The number of vacancies in the private sector were up 9 per cent in June compared with a year earlier, figures released by the Census and Statistics Department yesterday show. Most increases were in the restaurant sector, with vacancies surging 56 per cent to 3,400 in June, compared to the same month last year. The job market is also active in the communications and educational services sectors, with the former recording a 53 per cent increase in the number of vacancies and the latter a 57 per cent rise. The chairman of the Hong Kong Telecommunications Industry Employees General Union, Ha Chi-hung, said he had observed a higher turnover rate over the past few months. It was getting more difficult for employers to retain workers now as telemarketing sales staff kept switching jobs all the time, he said. But Juo So-in, of the Catering and Hotels Industries Employees General Union, said the real situation in the restaurant sector was not as promising as the figures may have shown. 'A lot of the extra jobs are low-paid and casual work, for which the employers can fire the workers any time they are no longer needed,' Ms Juo said. But the union had received fewer complaints from workers about unpaid wages. Last year there were one or two restaurants closing every month, but there had been only two or three cases reported to the union over the past three months. But the economic revival has not helped much to increase jobs at private construction sites. Government figures show 52,300 workers were employed at construction sites on private projects in June, 7,700 less than in the same month last year. Hong Kong Construction Industry Employers General Union chairman Choi Chun-wah said the situation would have been worse if 10,000 local workers had not left Hong Kong to take up employment in Macau.
