Sure, yes. So, let's just be clear about some of the trials that are going on. Obviously, the UK's running the world's largest trial of shorter working hours or a four-day week—70 companies, 3,000 employees all taking part in this. And we now know, because of that massive swell of interest, that we're getting constant contacts from people who are just going there on their own. Large companies, I'm sure, will be coming out soon explaining why they did this.
Now, the effects on productivity are, to some extent, easy to understand. We're talking about a lot—. In these particular organisations, which range from desk-based work to breweries to other forms of customer service—obviously, Atom Bank, so far the UK's largest employer, about 400 employees working four-day weeks, no loss of pay; so, they have customer service operations and they've just come out with more data on the increased performance vis-à-vis their customers and so on—all these different organisations have different metrics for productivity. Now, the logic of the increased productivity gains from a shorter working week is, basically, your plug-ins of productivity are not just investment in tech, but also investment in people, i.e. you have fewer people, basically, being sick at their desk—presenteeism—basically, being ill but working and not working at full capacity, or taking sick absences because they're burnt out. If you reduce that and you increase a happier, more, effectively, company-loyal workforce of those who enjoy their work, then you basically get a better performance out of them in the working week, really. And so we're talking about better per-hour productivity. Usually, or in all the cases that we worked on in terms of the trials in the UK, it was maintaining performance absolutely as before, however that is judged, but in many cases it was actually going above and beyond that, precisely because the company's giving back to their employees. And this was something that Cheney was talking about in terms of leadership or organisational change—that what if you consider your employees not just as things to work to their bone with more hours, more hours, overwork, but also things to improve the quality of their life to improve the quality of their work. So that's the logic, basically.
Now, to speak to Abigail's point about how, in different sectors, there are different challenges, that is absolutely the case—let's talk about that, let's talk about how different sectors need different levels of engagement. The public sector, healthcare, teachers and so on, will need, for example, greater investment in staff, basically, greater employment opportunities. And that's important—we need to be doing things to create more employment, basically. Public sector four-day weeks are a really important nettle to grasp, really, because then you set a standard for the rest of the economy. In our report, which Louisa was mentioning before, we looked at the potential costs, on a very conservative estimate, of what that would be for the public sector in Wales, and given that you'd be able to move whole sectors of the labour market in Wales towards a shorter working week by increasing head count and sharing that work out, which is something that Cheney was talking about in terms of the reduction of the labour required, that will be game-changing. And that's something that I think is really, really important for the Welsh Government to consider, as with all governments, and we've said the same for others as well.
