OUR COMPANY OUR GOVERNANCE OUR PEOPLE OUR COMMUNITIES THE ENVIRONMENT THE NUMBERS AND SMALL PRINT Health, Safety, and Wellness Continued Removing Barriers T-Mobile is committed to removing barriers for employees to access our benefits whenever possible. For example, we pay tuition expenses up front for employees wishing to further their education, making it easier to attend school on a part-time basis by not having to worry about fronting out-of-pocket costs. It’s also why we’re constantly evolving current benefits to better meet the needs of our employee base. ~$20.2M paid in tuition assistance for more than 5,500 employees In January 2022, we enhanced our employee assistance program even further to ensure the clinicians taking calls better represent the demographics of ALL of our employees. COMPANY OWNERSHIP CREATES A DIFFERENT MINDSET Every member of our team is given the opportunity to be an owner of the company. Since 2014, we have awarded annual restricted stock unit grants to eligible employees at every level of the company so that everyone can truly share in T-Mobile’s performance. We also offer an employee stock purchase program, where employees can purchase TMUS stock at a 15% discount through payroll deduction. Rethinking a Renovation in Real Time 2021 CORPORATE RESPONSIBILITY REPORT 39 When COVID-19 began sweeping the world, T-Mobile had to pivot its ambitious renovation plans for our headquarters in Bellevue, WA and Overland Park, KS to incorporate the enhanced safety measures we knew would become commonplace in a post-pandemic world. Darcey Estes, Vice President, Corporate Real Estate, and her team got to work searching for ways to mesh her goal of creating inspiring spaces with a heightened emphasis on creating the safest environments possible during a pandemic. Heating, ventilation and air-conditioning (HVAC) systems were upgraded to maximize filtration in all buildings and MERV 13 filters were installed in all buildings (where mechanically feasible). Incredible new co-working spaces, high-tech conference rooms, creative social spaces, and top-of-the line amenities were enhanced to integrate COVID-19 health and safety features like social distancing signage, capacity limits, sanitation stations, and contactless building features. Not only did Estes’ team pivot mid- stride to rethink headquarter office renovations, they also worked to get all regional corporate office locations and 24 customer experience centers, in addition to the Bellevue and Overland Park headquarters, certified through the WELL Health-Safety rating, a first for our industry. The rating was created by the International WELL Building Institute, the global authority on healthy buildings, and incorporates guidance from more than 600 public health experts from around the world. Estes says, “Since the very early days of the pandemic, T-Mobile has been focused on doing everything we can to ensure our customers and employees feel healthy and supported when they step into any of our spaces, and this WELL Health-Safety rating reflects our immense dedication to those efforts.” Thanks to this work, T-Mobile spaces are both inspiring and safe, reflecting our commitment to employee and customer health and safety. It’s just one more reason why T-Mobile is a great place to work.
