The fines came after French Women's Rights Minister Najat Vallaud-Belkacem Thursday vowed to crack down on companies that failed to pay men and women equal salaries, Radio France Internationale reported.
Both of the companies had been warned previously they could face repercussions if they did not improve pay equality. One of the companies will be fined $6,511 every month until it has conformed to legal equal-pay requirements, and the other was given a one-time fine of $11,069 for not providing required documentation.
In France, women in the private sector earn about 28 percent less than their male counterparts, RFI said.
Noam Leandri, president of the French Observatory of Inequalities, said the discrepancy is due to the fact that more women work part time and take maternity leave.
