Final answer:
In a contemporary employee-supervisor relationship, both the employee and the supervisor are expected to adjust equally, working together to achieve organizational goals.
Step-by-step explanation:
In a relationship between an employee and supervisor, the question of who must do most of the adjusting is not black and white. Traditionally, it might have been seen that the employee needed to adjust more, but modern organizational practices encourage a balance. Both parties should be willing to adjust and work cooperatively towards the organization's goals, recognizing their mutual dependencies. Therefore, the answer to this question is D. Both must adjust equally.
