Employee resource groups Our employee resource groups (ERGs) are voluntary, employee-led, company-sponsored groups that focus on making a difference among our U.S. employees. ERGs can help employees make authentic connections, showcase leadership skills and create a positive impact. Additional benefits of ERGs include: • Strengthening employees’ sense of belonging. Employees have the chance to share experiences and build support networks that stay with them for a lifetime. • Building community. Employees are a part of a group that creates positive change and growth. • Creating exciting opportunities. Employees can build on current skills and discover talents, providing another method to develop personal and professional potential. • Driving business value. Employees can join forces across the business to identify ways to deliver on culture and talent initiatives as well as with customer and market connections.
