Roles ad Relationships

Roles are the positions that are defined by a set of expectations about behavior of any job incumbent. Each role has a set of tasks and responsibilities that may or may not be spelled out. Roles have a powerful effect on behavior for several reasons, to include money being paid for the performance of the role, there is prestige attached to a role, and a sense of accomplishment or challenge.
Relationships are determined by a role's tasks. While some tasks are performed alone, most are carried out in relationship with others. The tasks will determine who the role-holder is required to interact with, how often, and towards what end. Also, normally the greater the interaction, the greater the liking. This in turn leads to more frequent interaction. In human behavior, its hard to like someone whom we have no contact with, and we tend to seek out those we like. People tend to do what they are rewarded for, and friendship is a powerful reward. Many tasks and behaviors that are associated with a role are brought about by these relationships. That is, new task and behaviors are expected of the present role holder because a strong relationship was developed in the past, either by that role holder or a prior role holder.
