Almost half the 42,000 workers surveyed in a recent poll conducted by recruitment firm Hays believe they'll be working a four-day week in five years, while another 16 per cent said it would be within 12 months
Another fifth said they thought it would take another decade to achieve, while the remaining fifth said the four-day week will never materialise.
It comes as research shows a three-day weekend can be like a small holiday, improving worker health, while unions say Aussies are working longer hours and finding it increasingly difficult to balance their work and personal lives.
"The optimism and aspiration from workers is clear," Hays Australia New Zealand Managing Director Nick Deligiannis told AAP.
"Clearly, from a worker point of view, that's showing that that's what their expectation is," he said.
Many employers remain hesitant about switching to a four-day week, as they face potential decreases in productivity, he said.
"I think that's one of the crucial elements of it - can we still run our business effectively? Can we still keep high productivity and not compromise the bottom line?"
But moving to a four-day week could affect staff retention rates and influence where employees choose to work, he said.
The four-day week could provide relief to staff who took on more during the pandemic, when skills and labour were in short supply.
"Workers have had to really step up and take on bigger loads, and I think there's a limit to how long people are able to do that or want to do that,"Mr Deligiannis said.
Work-life balance is much discussed but is rarely achieved for most workers, ACTU Secretary Sally McManus says.
"Australians work some of the longest hours in the developed world, it is definitely time we reduced them and shared hours with those who want more," Ms McManus told AAP.
"A four-day working week is something we should consider."
A 13-month University of South Australia study looking at the benefits of time away from work found people on holidays were more likely to be active, socialising, and getting more sleep.
While the benefits increased in proportion to the length of the holiday, positive outcomes were seen even from a three-day weekend.
"This study provides empirical evidence that people have healthier lifestyle patterns when they have a short break, such as a three-day weekend," senior researcher Carol Maher said.
Earlier this month, a parliamentary committee called for a government-backed trial of the four-day work week to see how it improved people's lives.
The trial would be based on the 100:80:100 model, which sees workers retain their salary and keep up productivity, but lose one day of work.
A number of Australian companies have already made the shift, including Unilever, Bright Agency and Fintech company Indebted.
Unilever decided to expand their trial to Australia after promising results in New Zealand, where absenteeism dropped one third, and revenue grew over an 18-month period.
A four-day week could be a tool to bring a company a competitive edge, Unliever CEO for Australia and New Zealand Nicky Sparshott said at the trial launch last year.
"This is about trying new ways to remove the barriers that potentially limit value creation and slow us down," he said.
