Spain looks set to become one of the first countries in the world to trial a four-day working week.
It comes after the government there agreed to launch a pilot project for companies interested in the idea.
The plan would see the working week reduced down to 32 hours - with no reduction in pay.
Suggested by the smaller left-wing party Más País, its leader Íñigo Errejón said funds should also be used to reorient the economy towards improving health, caring for the environment and increasing productivity.
Joe O'Connor is the director of campaigning for Fórsa, and chairperson of the Four Day Week Ireland campaign.
He told Newstalk Breakfast there are several benefits to such an idea here.
This includes economic benefits of motivation and productivity in employees, social benefits - such as better employee well-being and benefits for families - and even ecological ones.
"All of the studies to date have shown a very clear link between reduced working time and reduced carbon emissions, which could be really critical in our fight against climate change in the years and decades to come".
Asked about concerns over a drop in productivity under such a plan, he said the pandemic has put a new slant on things.
"I think the model we're talking about - which in New Zealand was described as the 100-80-100 model, which is about 100% of the productivity, 80% of the time and 100% of the pay - when we started talking about this when we launched the campaign in September of 2019 might have been seen as a fairly radical idea.
"But I do genuinely believe that both workers and employers eyes have been opened by the COVID experience.
"And that this model of linking pay to productivity, results and to outcomes - rather than the amount of time spent at the office or at the desk - is one which an awful lot of people have seen the benefits of".
While Mr O'Connor said he believes some version of a shorter week could be applied to all sectors.
"What we're really talking about in this campaign is about the four day week becoming the new default.
"In the same way as the five-day week, the 9 to 5, is the standard work arrangement in the economy today.
"It's obviously not the only work arrangement - and there will need to be different forms of work to suit different employers, different sectors and also different employees who don't always want to work standard hours.
"But we do believe that, in an awful lot of areas, this can be achieved at no cost - without additional employment costs".
