Management has jumped to the defence of Post Office workers who reportedly have been skipping work. Postmaster-General Luk Ping-chuen said yesterday an investigation had been completed on claims a group of postmen at the Kowloon central office had been slack. A newspaper claimed postmen had reported for duty one hour early, at 8am, to claim an overtime allowance. They then went for breakfast for an hour. Mr Luk said postmen working on morning shift could rest for half an hour after sorting letters. 'Nobody has been slack. Postmen have to fill in an attendance notebook recording the time of reporting for duty,' Mr Luk said. 'Their supervisors would take action if staff returned late,' he said.
