A L&E department led by 2 complementary high-profiled partners

Pierre-Jacques provides best practice recommendations and strategical view and shares his experience with the team to strengthen our practice and optimize the defense for the best interests of our clients.

Stanislas Dublineau holds a PhD in private law. As such, he has a strong network with the main labor & employment law Professors at the top French Universities. Stanislas is thus associated to all reflexions and brainstorming on French new laws. Thanks to this network, the team benefits from very high-end expertise.

Sharing knowledge is important for each of our partners, within the team and also with law students. This is why both partners dedicate part of their working time to teach labor and employment law in business or ingeniary schools (HEC Paris and Central Supélec).

The team shares a very strong team and also entrepreneurial spirits and works with the upmost integrity. Our strength: we understood that working closely and collectively is the key asset for serving our clients at their best interests and with their full trust.
