Final answer:
When a senior deals with a situation themselves, it is referred to as delegating. Delegating is a management skill where leaders assign tasks to subordinates. It is beneficial for managing workloads but can lead to increased conformity costs.
Step-by-step explanation:
When a senior can deal with a situation themselves, the most appropriate term from the provided options would be delegating. Delegating involves entrusting a task or responsibility to another person, usually someone who is a subordinate. In business and management contexts, delegation is a key skill that enables leaders to manage their workload effectively by assigning tasks to other capable individuals, thus reducing transaction costs associated with decision-making processes. However, it may lead to increased conformity costs if the delegate does not have the latitude to make independent decisions.
Collaborating would involve working jointly with others to solve a problem, which is not suggested in the scenario where the senior is handling the issue independently. Avoiding and competing are conflict management strategies that are not directly related to handling tasks or decision-making responsibilities.
