Teachers from both public and Catholic schools will strike side-by-side together next Thursday, in a historic first for the two unions.

The Teachers Federation and the Independent Education Union made the call after a joint meeting on Tuesday.

They’ll walk off the job on June 30, in protest of the State Government’s decision to raise the public sector pay cap to just 3 percent, and ongoing concerns about conditions and workloads in the schooling system.

It’s understood, Catholic diocesan employers follow the Government policy on wages for school staff, despite not being required to do so.

The Education Minister says she’s disappointed the unions have chosen to strike again, especially given it will be the last day of the financial year.
