Atlassian

Every quarter, Atlassian's employees are given 24 hours to work on a project of their choice as long as it relates to the company's products, office, or culture. Though it culminates in a contest with winners for the best ideas, the maker of workplace collaboration software knows how to rewards all of its employees all year long. Atlassian employees enjoy paid volunteer time and unlimited vacation, along with tasty meals and snacks every day. Read the Great Place to Work review here.
