Thousands of doctors in public hospitals and clinics will launch industrial action this month in protest at a Hospital Authority move to cut salaries for new recruits. A council meeting of the Public Doctors' Association last night unanimously voted to start action in three weeks and appointed a working group to work out details. 'We're serious,' said spokesman Dr Andrew Yip Wai-chun. 'We feel we're being betrayed by the Government. The Hospital Authority should press for funding rather than cut staff.' Industrial action would include refusing to write medical reports and boycotting meetings, Dr Yip said.
