Can someone please revise my summary? Thanks! According to the survey in 2016, there is a tendency that people feel lonely and people are prone to exhaust due to work. Surprisingly, there is a significant correlation between them. Some people may contribute this to social isolation, however, according to the book, The Happiness Track, the reason is that people are tired of the corporate hierarchy. Loneliness has a detrimental effect on our health, reducing our longevity by 70%, which is higher than obesity, smoking and drinking. On the contrary, feelings of social connection can strengthen our immune system. Loneliness not only registers as physical pain in the brain but also cause counter-productivity at work. People feel disengaged at work, leading to more absenteeism, accidents and lower profitability. Some people try to figure the way in which can de-stress employees, but base on the link between workload and loneliness, research suggests that people should focus on how to contribute more social support at work. Companies should encourage the employee to develop a network by removing barriers to connect. In addition, companies should celebrate collective success, which can enhance a sense of belonging. Companies can gain a lot of return if they are willing to deal with loneliness and burnout. Otherwise, both of them can cost a fortune in countries.
