Aware of the impact of any organization on society, the Herald firm has for several years decided to invest in CSR by creating a dedicated commission. These commitments cover actions impacting both the internal functioning of the firm and the consideration of environmental issues.

At the end of 2016, in order to provide a more comprehensive response to the issues of corporate social responsibility, our firm decided to commit pro bono to two themes: the fight against exclusion and the promotion of equal opportunities. The firm is therefore committed to the Samu Social de Paris and the Institut Télémaque.

The Samu Social has a professional approach to the fight against extreme exclusion. It aims to provide assistance to homeless people at all times, day and night, and to seek the most appropriate responses.

The firm is committed to its work by offering free legal advice to families supported by the organisation. It also provides support in all areas of law for problems encountered by the Samu Social.

The Institut Télémaque intends to fight against academic and social determinism by supporting deserving and motivated young people from modest backgrounds from the 5th grade until they obtain their Baccalauréat, thanks to a tutoring principle: a company tutor and a pedagogical tutor.

Our teams work alongside the Télémaque Institute by sponsoring young people and providing them with regular extra-curricular follow-up.

In October 2019, the firm was awarded the Pro Bono Trophy “Team Prize” by the Paris Bar Association for all our actions.
