How Private Investigators Can Support Employee Investigations and Breach of Contract Cases

Managing a business always comes with challenges, but few situations are more difficult than dealing with suspected misconduct from a trusted employee. When allegations arise—whether it’s a potential breach of contract, false sickness claims, or working for a competitor during sick leave—it’s essential to handle the matter discreetly, professionally, and with concrete evidence. This is where the expertise of a private investigator becomes invaluable.

Case Study: An Employee Working Elsewhere Whilst Signed Off Sick

Please note: The following serves as an example of the type of jobs B25 Private Investigation undertakes on a regular basis. All cases handled by B25 remain strictly confidential; therefore names and details have been changed. 

Alex was a senior sales manager at a tech company in Bristol who had been signed off work for several weeks due to stress and anxiety. The business was sympathetic to his situation, and the HR manager ensured he was given the time and support needed to recover. However, partway through his 3-month leave period, another member of the team reached out to the company’s leadership, as they had heard that Alex was working with a direct competitor whilst being signed off sick.

Faced with the potential breach of his employment contract and the risk of confidential business information being shared, the company approached B25 Private Investigation for assistance.

How B25 Approached the Investigation

With discretion and professionalism, our experienced investigators conducted lawful surveillance to determine whether Alex was undertaking paid work elsewhere. Over the course of several days, our team gathered irrefutable evidence that confirmed Alex had accepted a consultancy role with a competing firm. This directly violated the terms of his employment contract, which included a non-compete clause and a duty of loyalty during his period of sick leave.

The evidence collected included:

  • Verified photographic and video documentation of Alex attending meetings at the competitor’s offices.
  • Time-stamped records detailing his working hours with the competitor.
  • Publicly available information confirms his temporary consultancy role.

In possession of this evidence, the employer was able to proceed with the appropriate legal and disciplinary action, protecting their business interests and maintaining contractual integrity. Without clear evidence, the situation could have remained unresolved, potentially leading to further financial and reputational damage.

Why Use a Private Investigator for Employee Investigations?

Cases like this require a careful, lawful approach. Employers must tread carefully to avoid accusations of harassment, wrongful dismissal, or data protection breaches. Engaging a professional, experienced private investigation team ensures that all information is gathered ethically, within the boundaries of the law, and is admissible should legal proceedings follow.

At B25, we understand the sensitive nature of these situations. Our highly trained investigators operate with complete discretion, using the latest surveillance techniques and technology to provide clear, unbiased evidence. Whether you suspect a breach of contract, false sickness claims, or conflicts of interest, we’re here to help you protect your business and make informed decisions based on facts—not assumptions.

What Types of Evidence Are Admissible in Breach of Contract Cases?

Gathering evidence is only part of the process. Ensuring that the evidence can be used legally and effectively is just as important. Here are the key types of evidence that are typically admissible in breach of contract cases:

1. Surveillance Footage
Video and photographic evidence can be highly persuasive, particularly when it clearly shows an employee engaged in activities that contradict their claims. Surveillance must be carried out in public places or where there is no expectation of privacy, and always in accordance with relevant privacy laws such as the Data Protection Act 2018.

2. Digital Evidence
Publicly available information on professional networking platforms, social media activity, and even job adverts or public company listings can be used to confirm employment status or business involvement. It is essential, however, that this information is gathered without resorting to deception or hacking, which would render the evidence inadmissible.

3. Witness Statements
Independent third-party witnesses who have directly observed the employee in question can provide valuable testimony. This could include individuals who saw the employee working at a competitor’s premises or engaging in activities inconsistent with their sick leave status.

4. Employment and Business Records
Records from Companies House or other business registration services may confirm that the employee has taken a formal role with another organisation. Similarly, consultancy agreements, invoices, or payment records—if lawfully obtained—can support the case.

5. Time-Stamped Documentation
Any evidence that includes verifiable timestamps—such as video footage, attendance records, or digital activity logs—can strengthen the case by clearly showing when and where events took place.

It’s critical to note that all evidence must be gathered in a lawful, proportionate, and ethical manner. Any breach of privacy or data protection regulations can not only render the evidence unusable but also expose the employer to legal action. That’s why working with a professional investigation agency like B25 is the safest and most effective approach.
