From The New York Times :
France and other countries with legally binding quotas have made the most progress in placing women in top business positions, Ms. Reding said during an interview Friday in advance of her announcement. E.U.-wide rules were now needed, she said.
“Personally, I don’t like quotas,” Ms. Reding said. “But I like what the quotas do. Quotas open the way to equality and they break through the glass ceiling.” Countries that have quotas “bring the results,” she said.
