tool consisted of 16 questions that measure the leadership style of the nurses' managers. The
possible responses of this part were yes scored (I), and no scored (0). The questionnaire is
divided into three parts (each part involves six questions) the first six questions detected the
directive leadership style, the second six questions detected the participative leadership style, and
the last six questions detected the permissiveness leadership style. The result denoted that there
were no statistically significant differences between leadership styles and assertiveness among the

of sharing of the nurses in decision - making, policy making, informing the nurse managers with
description of each position, the nurses ' managers must have authority commensurate with their
responsibilities, and must have adequate opportunity for promotion, professional growth and inservice
