1. Hilton

"Hilton has launched an expansive program to upgrade 'back-of-house' areas used by staff to make them as spiffy as the areas guests use," Fortune writes.

According to the Great Place to Work Institute, Hilton outperforms when it comes to satisfaction among typically more disenfranchised 'line-level' workers, such as cleaning and kitchen staff."
