Journalists at Nine Publishing will begin a five-day strike on the eve of the Olympic opening ceremony after rejecting a revised enterprise bargaining offer from management.

Media, Entertainment and Arts Alliance (MEAA) members at The Sydney Morning Herald, The Age, The Australian Financial Review, Brisbane Times and WAtoday will walk off the job at 11am on Friday morning.

Union members voted to reject a new offer from management at stop-work meetings in newsrooms on Thursday afternoon.

MEAA director Michelle Rae said reporters at Nine were being asked to do "more for less".

"Journalists have asked for a modest wage increase in line with the CPI after foregoing any pay rise during COVID and at a time when the company is making record profits," she said.

"It's totally unacceptable that the company is asking workers to make a choice between a modest pay rise and the possibility of more job cuts."

Ms Rae said the decision came after 90 redundancies were announced across the publications due to the end of a funding deal with Facebook parent company Meta.

Staff feeling 'volatile', The Age journalist says

Rachael Dexter, a journalist at The Age and an MEAA union delegate, told the ABC the temperature among staff had been "volatile".

"Staff have been very clear in their demand to management that any pay offer has to make a genuine attempt to match the escalating cost of living that we're all facing," she said.

Ms Dexter said while staff were committed to walking out, they would welcome any offer from management to come back to the negotiation table.

The strike comes as 18 Nine staffers have travelled to Paris as part of planned coverage for the Olympics.
