Final answer:
Juan's belief that rules should be flexible aligns with the contingency perspective of management.
Step-by-step explanation:
Juan's belief that employees and situations are unique and that rules should be written with options to apply to different situations or be flexible aligns him with the contingency perspective of management.
The contingency perspective recognizes that there is no one-size-fits-all approach to management and that the best way to manage depends on various factors, such as the employees and the situation at hand.
For example, in a contingency perspective, a manager might use different leadership styles or strategies based on the specific needs and characteristics of their employees or the task they are working on.
