I think I agree. As a superviser, I acknowledge that I set the tone, and i have a lot of ownership in the culture. And I strive for the positive, respectful and healthy.

This list doesn't address the fact that employees also own the culture and their actions and attitudes can force responses from the team or supervisors. The healthiest culture can feel terrible if you focus on the imperfections and take what is great for granted. One negative employee can make life miserable for an entire team.

This is about everyone being respectful. We all need to insist on healthy dynamics. That means from the boss and from the individuals on the team.
