No matter how we organise ourselves, we will always be in siloes one way or another. There will be organisational divisions. It’s important to connect people across those divisions as well. One way to do that is communities of practice , a k.a. guilds or chapters. Here’s another.
There is a good article on Employee Resource Groups here.
“ERGs have formed within the workplace to support and represent people with identities and demographics related to gender, race, sexual orientation, ability/disability, caregiver roles, military status, religious affiliation, generation, geographic area, job function, and more,”
This is an important idea. Guilds built around a specific skill are not the only way to create connections across tribes. Groups built around a personal need are just as important.
