Services provided by the Hyperion Group
Sick leave
Monitoring an employee on sick leave is a delicate mission, requiring a discreet and professional approach. Our agents are trained to collect evidence in a legal and ethical manner, in order to verify that the employee is complying with the conditions of his sick leave.
Work accident
When an employee is off work as a result of a work-related accident, it's crucial to ensure that the conditions of the stoppage are respected. Our investigators can check that the employee is not engaging in activities contrary to the medical restrictions imposed.
Repeated or suspicious absences
An employee's repeated or suspicious absences may be a sign of deeper problems within the company. Our teams are empowered to conduct investigations to determine the real reasons for such absences. This may include checks on the employee's schedule, interviews with colleagues and analysis of the reasons for absence declared by the employee.
Professional obligations
It is essential to ensure that employees comply with their professional obligations during working hours. Our investigators can discreetly observe an employee's activities during working hours to ensure that they are fulfilling their duties properly and not engaging in behavior detrimental to the company, such as theft, industrial espionage or misuse of corporate assets.
