Cathay Pacific flight attendants have rejected the company's decision to withhold bonuses, with some members suggesting industrial action, according to their union. Wilson Lee Ying-man, a spokesman for the Cathay Pacific Flight Attendants' Union, said it had received more than 600 complaints about the issue in less than a week. Mr Lee said the union hoped to resolve the issue through discussions with the company. The union sent a letter, rejecting the 'de facto pay cut', to company chief executive David Turnbull on Monday. 'We hope there will be no action and we want to keep a low profile,' Mr Lee said. Cathay Pacific announced last month that staff bonuses would be withheld, citing financial difficulties resulting from the September 11 attacks on America and the global economic slowdown. 'But they are not losing money, even up to now they are withholding pay while making a profit,' Mr Lee said. 'The loss is only that compared with last year, which was an exceptional year.' The letter to Mr Turnbull stated that flight attendants had a 'legitimate expectation' to be paid the 13th month salary as it had never before been withheld - not even during the global stock market crash in 1987, the Gulf War in 1991 or the worldwide recession in 1998. 'The pressure on Cathay management to maintain high profit levels . . . is undeniably what is fuelling current measures,' it said. But Cathay spokeswoman Lisa Wong Lai-shan said withholding the bonus would help the company preserve jobs and business. 'The situation right now is very unusual - planes crashed into buildings - and there is a global economic slowdown,' she said. 'The civil aviation industry is under extraordinary pressure.' Ms Wong said the company would continue discussions with the union and identify ways to help alleviate any financial burdens imposed on staff by the cancellation of the bonus.
