Stress and psychological pressure play an important role in creating behavioral disorders. Various studies show that a considerable percentage of employees in any organization are affected by harmful impacts of stressful stimuli. Hence a knowledgeable manager must attempt to provide good working conditions and facilities to improve productivity of the organization while keeping physical and mental health of staff. This research was conducted with goals such as review of employee job satisfaction and fulfillment in different dimensions of inter-organizational factors (including organizational strategy, organizational structure, and organizational process) as well as work environment facilities, physical conditions and most importantly, the relationship between performance and the way tension and stress among staff is managed. This paper tries to explain the role of managers in reducing and coping with stress and psychological pressures and keeping mental health of staff.
