Final answer:
According to Linda Hill's study, after a year on the job, most managers continue to struggle with work overload, despite becoming more comfortable with other areas of their roles such as conflict resolution, role definition, and work relationships.
Step-by-step explanation:
According to Linda Hill's study, after a year on the job, most managers became comfortable with various aspects of their roles, but there is one thing that generally remains a challenge. Managers became more adept at handling responsibilities such as conflict resolution, defining the managerial role, and managing work relationships. However, the aspect that many continue to struggle with is work overload. This is often due to the increased responsibilities that come with management positions, as well as the ongoing need to balance strategic leadership with the daily operational demands of the role.
Considering the context provided by the study, it is clear that managers may find ways to adapt to their roles and develop the necessary skills for managing teams and projects, but the sheer volume of work can continue to be a significant stressor.
