The bill for the freedom to choose one's professional futur promulgated on September 5, 2018 created a new obligation in companies with more than 50 employees to calculate and publish a professional equality index aimed at measuring the gaps between women and men in the professional environment.

This index is calculated on 100 points based on 5 indicators defined by law.

Each company concerned must obtain an overall score of 75 points; below this, corrective measures must be put in place to reduce or even eliminate the observed gaps.
