An affinity group is defined in Merriam Webster as “a group of people having a common interest or goal or acting together for a specific purpose.” In the workplace, you may also refer to it by its more common corporate synonym, “employee resource group.”
ERGs or affinity groups can be anything from sports leagues to book clubs to other random groups where employees hang out to share a common interest—but they’re often the most powerful when they’re focused on creating a diverse and inclusive workplace.
