Striking journalists and photographers are picketing the Fairfax offices in Sydney, unhappy with a recent decision to cut staff.
Fairfax announced on Tuesday it would cut five per cent of its full-time workers - 550 staff - across Australia and New Zealand, prompting a mass walkout at its offices, including in Melbourne and Sydney.
Almost one third of the positions to go are journalists.
Wearing t-shirts reading "Fair Go Fairfax" and "Don't Discount Journalism", about 80 Fairfax journalists picketed the offices at Pyrmont in central Sydney.
Additional security surrounded the building, a move some picketers jokingly dubbed Fairfax's "ring of steel".
The mood was fairly subdued, and those striking remained peaceful throughout the morning.
Several staff expressed frustration and disappointment at the lack of communication from their employer.
Sandra Harrison, a pictorial and visual editor at The Sydney Morning Herald, said she was upset there was no consultation with staff before the job cut decision.
"There were no discussions with editorial staff ... we were just delivered this email with no follow up that told us about all these job cuts," she said.
"That creates fear, that creates frustration, that creates anger."
Ms Harrison said she and her colleagues worked hard to get the newspaper published every day.
"We work damn hard, we put in long, long, hours, and to be told that we are overpaid and that we're not efficient ... it's a kick in the guts.
"Our efforts have been treated with contempt."
Matthew Moore, the Herald's freedom of information editor, said he wanted the journalists' fight to be made public.
"No one likes strike action. We like producing newspapers, but there is no other way of getting our message across," he said.
Earlier today, prominent columnist Mike Carlton was sacked after refusing to cross the picket line to write his weekly column for the Herald's Saturday edition.
