Ok my bad - what I really mean (and what this 4 day week really is) is flexible hours with an increased salary. That works out as you getting the same for a day less and people doing the same days getting paid more.

All that standardizing 4 days does is lower the expected hours. This is great for people who want to work 4 days as it won't be as hard to find such jobs. This isn't great for people who want to work 5 and may struggle to find that/ be forced into 'side hustles'.

Edit - on a somewhat related note given it's a bank holiday tomorrow I am choosing to work overtime on, I need to go to sleep! Cheers.
