Aflac, the leading provider of voluntary insurance at the worksite in the United States, announced it ranked No. 5 on FORTUNE magazine's list of the Best Workplaces in the Fortune 500. One of only 16 Fortune 500 companies to appear on Fortune's 100 Best Places to Work list in 2016, the company, which has 18 consecutive appearances on that list, was compared to other companies in the Fortune 500 in a recent article published at Fortune.com.

"This ranking is a tribute to our founding principle that says if you treat employees right, they will take care of the business," Aflac Chairman and CEO Dan Amos said. "It validates the notion that being a company that exercises ethical and employee-friendly practices will have a strong impact on the bottom line. In today's environment, how you do business is as important to consumers and investors as the products you produce."

The employee survey is conducted annually by the Great Place to Work Institute on behalf of FORTUNE magazine, and the review is based on 1,134 employee surveys with 96 percent confidence level and a margin of error of plus or minus 2.58 percentage points.

"We are a business that sells a promise to our customers that if they trust us to protect their financial security, we will be there for them in their times of need," Amos said. "The first step toward fulfilling this promise is to ensure our employees believe in the company. I am pleased that these results demonstrate content workers who are proud to consider themselves part of the Aflac family."
