AT&T is one of the 2017 Fortune 100 Best Companies to Work For, according to global research and consulting firm Great Place to Work® and Fortune.

It’s the first time AT&T made the list, which is based on employee ratings of their workplace culture, including the level of trust they feel towards leaders, the pride they take in their jobs and the camaraderie they experience with co-workers. The company was recognized for its commitment to diversity and inclusion, its dedication to training and development for employees, its focus on philanthropy, and its nurturing culture, among other things.

This year marks the 20th anniversary of the Fortune 100 Best Companies to Work For list, and 2017 winners continue to show that a high-trust culture fuels better business results. Great Place to Work research shows that list winners keep outperforming the stock market, beating industry rivals when it comes to talent retention and demonstrating higher levels of productivity than peers.

“We get a lot of awards, but to be named one of the best places to work is especially gratifying because it recognizes that our employees are engaged, excelling and enjoying what they do,” said AT&T Chairman and Chief Executive Officer Randall Stephenson. “All the investments in our people – from compensation and benefits, to diversity and inclusion programs, to the tools we provide for learning new skills – have created an environment in which our employees can grow and succeed. And that pays off in how they serve our customers and support one another.”

“Congratulations to the 2017 100 Best,” said Michael C. Bush, CEO of Great Place to Work. “These leading companies are at the vanguard of a new business frontier, where organizations know they have to develop the full human potential of all their employees. They are working to build Great Places to Work For All, which are better for business, better for people and better for the world.”
