More than 44 per cent of workers are worried about the impact of the mainland's entry to the World Trade Organisation on their jobs, a survey has found. The Neighbourhood and Workers Services Centre interviewed 219 workers last month. A total of 56.2 per cent feared unemployment would worsen as a result of shifting of bases by employers to the mainland. About 66 per cent said as Hong Kong would be developing a more hi-tech economy, low-skilled workers would lose their jobs. About 55 per cent said they believed the territory's wealth gap would widen.
