Today, women represent more than 50% of the world's population, yet in no country do they represent nearly half of the corporate managers. According to the United Nation's fourth Conference on Women, women hold only 14% of the top managerial positions in business and only 10% of national legislative seats. Barriers to women's entry into senior management, otherwise known as the "glass ceiling", exist across the globe, and in some areas of the world it is worse than in others. Despite recent progress in most countries, women's advancement in the business arena has been slow. As we are into the 21st century, companies will need to increasingly reflect diversity in their workforce and management can no longer afford to ignore the positive impact women can make.
