Planning includes setting organizational goals, finding a strategy to achieve those goals, and developing a plan to coordinate activities. Organization includes determining what needs to be done and the chain of command. Managing consists of directing and coordinating employees, and finally controlling consists of monitoring and correcting employees' mistakes. All of these functions are essential in creating an organizational structure because they form the backbone of an organization's success. If managers do not plan, there will be no objectives. If they don't organize, the organization will be dysfunctional. If they don't lead, there will be no direction in the company and, finally, if they don't control, there will be no accountability. If they ignored all these functions, the organization would not function and would collapse. However, this has a negative impact on managers. Two students from East China University of Science and Technology and a student from Beijing Foreign Studies University conducted research on "role conflict and the buffering effect of proactive personality among middle managers ” and realized that most were suffering from work-related anxiety and depression. I understand why, the support structure is not the same between CEO and manager and there are relatively many things to expect.
