A new panorama, the result of a partnership between the RÉUNIS endowment fund and the Sustainability & Organizations (S&O) Centre at HEC Paris, highlights 50 innovative practices for strengthening social cohesion within companies.

Facing the challenges of hybrid work, artificial intelligence, and societal changes, the company remains a key place for developing collective bonds. This report, the outcome of six months of work and based on the analysis of over 165 practices identified in France, aims to provide leaders and managers with a concrete tool for building stronger teams.
Presented on October 14th at the Galerie du 19M, the panorama was introduced by Aline Gatignon, strategy professor at HEC Paris, and Mathieu Noguès. The launch was led by Arnaud Gangloff, president of RÉUNIS, and Florence Casalis, its general director.
A round table discussion then brought together representatives from founding companies such as Emmanuelle Greth (Galeries Lafayette), Sébastien Lebreton (CHANEL Mode), Frédéric Levacher (Quick), and Sabrina Herlory Rouget (Aroma-Zone), who shared their experiences and strategies for strengthening the collective.
The study, which surveyed fifteen companies and conducted forty interviews, does not merely share inspiring examples. It seeks to understand the underlying mechanisms that make these initiatives effective, enabling other organizations to adopt them. Aline Gatignon emphasizes that trust, interpersonal relationships, and a sense of belonging are crucial, and that diversity must be leveraged as a strength.
The panorama proposes a three-level approach: decision-making and embodiment by leaders, organization of collective work by managers, and support for individual transitions. The goal is to provide concrete means to enhance social cohesion and, consequently, the sustainable performance of the company.
This collaborative project, bridging academic research and field experimentation, involved Florence Casalis, Marieke Huysentruyt, Mathieu Noguès, and Quitterie D'Everlange. It highlights the idea that the general interest is played out at the heart of the company.
