Managers dependence on trust and commitment from others within the firm

1- Do you believe that managers in a business firm are dependent upon the trust, commitment, and effort of others within the firm?
2- If you believe that managers in a business firm are dependent upon the trust, commitment, and effort of others within the firm, then how do you build that trust, commitment, and effort? In particular, how do you guide the business firm toward a common goal? Can you buy those attitudes and efforts with financial incentives?
3- Have you ever been a member of an organization that had a high degree of trust, commitment, and effort? Did that organization also evidence a large amount of cooperation, innovation, and unification (a feeling that everyone was working toward a common goal)? If so, what was the case? What, in your opinion, made all of that happen?
4- Have you ever been a member of an organization that had a very low degree of trust, commitment, and effort? Did that organization evidence a very small amount of cooperation, innovation, and unification (where there was nearly no feeling that everyone was working together for a common goal)? If so, what was the cause?
