What Michael described are the technical aspects of the management function. The other equally important function of management is relationship building. Managers, supervisors and all leaders have the responsibility to engage, motivate, bring out the best in their employees. This is only accomplished through a relationship management approach, with the goal of building trust.
Trust is very critical in an organization, it's one of the top employee issues along with communication.
