Final answer:
To disprove the nurse's claim of unfairness, the closed systems theory would look at whether the nurse broke the established rules, here excessive call-ins before shift change, and if the consequent suspension follows the policies laid out, which would mean the action was fair.
Step-by-step explanation:
The nurse's statement, 'You are unfair to me', regarding the policy for call-ins can be examined under different organizational theories. However, to disprove the statement that the policy is unfair, we would reference the closed systems theory. Unlike the open systems theory, which would consider external factors influencing the nurse's behavior, the closed systems theory does not factor in these external influences and focuses solely on whether the rules were followed. In this case, if the policy was clearly communicated, consistently applied, and known consequences were enforced due to the nurse's actions (excessive call-ins within 15 minutes of shift change), then from the viewpoint of the closed systems theory, the suspension could be seen as a fair consequence of breaking established rules.
