According to the Kadushin Study, which is a shortcoming from the supervisor's point of view?

The selection of personal traits such as rigidity as a shortcoming from the supervisor's point of view is valid because rigid supervisors are less adaptable to the diverse needs of their staff and the dynamic nature of the work environment. A supervisor who exhibits rigidity may struggle to foster open communication, which can stifle creativity and innovation among team members. This inflexibility can also lead to frustration and disengagement within the team, ultimately affecting service delivery.

On the other hand, encouraging staff development and advocacy for staff are typically viewed as positive traits that enhance the supervisory role. These qualities contribute to a supportive and constructive workplace culture, benefiting both the staff and the organization. Limited experience, while a potential concern, doesn't necessarily denote a character flaw or personal limitation as rigidity does, but rather reflects a potential lack of exposure or skills that can be improved over time. Therefore, rigidity stands out as a more significant and detrimental shortcoming in the context of supervisory effectiveness as noted in the Kadushin Study.
