Novopay is a deeply flawed payroll system that is falling apart, says Lakeview School principal Ed Hodgkinson.
Mr Hodgkinson said errors persisted through the first pay round for the year on Wednesday with a teacher receiving payment for only five of the 14 days she had worked, overpayments going to several other workers, and the collapse of an online communication link with the payroll provider, he said.
"We're still having incredible issues with Novopay. I think we need to go back to scratch and start again. It's been a nightmare," Mr Hodgkinson said.
An example, he said, was the breakdown of a system of online forms that schools were to complete and submit to Novopay when a payroll error is discovered.
He said schools were able to call a hotline number to help resolve errors although there was a risk of "waiting on the phone for two hours to be finally given the wrong information".
