“Western Digital is honored to be among 135 companies recognized for setting global standards of business integrity and corporate citizenship,” said Tiffany Scurry, Western Digital’s chief compliance officer. “At Western Digital, how we do our work is just as important as the results we achieve. Our Global Code of Conduct guides how we develop and deliver products, and how we work with customers, suppliers, distributors, and other partners. Operating responsibly and ethically isn’t just the right thing to do; it’s a key marketplace differentiator.”

In addition to Ethisphere assessing data responsive to more than 200 questions on a company’s culture, environmental, ethics and diversity initiatives, this year’s process also evaluated how applicants were adapting and responding to the global health pandemic, environmental, social and governance factors, as well as safety, equity, inclusion and social justice.

“While addressing the tough challenges of 2020, we saw the World’s Most Ethical Companies honorees continue to demonstrate an unwavering commitment to the highest values and positively impact the communities they serve,” said Ethisphere CEO, Timothy Erblich. “Congratulations to everyone at Western Digital for once again earning the World’s Most Ethical Companies designation.”
