Suspect fraudulent sick leave within your company? Our specialized investigators have more than 25 years of experience in sickness absence investigations and have successfully resolved hundreds of cases of employee fraud.
False sick leave can cause serious financial damage to organizations. Our professional investigations help employers obtain clear, legally valid evidence when an employee falsely reports sick.
When fraudulent sick leave is proven, the employment contract can often be terminated immediately for urgent cause. In many cases, the costs of the investigation can also be recovered from the employee involved.
Professional Sick Leave Investigation
Our corporate investigators observe the employee who reported sick over a period of four to eight regular working days.
When activities are identified on four separate days that contradict the reported illness, this legally qualifies as fraudulent sick leave and provides a strong legal basis for dismissal.
If conflicting activities are not observed every day, the investigation may be extended to six or eight days to obtain sufficient evidence. On average, a sickness absence investigation takes six days.
Our goal is to gather clear, reliable, and court-admissible evidence.
Legally Valid Evidence for Employers
Our investigation agency is recognized by the Ministry of Justice and Security. This means that the observations made by our investigators are admissible as evidence in court.
During the investigation, conflicting activities are documented and recorded on video to ensure the evidence is clear and indisputable.
As an additional service — free of charge — we can confront the investigated employee with the collected evidence after the investigation. In many cases this results in a written confession, which strengthens the evidence and often makes legal proceedings unnecessary. This can save employers significant legal costs and time.
Fraudulent Sick Leave with Physical Complaints
Our investigations have repeatedly shown that employees who reported sick with serious physical complaints — such as a herniated disc, knee injury, or neck problems — were observed performing physically demanding activities.
Examples include employees who were filmed:
• Training with heavy weights in the gym • Practicing martial arts or intensive sports • Performing construction work • Installing fences, paving stones, or roofing
In some cases, employees on sick leave were even found working for themselves or for a competitor.
Burnout or Mental Health Sick Leave Fraud
Employees sometimes report sick due to alleged burnout or mental health complaints, claiming they are unable to perform any activities.
However, many activities can contradict such claims. For example:
• Driving a car • Practicing sports • Running a business • Performing construction or repair work
Our sickness absence investigations have uncovered employees who, while claiming burnout, were running their own company, repairing boats or roofs, or even building their own homes.
In many of these cases, the result was immediate dismissal.
