EY, Kaiser Permanente, Novartis, PwC and Sodexo have been inducted into our first-ever Top 50 Hall of Fame. The companies have ranked number one on our list, at least once since 2012. In order to maintain Hall of Fame status, companies will be re-evaluated annually in the Top 50 competition and remain Top 10 competitive. Hall of Fame companies will be listed above the Top 50 on our website. Future number one companies will be added to the Hall of Fame.
