WORK MAKES you ill, and things are getting worse, says a new Health and Safety Executive study. It found a 122 percent increase in work related illness between 1990 and 1995-6. As many as 1.3 million people reported work related illnesses in 1995-6. Some 58 percent of them suffered from upper limb, lower limb or back disorders, and about a third took time off because of stress. Manual workers account for 72 percent of all reportable workplace injuries.
