Alerion, aware of the need for local beekeepers, is committed to the preservation of the ecosystem by sponsoring a beehive in the Paris region thanks to the association Un toit pour les abeilles.
The firm has also implemented several practices within the firm:
- Providing our team with recycled paper.
- Using an external service provider to collect used paper and recycle it.
- Paper consumption has been significantly reduced thanks to the successive lockdown that have accelerated the digitalisation of processes and we didn’t go back to the way it was before.
- Thanks to a partnership with Le Cercle, the meal trays are environmentally friendly. Indeed, Le Cercle recovers the meal trays to reuse them, all in order to be part of a more eco-responsible approach.
- The firm distributes mugs to its team members to encourage them to stop using single-use cups and bottles.
- The Christmas tree is originated from France and horticulturally grown.
The firm’s approach to society
Alerion acts for its co-workers’ well-being at work:
- The firm carried out sessions on the prevention of work-related illnesses by videoconferencing with an external service provider.
- Following the coronavirus crisis, a remote working policy was established.
- A fruit basket is available to employees twice a week in the office.
- The firm has a fair gender ratio : we have 50.6% women and 49.4% men as of 2021.
- Career and development opportunities are encouraged. Since its creation, Alerion has seen seven associates become partners and continues to see its associates evolve within the teams.
- In addition, a quality commission is held every two months to discuss and improve well-being within the firm.
