Our Culture Famous for Our Culture Our culture begins and ends with our employees. We are a celebratory, inclusive, magenta-loving team of people united in our commitment to change our industry for the better. Due to the pandemic and political and social unrest, the last two years have been difficult for people and companies everywhere. T-Mobile is no exception as we prioritized the health and safety of our employees while simultaneously integrating two companies into one unified culture. But if there is one constant that stayed true, it’s that Team Magenta is resilient, strong, proud, and unwavering in our commitment to our customers and to one another. And that’s why we have been so focused on getting it right. We are one team, together. The Future Is Magenta Our culture is something we never take for granted. It’s what unifies us in our mission to be the best in the world at connecting customers to their world, and what motivates us each and every day to be a part of something bigger. We work hard to stay connected to Team Magenta and have a variety of tools and forums to do that. One of the most important ways that we measure the health of our culture is through our confidential Our Voice surveys, which go out multiple times each year to all employees. The survey helps us to gauge how employees feel about our company, what they love about their jobs and what they don’t. It’s a big part of how we continue to evolve and grow. In October 2021, approximately 39,000 employees took the survey and relayed the following sentiment: ■ 87% of employees say their team clearly prioritizes the customer experience in its work ■ 86% of employees say their own team creates an inclusive work environment “for me to be myself” ■ 80% of employees would recommend T-Mobile as a great place to work AN AWARD-WINNING PLACE TO WORK T-Mobile has once again been recognized as a great place to work by leading national workplace awards and surveys. The following 2021 rankings are based on survey responses from the real experts: our employees. ■ America’s Best Employers list by Forbes ■ Comparably’s Best Global Culture list ■ Fortune 100 Best Companies to Work For ■ Glassdoor’s Best Places to Work list We attribute our success to our unique culture and values. They’ve ensured we’ve grown closer through challenging times and success alike—and they’ll guide us through an exciting new era of Un-carrier, too. Employee Forums In addition to Our Voice surveys and roundtable discussions with our directors and VP’s, our CEO and leadership team hosts quarterly All-Employee Meetings where they share the latest company news, celebrate wins, and discuss challenges ahead. These always feature an open Q&A session, the highest rated portion of the meeting, where everyone has a chance to engage on what’s top of mind. Past All-Employee Meetings have included a discussion of new service offerings, how the company is navigating the pandemic, and how—through our values—we can have a bigger, better, and more meaningful impact together. Building and maintaining a culture we can be famous for requires care and commitment. It’s something we take seriously and is work that’s constantly evolving.
