Officials worried about another protest march by civil servants planned for Sunday are trying to find out how many will take part, a union says. Chinese Civil Servants' Association members and water supplies staff are planning to stage demonstrations on the next two Sundays over proposed reform and privatisation plans. Association president Cecilia So Chui-kuen said yesterday officials from the Civil Service Bureau had repeatedly sought to find out more about the demonstration this Sunday. 'The officials have contacted me and other executive council members many many times in a bid to find out how we are going to organise the event and how many people will participate. It seems that they are pretty concerned,' she said. The association said on Wednesday that some members had complained that their supervisors had pressured them not to join Sunday's protest. It sent a fax to Secretary for Civil Service Lam Woon-kwong yesterday asking if staff rights had been unduly restricted under existing laws and regulations. But Mr Lam denied senior officials had persuaded juniors not to take to the streets. 'I have checked with all the major departments. They all said that they haven't done such a thing,' he said. Mr Lam said the existing policy gave officers the legitimate right to express their opinions through demonstrations as long as public services were not compromised. Asked how concerned he was about the estimated 10,000 civil servants who protested last Sunday, Mr Lam said: 'It's a legitimate way to express one's opinion these days.'
