Moral or sexual harassment in the workplace is a difficult reality to deal with… and even harder to prove. In Paris, whether you’re an employee who’s been victimized, an employer facing a volatile situation, or an HR director who needs to take action, the question is often the same: how can you gather solid evidence before taking action? This is precisely where a private investigator comes in. Aquila Stratégie assists companies and individuals with discreet, professional investigations conducted in strict compliance with the law.
Workplace Harassment in Paris: How to Gather Evidence with a Private Investigator

Workplace Harassment: An Underestimated Problem in Paris
The intense and competitive Parisian workplace is not immune to harassment. There are two main forms:
- Moral harassment: repeated behaviors that undermine an employee’s working conditions (humiliation, isolation, deliberate overburdening, belittling, etc.).
- Sexual harassment: remarks or behavior of a sexual nature that are repeatedly imposed on someone.
In both cases, the main challenge is the same: the events often take place behind closed doors, without direct witnesses, or in a context where witnesses are reluctant to speak out. Testimony alone, without factual evidence, is generally not enough to initiate legal proceedings.
Why hire a private investigator before contacting HR or the labor court?
Before initiating formal proceedings—filing a complaint, reporting the matter to HR, or bringing a case before the Paris Labor Court —it is essential to have concrete evidence. That is why more and more employees and employers are choosing to engage a private investigator early on.
Here’s what an investigation actually reveals:
- A record of the facts: dates, locations, frequency of the behaviors, and context.
- A collection of testimonies compiled in accordance with best practices, which protects the witnesses.
- A structured investigative report, prepared by licensed professionals, that can be used in an HR or legal case.
- A neutral and objective approach that lends credibility to your case before decision-makers or a judge.
The detective does not replace the lawyer or HR. He provides them with the raw material they need to act effectively. It is a complementary relationship, not a competitive one.
What the Aquila Group Actually Does in a Harassment Investigation
Our investigators work methodically and discreetly, tailoring each assignment to the specific context:
Preliminary Review of the Case File
Our investigators work methodically and discreetly, tailoring each assignment to the specific context: During an initial confidential consultation, we assess the situation with you—the nature of the facts, the individuals involved, the work environment, and any information you already have. No investigation is launched without a clear understanding of your needs.
Information Gathering and Surveillance
Depending on the situation, our detectives can conduct field surveillance, identify recurring patterns of behavior, cross-reference information from open sources, or establish a precise timeline of events.
Interviews and Testimonials
Our investigators are trained to take statements from colleagues or potential witnesses, while respecting their anonymity when necessary, and in accordance with the legal safeguards that ensure this information is admissible.
Submission of the Investigation Report
At the conclusion of the assignment, you will receive a detailed report that is dated, signed, and compliant with the standards of the CNAPS. This document can be forwarded to your attorney, HR management, or the court if necessary.
Employers: Why Should You Act Quickly When a Report Is Filed?
From a business perspective, a reported case of harassment that is mishandled can have serious consequences: labor disputes, damage to the company’s reputation, and disruption of teams. Employers have a legal obligation to protect their employees.
Hiring a private investigator in this situation means:
- Maintain control of the situation without launching a haphazard internal investigation.
- Gather objective information before making an HR or disciplinary decision.
- Protecting yourself in the event that the company’s liability is called into question.
In Paris, where there are many companies and labor disputes are common, this precaution can make a real difference.
