Launch and grow employee groups that tackle class and socioeconomic barriers at work. This practical guide defines social mobility in a corporate context, clarifies when to position efforts as “first-generation professionals,” and walks leaders through readiness checks, making the business case, chartering and governance, sponsorship, budgeting, and measurement. It includes starter templates and best practices for programming, recruiting members and allies, and aligning to talent goals (hiring, advancement, retention). You’ll also find inspiration from case studies (AMS, Argo Group, Barclays, Uber) and pointers to external benchmarks—so you can build ERGs that boost belonging and upward mobility for employees from lower-income or nontraditional backgrounds.
