A study of grass-roots workers in an enterprise shows that grass-roots workers who use social software are significantly less likely to suffer from diabetes, mental illness and ischemic heart disease than those who do not use social software. Accordingly, the managers of the company believe that the use of social software is beneficial to the health of grass-roots workers.
The statement 'The grass-roots workers of the enterprise are under great pressure, and people with physical and mental health use social software after work' will most weaken the above managers' conclusions.
