First of all, many people in the health service do work less than a five-day week. It's part of the changing nature of the way in which people who occupy those very pressurised roles choose to make their own future. It's part of the reason why we have more people working in the Welsh health service, in every single aspect of it, than ever before.

We're always willing to look at ways in which the working conditions of people across our public services can be improved. It's part of the discussion that the health Minister has been having with our health service trade unions. A four-day working week is something we know that some businesses in Wales have already embarked upon because they believe that it delivers better productivity and a more contented workplace than would otherwise be the case. We will look carefully at the lessons of that. There is to be an experiment in Scotland. It's yet to begin, but I've discussed it with the Scottish First Minister and we will look to see whether there is anything we can learn from that. The notion that a rapid and wholesale move to four-day working in the health service would be likely to lead to better outcomes for patients is something that I think would need a good deal of examination.
