Not when quotas are involved. In Germany, where I live, every few years serious attempts to introduce women quota for companies are attempted to pass as a law (which typically are only prevented in the last moment because of massive protests of business associations).
Since Januar 2016 gender quotas for the supervisory council of the 106 largest market-listed companies were introduced. For restaffing in the supervisory council there is a quota of 30% for both gender (or the position has to be left vacant).
