Final answer:
Rose should consider the contingency viewpoint of management in this case.
Step-by-step explanation:
Rose should consider the contingency viewpoint of management in this case. Contingency theory emphasizes that there is no one-size-fits-all approach to management. Instead, managers need to analyze and adapt their management style based on the specific situation and the needs and preferences of their employees. In this case, Rose has a diverse group of employees with different interests and motivations, so she should take a flexible approach and consider the various viewpoints and needs of her employees.
