Your need is legitimate, trust the experts
Whether civil servants or contractual agents, it is strictly prohibited for any public agent to hold multiple employments. A public agent is required to dedicate themselves exclusively to the tasks and missions assigned to them, and solely within the scope of their duties.
Nevertheless, even if it is conceivable to combine a position in the public service with other commitments, this practice is subject to strict regulations and close monitoring.
Groupe Hyperion positions itself as the preferred contact for employers wishing to uncover this type of unauthorized employment by one of their agents, which undermines public service rules, as well as productivity and workplace safety.
Our experts are fully aware of the legal realities, obligations, and procedures to implement to quickly and effectively resolve the ongoing dispute with your agent.
Services provided by Groupe Hyperion
Surveillance and Shadowing
We initiate our investigations with surveillance to observe the activities of the suspected agent. This includes collecting visual and audio evidence, such as photographs and videos, to document the suspect’s actions outside their official working hours. These observations help confirm or refute suspicions of multiple employments.
Information Verification
We cross-reference the collected data with available official information, including declared working hours and places of employment. This verification helps highlight any inconsistencies or violations of the agent’s professional obligations.
Investigation Report
At the conclusion of our investigation, we compile a detailed report including all collected evidence. This report, comprising photos, videos, and testimonies, is structured to be admissible before administrative and judicial authorities, thus guaranteeing the legitimacy of our findings.
Compliance with Legislation
Throughout our investigations, we ensure that we do not infringe upon the agent’s privacy, in accordance with administrative court rulings. Our methods strictly adhere to the code of ethics and current legal provisions, ensuring that the evidence obtained is legal and admissible.
