In October 2021, Owens Corning sponsored Operation Move, a virtual initiative in which employees, wellness teams, and site leaders committed to their activity of choice over the course of one week. Nearly 200 employees from all regions of the world took part, with many of them posting their participation on OC Now, the company’s online community. Over 350 teams representing approximately 1,500 employees took part in our annual Healthy Living Mindful Explorations step challenge, which encourages employees to learn about mindfulness practices as they track their steps throughout the day. From October 4 through October 31, team members recorded their steps each day, achieving a total of 375,747,906 steps, the equivalent of 187,874 miles. Members of the first-place teams in each region received 3,000 points on our Healthy Living platform, with second-place finishers receiving 2,000 points, and third-place finishers receiving 1,000 points.
