Rank: 1. SAS

Its perks are epic: on-site healthcare, high quality childcare at $410 per month, summer camp for kids, car cleaning, a beauty salon, and more -- it’s all enough to make a state-of-the-art, 66,000-square-foot gym seem like nothing special by comparison.

This year, strong employee feedback sent its numbers even higher. Says one manager: "People stay at SAS in large part because they are happy, but to dig a little deeper, I would argue that people don’t leave SAS because they feel regarded -- seen, attended to and cared for. I have stayed for that reason, and love what I do for that reason."
