Thousands of Catholic school teachers and support staff from about 350 schools across NSW and the ACT will stop work for four hours from 8.30am on Monday in the latest round of industrial action.

Staff are at “boiling point” after their Catholic employers put an enterprise agreement to a vote without gaining union endorsement, Independent Education Union (IEU) NSW & ACT branch secretary John Quessy says.

The boss of Catholic Commission for Employment Relations (CCER), Tony Farley, says he’s appalled by Monday’s industrial action.

He says it’s a scare campaign by the union designed to trick teachers into voting against their latest Enterprise Agreement.

“We’re actually giving employees pay increases and teachers will have increased opportunity for salary progression,” Mr Farley, executive director, said in a statement.

Rallies are set to be held in Sydney, Canberra, Griffith, Wagga Wagga, Albury, Bathurst, Lismore, Wollongong, Armidale, Newcastle and the Central Coast.

“This has never been done before in Australian history. Catholic employers are coming for our members’ rights and they will not tolerate that. We are urging a ‘no’ vote,” Mr Quessy said.

He said it was outrageous that employers were indicating staff needed to vote ‘yes’ on December 5 in order to get a pay rise.
