While many corporations strive to foster inclusiveness and diversity in workplaces, historically, the more frank discussions around those issues have often been deemed too sensitive for the professional environment.

That reality wasn't lost on Tim Ryan, the U.S. chairman of PricewaterhouseCoopers. And it was a desire to drive legitimate change in that respect that led to him founding a new initiative called CEO Action for Diversity and Inclusion, a pledge signed by 175 CEOs — including our own CEO Oscar Munoz — from more than 50 industries in the U.S.

The CEOs who have chosen to participate do so with the promise that they will encourage open, candid conversation within their respective organizations on the subjects of race, gender, sexual orientation, disability and veteran status.

"A culture of diversity doesn't end at a person's hiring; that should mark the beginning of an ongoing and open conversation," Oscar said. "However, in my own experience, while there's a lot of talk about the importance of hiring diverse candidates, too many people find that actually talking about the issues they see in corporate culture is very difficult, if not outright discouraged. As one of the few Latino CEOs of a Fortune 500 company, I think it is so important that everyone feels free to be who they are and say what they think – even when it may touch on complicated issues – in a respectful, thoughtful way in the workplace. I applaud this initiative because a truly diverse culture cannot be achieved through lip service; only through sustained and vibrant dialogue."
