By now, all local schools should have notified parents in writing about the arrangements for tomorrow.

However, a spokesman for the Department of Education and Training said parents can also contact their own school for information about whether classes will continue or the level of supervision at individual schools.

“Responses to the industrial action is expected to vary between schools,” the DET spokesman said.

For example, Mudgee Public School principal Mark Young said the school would be open but there would be minimal supervision on the day.

“There will only be a few teachers so there won’t be normal lessons,” he said “although (students) will still have to do some academic work.”

Mr Young added that parents can also opt to keep their children at home for the day.

The NSW Teachers Federation and the State government remain at loggerheads over school staffing arrangements.

Minister for Education and Training John Della Bosca insists the changes, put in place last month, give principals and school communities more of a say when filling classroom teacher vacancies.

He said the department modified its proposal as a result of constructive suggestions from the union, but did not accept the union’s demands to delay the change for another year.

However, NSW Teachers Federation president Maree O’Halloran has accused Mr Della Bosca of spin doctoring. She said changes are “organisationally unsound procedures with grave equity implications imposed by an arrogant and duplicitous government.”
