Last year the tech giant enhanced health care coverage by offering virtual doctor visits, second-opinion services, and breast-cancer screenings at headquarters. One Googler explained, “The company culture truly makes workers feel they’re valued and respected as a human being, not as a cog in a machine. The perks are phenomenal. From three prepared organic meals a day to unlimited snacks, artisanal coffee and tea to free personal-fitness classes, health clinics, on-site oil changes, haircuts, spa truck, bike-repair truck, nap pods, free on-site laundry rooms, and subsidized wash and fold.

The company has taken their employees snowmobiling and whitewater rafting, and celebrations are an integral part of Nugget’s culture, including everyday recognitions for jobs well done and multiple annual parties at stores.

The company has been a leader in providing benefits for same-sex couples and transgender employees, and has earned a 100% score on the Human Rights Campaign’s Corporate Equality Index for 11 consecutive years.

Their most spectacular donation has been $200 million for a new children’s hospital bearing their names. This social commitment is an extension of the company’s culture: Salesforce.com has logged over 1.3 million volunteer hours and donated more than $100 million in grants. Employees receive seven paid days a year to volunteer, and one employee told us: “We have the flexibility and support to volunteer on our own, yet be supported by the company.” To prove it, staff member donations are matched, dollar for dollar, by the company.

Location with the most employees: Los Angeles

Riot Games, maker of the popular video game League of Legends, welcomes new Rioters not with paperwork, but with “Denewbification”: an intensive immersion that starts with–what else?–a session of gaming. If new hires decide Riot’s not a fit before the end of their first 60 days, they will be offered up to 10% of their annual salary (up to $25,000) as an incentive to quit. As part of an open paid-time-off policy, the company places no limit on vacation or sick days spent outside of the office.
