If set up correctly, ERGs are an important part of Diversity, Equity, and Inclusion (DEI) work in the organization. That includes internal work related to the people employed but also external work related to the clients and communities in which the company operates.
ERGs can help improve representation at different levels of the organization, organize mentoring and leadership development programs, or initiate policy change that benefits all employees. With regards to external work, employee networks can be leveraged in service and product development and building corporate social responsibility.
