New international studies have again highlighted the difficulties multinationals have retaining staff in China. According to worldwide recruiter Manpower the "available talent pool" has to almost double in the next seven years to maintain current economic growth, the Financial Times reported. In its own study, Mercer Human Resources Consulting found that 54% of employers in China had seen more turnover in professional staff and 42% had noticed higher turnover in support staff. The average employee aged 25-35 is now likely to stay at a company for just one to two years, Mercer found. "Companies are starting to realise they need to be more sophisticated in their approach to employee attraction and retention," the report said.
