Google needs to do more to boost diversity in its workforce, according to the company's latest annual report on the tech giant's makeup. "The data in this report shows that despite significant effort, and some pockets of success, we need to do more to achieve our desired diversity and inclusion outcomes," explained Danielle Brown, Google's chief diversity and inclusion officer, in a statement on the report. Specifically, the report found that attrition rates for black Google employees, while improving in recent years, have offset some of the company's hiring gains. "We're working hard to better understand what drives higher attrition and taking focused measures to improve it," said Brown.
