4roddas writes: Work-related RSI cases are at an all-time high and the cost to businesses is spiralling, new Microsoft research reveals. Repetitive strain injury cases have soared by over 30 percent in the last year, costing businesses over US$600 million in lost working hours — and causing pain and debilitating discomfort to over-worked staff. Microsoft claims the rapidly emerging trend of 'mobile working' — with office-based employees now working on the move for an average of an hour more per day than they did two years ago using laptops and mobile devices — is behind this alarming climb in work-related injury. The company arrived at its conclusions in a poll among over 1,000 office workers, HR managers and office managers. This showed rthat 68 percent of office workers suffered from aches and pains, with the most common symptoms including back ache, shoulder pain and wrist/hand pain.
