John is a young management accountant who, after completing his examinations recently, was put in charge of a small established accounts department.

At his first progress review with his superior, he was very confident and enthusiastic about numerous initiatives. John expressed disappointment that his staff were so reactionary and uncooperative.

It would seem most of the staff reporting to John are dissatisfied about his leadership. The younger ones are frightened of him and they say he his always in a hurry. The older ones who have worked in the department for years are worried about John's risky decisions. Others resent him and are frustrated that John never listens to their ideas.

Which behaviour should John adopt to improve motivation in the department?
