Can someone please revise my summary? Thanks From a long time ago, philosophers and psychologists have discussed the importance of self-control for a long time. In terms of scientific study nowadays, there are hundreds of studies showing that the benefits of self-control at school and at work. But, what happened if people don’t have enough self-control at work? According to research, self-control is a limited resource. If people don’t replenish, it may have negative effects of self-control in the future. For example, managers who always need to smile at their customer may show impoliteness to their subordinates. There are some consequences related to the lack of self-control: First of all, people increase deviant behavior. Secondly, they decrease volunteer behavior. Thirdly, they lower the job performance. Finally, leaders without the self-control tend to form a negative atmosphere, causing the counter-productive results. Without doubts, it’s critical for companies to help employees maintain self-control. There are three key factors to solve the problem. First, people who have enough sleep can exercise more self-control. Also, working for long hours can be detrimental to the efficiency. Second, service-oriented employees should not hide their emotions, otherwise, it may cause burnout and lower satisfaction afterward. Finally, establishing an ethical culture can prevent employees from taking up unethical things.
