Substantial's first ERG started as a Slack channel created soon after we adopted that tool. It gave Substantial's women a place to talk about topics unique to them, whether it was to commiserate or address a specific issue. Formalizing that structure, the Women's Group is now a regular in-person gathering as well that has an agenda to address immediately germane things and allow time for emergent topics as well. These meetings take place away from the office, creating even more of a comfortable environment for participants to be open and vulnerable.
