Landing a well-paid job in a foreign company is something millions of China's jobseekers dream of, but the findings of a recent survey may change their minds.

　　Nearly 90 percent of Chinese staff in foreign companies suffer from work-related illnesses, according to a recent survey by the Horizon Research Consultancy Group.

　　Of the 1,521 respondents working for foreign companies, 91 percent reported symptoms such as burnout, stress, frustration, lack of sleep or numbness in the neck and shoulders after work, said Horizon. Those interviewed cited a total of 27 work-related symptoms. 　　

　　Interviews were carried out over the telephone, via e-mail or fax or face to face in four cities including Beijing, Shanghai, Guangzhou and Wuhan. 　　

　　And 15.4 percent of those surveyed said they suffered from at least seven symptoms, which could lead to a breakdown or serious illness according to Horizon analysts. 　　

　　Another 5 percent said they suffered from at least 10 symptoms, which indicated they were extremely overworked, said Horizon. 　　

　　Half of the respondents said they did little physical exercise, while many complained about working more than 10 hours a day, returning home late at night and having to work over weekends. 　　

　　Of the most common symptoms of interviewees, 30 percent said they suffered from poor memory, as well as stress, mood swings and accelerated aging. 　　

　　Middle-aged, highly paid employees were more vulnerable to work-related illnesses, according to the survey. 　　

　　About 15.8 percent of the middle-aged respondents said they showed at least seven symptoms. 　　

　　Of the group earning more than 8,000 yuan ($1,025) a month, 19 percent said they suffered at least seven symptoms of being overworked.

　　A lack of regular health checks and an unhealthy lifestyle, including drinking, smoking and skipping breakfast also made matters worse, according to the survey.
