damaging: a single email or a persistent rumour can quickly circulate, undermine trust, disrupt collaboration, or block career progression.

The notion of “serious harm”

Under the UK Defamation Act 2013, a legal action is only admissible if the claimant can demonstrate serious harm to their reputation. This means proving that the statements have led to a real and significant deterioration of their professional image, relationships, or career prospects.

What are the common examples of defamation at work?

Defamation in the workplace can take many forms, ranging from simple rumours to written statements with lasting impact. Below are some common examples that show how it can occur in everyday work life:

Rumours between colleagues

Rumours are one of the most widespread forms of slander. They can concern an employee’s competence, personal life, or loyalty to the company. Even if unfounded, such statements damage reputation and undermine trust within teams.

Emails and internal messages

Written communications, including emails, Slack, Teams, or other collaborative tools, fall under libel. A defamatory remark circulated in writing can be preserved, shared, and later used as evidence in a claim.

Public posts on social media

When an employee publishes defamatory content on LinkedIn, Facebook, or X (Twitter), the statements take on a public dimension. The impact on professional reputation can then extend beyond the office and affect the individual’s standing in their entire sector.

Cases linked to harassment or discrimination

Defamation is sometimes used as a tool of harassment: false accusations aimed at discrediting a colleague, or defamatory comments based on gender, ethnicity, or religion. These situations not only harm reputation but also create a toxic work environment.

What is the UK legislation covering defamation at work?

In the UK, workplace defamation is primarily governed by the Defamation Act 2013. This law sets out the conditions that an employee or employer must meet to bring a claim in court.

Conditions for making a claim

For legal action to be admissible, the claimant must show that:

• The statement is false,
• Was communicated to a third party,
• Has caused serious harm to their reputation in the workplace or publicly.

Serious harm means that the defamatory statement has had a real and significant impact on the individual’s reputation. This could include a loss of trust among colleagues, damage to professional standing within the company, or broader consequences if the statement is made public, for example via social media or the press. The law requires more than minor inconvenience; the person’s reputation must be notably damaged, potentially affecting their career, professional relationships, or credibility in their sector.

Possible legal defences

Certain protections exist for authors of allegedly defamatory statements:

• Truth: if the statement is verifiable and accurate, it is not considered defamatory. This means that if the reported facts can be proven and reflect reality, the author cannot be held liable.
• Honest opinion: a critique expressed objectively and based on known facts. Even if the opinion is negative, as long as it relies on verifiable elements and does not present false statements as facts, it is legally protected.
• Public interest: this defence applies when the statement aims to inform or protect the public. If the remarks concern important societal issues, safety, or transparency, the author can argue that they were acting in the general interest.

Specific considerations in the workplace

Within a work context, it is often advisable to attempt internal resolution through HR before pursuing legal action. However, serious situations, such as public dissemination or harassment involving defamatory statements, may require direct legal action to safeguard one’s reputation.

What evidence and elements are needed to make a workplace defamation claim?

To bring a defamation claim in the workplace, it is necessary to show clearly how the statements affected professional reputation and working relationships.

Types of evidence to collect:

• Emails, internal messages, and screenshots: any written communication within the company or via collaboration tools can be used as evidence.
• Colleague or third-party testimony: individuals who heard or witnessed the statements can confirm their existence and impact.
• Official documents: internal reports, performance reviews, or notes showing the consequences for career progression or professional perception.

Demonstrating the impact on reputation

It is important to show that the statements had a real effect on the employee’s reputation, for example:

• Loss of trust from colleagues or management,
• Reduction of professional opportunities or career stagnation,
• Social or professional isolation, or deteriorating relationships within teams.

Other elements that can strengthen a claim:

• Dates and context: note exactly when and under what circumstances the statements were made.
• Repetition and circulation: statements repeated or shared with multiple people reinforce the claim.
• Employer response: whether the company attempted to address the issue or failed to react can also be considered.

Collecting these elements helps build a solid case and demonstrate the tangible effect on reputation in the workplace.

How does a defamation procedure at work unfold in the UK?

When an employee is the victim of defamation, the UK legal system provides a framework to protect their reputation and seek redress.

Internal resolution before legal action

Before taking the matter to court, it is common to try to resolve the issue internally. This can include:

• Mediation between the parties to clarify the facts and ease the conflict,
• Involvement of Human Resources or management to investigate the statements and take corrective measures,
• Sending a letter before action to inform the person responsible and request a retraction, apology, or correction.

Taking the claim to court

If internal measures are insufficient, the claim can be brought before the civil courts:

• Official filing of the claim: the document sets out the facts, evidence, and harm suffered.
• Presentation of evidence: emails, messages, screenshots, testimonies, and internal documents demonstrating the impact on reputation.
• Legal representation: the employee is assisted by an employment lawyer to argue the damage caused and respond to any defences from the person responsible.

Timelines and costs

The duration of the process varies depending on the complexity of the case and the court’s schedule. Legal costs can be significant, though some insurance policies or agreements with the employer may cover part of the expenses.

The process aims to restore the employee’s reputation, hold the person responsible for defamatory statements accountable, and encourage resolution of the conflict, while following the legal steps outlined in the Defamation Act 2013.
