The second of the “just cause” principles, Corey argues that this often-overlooked aspect is crucial when challenging management actions. They emphasize the importance of demonstrating that a rule is not only present but also reasonable in relation to safe and efficient work performance and business efficiency. Corey provides examples of unreasonable rules, such as a requirement to raise one’s hand to use the restroom, highlighting how the reasonableness of the rule is the crucial point of contention, rather than simply failing to follow an instruction. The discussion stresses that a supervisor must consider the reasonableness of a rule before initiating disciplinary action, and that a rule’s violation is only justifiable if the rule itself is reasonable.
