The best predictor of toxic work culture

To find evidence-based insights on culture change, we began with the large body of existing research on unhealthy corporate culture. Leadership consistently emerged as the best predictor of toxic culture. The importance of leadership will surprise no one, but it does underscore a fundamental reality: Leaders cannot improve corporate culture unless they are willing to hold themselves and their colleagues accountable for toxic behavior.  Toxic social norms can take on a life of their own in a team or an organization and persist through multiple changes in leadership. Without a commitment from the top team, any organization wide culture change — including a cultural detox — is destined to fail.
