ERG Intelligence: What Every Leader Needs to Know about Employee Groups

Book was fully updated Dec 2025

Nearly every organization with 100+ employees has employee resource groups (ERGs)—also known as business resource groups (BRGs), affinity groups, or employee networks. Yet many struggle to make these groups effective, sustainable, and aligned with business goals.

ERG Intelligence breaks down what the latest research shows: when ERGs are well-supported, they strengthen employee engagement, retention, leadership development, and workplace culture. In today’s complex business and social landscape—marked by shifting DEI expectations, political scrutiny, and rapid change—well-run ERGs are more essential than ever. They offer trusted structure, meaningful connection, and leadership when organizations need it most.

Written in a fast, easy-to-read FAQ format, this practical guide helps leaders move ERGs from well-intentioned to high-impact. Inside, you’ll find:

• Clear definitions of ERGs, BRGs, affinity groups, and employee networks

• Real-world examples of what effective ERGs look like today

• Proven best practices for ERG leadership and oversight

• Fill-in-the-blank templates for training, governance, and operating guides

• Actionable guidance for ERG leaders, managers, HR partners, and executive sponsors

Whether you oversee multiple ERGs, lead an employee group, or support inclusion and engagement strategy, ERG Intelligence provides the tools and insight needed to build employee resource groups that create measurable value—for employees and the organization.
