A staff team is made up of different perspectives, strengths and weaknesses. A good team member will be aware of their own weaknesses, and the other’s strengths. And this will lead to good fighting based on strong trust.
I will want to hear my staff team’s opinions on things I’m doing because I know my weaknesses, and I trust they are not out for their own glory, for their own portfolio or to make me look bad. I don’t have I agree with them, and I might still argue my case. But that’s exactly what should happen.
