He shared with 9news.com.au that this change has significantly elevated the interest in job openings at the company, while also leading to happier employees who maintain, or even exceed, previous productivity levels.

“I haven’t come across any reports suggesting that a four-day work week results in unhappier employees, decreased work performance, or diminished productivity,” he mentioned.

“So that sounds exactly in line with what we’ve experienced at Claxon.”

After Finance Minister Katy Gallagher said a four-day week was “not on our agenda” as federal parliament returns, Willis admitted he knows why there’s still a lot of resistance to this new-age model.

“I think there’s still a lot of fear around it and I also believe that it’s only really suitable for very structured businesses,” Willis said.

“Trying to move a business that was fast and loose to four days might be a bit chaotic.

“But for businesses that have a strong operating rhythm and are able to effectively manage and measure the change and the impact on staff and clients, I think they’ve got nothing to be fearful of.”

Willis said he expects to see more and more businesses to test out four-day weeks because you “can’t put the genie back in the bottle”.
