Germany has been slower to instill gender diversity in the boardrooms of public and private entities than its EU counterparts, according to the Federal Statistical Office’s latest labor force survey. The region’s largest economy had only 29 percent of executive positions filled by women in 2014, little changed from the previous two years. This reflects the challenge facing companies scrambling to meet quotas that took effect on Jan. 1, with large corporations obliged to declare targets for executive boards while the government enforces a 30 percent quota for the supervisory boards that oversee them.
