Final answer:
Zereth's struggle to encourage and motivate her new department with her former management style aligns with the contingency perspective of management, which emphasizes the need for flexibility and adaptation in leadership to fit different situations and employee needs.
Step-by-step explanation:
Zereth's experience would best fit the contingency perspective of management. This perspective suggests that there is no one-size-fits-all approach to management; instead, successful leadership adapts according to the situation and the specific needs of the staff and the environment. Zereth's previous management style may have been successful with one group, but it's not necessarily transferable to a different group with different motivations and dynamics.
In her new department, Zereth is recognizing that incentives that worked before aren't as effective, indicating that her staff may have different needs or motivations. Under the contingency perspective, she'd assess the situation and modify her leadership style to better fit her new team's needs. This perspective acknowledges the importance of flexibility and adaptive management strategies in changing environments or with different groups of employees, which seems to align with Zereth's current challenge.
