Working in an organization where I, Me, and You come before Us can be painful for everyone. In a way, everyone has a sword and is fighting battle among each other. Instead of working together, we are all fighting to prove ourselves corrected.
An organization is about working together and solving pain points for stakeholders. With in-fighting and divide, an organization is a dysfunctional system in itself.
The responsibility of building an organization is not only with the HR head but the founders, leaders. It is a full-time role like fundraising, marketing, and sales. With the modern era of build, fast-break things come with their own curse.
