What rule illustrates that discipline should be immediate, consistent, and impersonal?

The Hot Stove Rule effectively illustrates that discipline should be immediate, consistent, and impersonal. This concept is based on the analogy of touching a hot stove: the experience is immediate (the pain is felt right away), consistent (the reaction is the same each time), and impersonal (the stove does not discriminate; it applies equally to everyone).

In the context of discipline within a supervisory role, this rule emphasizes the importance of addressing misconduct or poor performance promptly, ensuring that disciplinary actions are applied consistently across all employees, and maintaining an objective stance rather than letting personal feelings influence the disciplinary process. This approach helps to establish clear expectations and consequences, fostering a fair and equitable workplace environment.

Conversely, the other options do not encapsulate these principles as clearly. The Cooling-off Rule relates more to taking time to gain perspective before addressing an issue, while the Crisis Intervention Rule focuses on managing immediate emotional reactions in high-stress situations. The Disciplinary Threshold Rule pertains to establishing a level of behavior that necessitates disciplinary action rather than focusing on the immediacy and consistency of the discipline itself.
