Forbes partnered with market research firm Statista to survey 70,000 workers at companies (minimum of 500 employees) in all 50 states and the District of Columbia. Participants were asked if they would recommend their employer to others, and to evaluate their employer based on working conditions, diversity, compensation packages, potential for development, company image and more.

Participants were also asked to assess employers beyond their own: Respondents could evaluate employers in their particular state; nationally, participants were able to rate employers anywhere within their respective industries. All surveys were anonymous to encourage candor.

Several NC Heath Systems and Hospitals ranked high on the list: WakeMed ranked #4, UNC Health Care ranked #7, Duke University Health System ranked #14, Novant Health ranked #38, and Cone Health ranked #39.
