Photonis France Professional Equality Index 2023

Declared a "great cause of the five-year period" by the Presidency of the French Republic, equality between women and men has been placed at the heart of government priorities. In this context, by decree n°2019-15 of 8 January 2019, a new system was defined, under the terms of which French companies with more than fifty employees evaluate themselves each year in the field of professional equality: the “Index Egalité Femmes Hommes”. Below a threshold of 75 out of 100 points, the company is required to define and implement corrective measures within three years.

Built around five indicators calculated on a total of 100 points, Photonis France SAS obtains a score of 86/100 for the year 2023.

  • The gender pay gap (38 points),
  • The distribution gap of individual increases (20 points),
  • The promotion distribution gap (15 points),
  • The number of employees increased upon their return from maternity leave (incalculable),
  • Parity among the top 10 highest salaries (0 points).

This great index is reflecting Photonis France policy in term of professional equality.

We are proud of this result, which is in line with our commitments. This great index reveals Photonis' values and actions on professional equality matter.
