Sick Leave Fraud Investigation
Long-term sick leave costs an employer thousands of euros per month. But what if you have the feeling that something does not add up? Perhaps you see social media activity that does not match the complaints. Or colleagues report that the employee is active elsewhere. A sick leave investigation gives you the facts. No assumptions, no suspicions — but concrete, verifiable evidence you can act on legally.
What we investigate
What does a sick leave investigation deliver?
The result is a clear report with our findings, built from multiple sources: Observation — we monitor the employee's activities over a defined period, including visits to gyms, DIY activities, or work elsewhere. Digital investigation — open sources, social media activities, and relevant online signals are analysed. Reporting — you receive a factual, substantiated report that is usable in employment law proceedings or consultations with the occupational doctor. We work exclusively within the boundaries of the Dutch Private Security and Investigation Agencies Act (Wpbr) and the GDPR. This means the evidence holds up where it matters.
In which situations do employers engage us?
An employee reports long-term sick leave but is spotted performing physical activities. Suspicion of undeclared work during a sick period. The occupational doctor has doubts but lacks sufficient insight into the factual situation. Reintegration obligations are not being met. You are considering dismissal but lack the necessary case file.
