If you want happy customers, start by making your employees happy. Aflac's award-winning corporate culture has landed it on FORTUNE Magazine's list of Best Companies to Work For sixteen years in a row, and a loyal workforce translates to the best possible service for 50 million people worldwide. For Aflac, that means integrating fun and camaraderie into the company's core values.

The Georgia-based insurer is among the most diverse Fortune 500 companies in the world, and offers competitive salaries, generous benefits, plentiful advancement opportunities, college scholarships and appreciation events culminating in an annual Employee Appreciation Week to thank the 4,600-plus workers for their dependability and expertise.

Aflac dedicates an entire week to celebrating employee achievements with events that are created by and for the employees themselves, from drawings for cash, stock and trips to various places to special luncheons for those who have achieved tenure milestones. Festivities include company-paid days at local attractions, and each employee receives an appreciation gift.

"It helps with the retention of our employees because they say, you know, this is the best company to work for," says Aflac's Brenda Mullins. "We want to let you know that we really appreciate everything that you do."
