Google

For the sixth year running, Google has landed the top spot on our list of the country’s Best Companies to Work For. The $75 billion tech titan is famous for luxe perks like free gourmet food, haircuts, and laundry services, of course. But it also takes a ­rigorous analytical approach to morale. It boosted its parental-leave policies, for example, after finding that mothers were leaving at higher rates—the result was a 50% reduction in attrition for working moms. And then there’s the culture: Town halls held by black Googlers and allies, support for transgender workers, and unconscious-bias workshops (­already attended by more than 70% of staff) help foster what employees say is a “safe and inclusive” workplace at this hive of high performers.
