2021 Owens Corning Sustainability Report | Expanding Our Social Handprint | Health & Wellness | 269 HEALTH & WELLNESS INITIATIVES COVID-19 and Owens Corning Although there were promising developments throughout 2021, it is clear that the COVID-19 pandemic will remain a concern for some time to come. It continues to affect our operations around the world, and we continue to review and update a range of strategies that were initially implemented last year. Updates to these strategies are made to reflect current guidance from health organizations, as well as local mandates and recommendations. Our EHS and HR teams have taken the lead in tracking occurrences of COVID-19. Champion Network Owens Corning’s Champion Network consists of individuals at our facilities who work to ensure that our Healthy Living platform is locally driven with broad corporate support. Wellness champions are always looking for ways to engage employees about their health and increase participation in our programs. These champions are also able to encourage more individuals to join the champion network, expanding our influence at more locations. We have invested significantly in training local wellness teams and Healthy Living champions to help support our programs. In 2021, we trained 24 new wellness champions, and we now have wellness teams in the U.S., Canada, Latin America, Europe, and Asia Pacific. We also worked with our regional wellness leads to establish a network of 39 international champions. With the pandemic, we’ve performed extensive virtual training with the international groups. This training includes the principles of TPM, and we have the support of regional TPM leaders, who are helping to drive this work. Our sites in different countries and regions adopt their own healthy living goals and aspirations, so activities and focus areas are aligned with our employees’ needs and realities. We created teams that include leaders from global business and corporate function groups, as well as regional leadership councils, to direct the execution of our global wellness strategy in each region. Wellness champions have had the most impact when they have the support of leadership, and that engagement has been a core part of our overall approach to health and wellness. Materials to support activities planned for each pillar are available to champion teams so they can successfully engage employees and teams. Flu Shots While COVID-19 remains at the forefront of people’s health concerns this year, we still needed to contend with the influenza outbreaks that crop up each autumn and winter. Owens Corning has continued to stress the importance of flu shots as a way to help prevent the spread of the disease, and we remind employees that most Owens Corning sites around the world offer flu vaccines. Given the differences in healthcare distribution in different countries around the world, flu shot campaigns are organized locally throughout our regions. Fatigue Risk Management In 2018, Owens Corning began work on strategies to improve supervisors’ and managers’ awareness of and responsiveness to fatigue-related problems. Through this training, we also seek to create a work climate that supports health management of energy, sleep, and focus at work. To achieve this, we developed an innovative leadership training, Energy & Focus (E&F), and a new Owens Corning standard for fatigue risk management. E&F training covers topics associated with healthy lifestyle decisions related to sleep and fatigue, the basics of fatigue-risk management within plants, and accessing resources to reduce safety risks associated with fatigue. The training was developed using significant input from managers and focus groups, making the training unique to Owens Corning. Following a pause in 2020 due to COVID-19 restrictions, work picked back up in 2021 with programs at select sites in the U.S. and Europe. We are also developing dashboards that will enable site leadership to identify work hour trends and early identification of potential fatigue- related issues. Plans moving forward include measuring the efficacy of the training using a sample of managers from participating plants. By raising awareness of the risk associated with worker fatigue, we can help ensure a safer, healthier environment for our employees. Healthy Living Steering Team To help drive the success of our healthy living programs — and enhance the well-being of our entire global workforce — Owens Corning has established a Health Living Steering Team (HLST), made up of leaders from our human resources, sustainability, operations, and communications teams. The HLST provides critical input, sharing best practices, championing initiatives, and driving actions aimed at continued program growth and development. The team provides guidance and direction for global wellness strategies and facilitates the implementation of key initiatives through the authorization of resources. In addition, they assist in the recruitment of key operations leaders to serve on Healthy Living Aspiration Teams and support and measure their performance.
