I sometimes think this is because of commercial real-estate, the death of the high-street, Pret not making as much money, etc.
But more often than not I think that it is because MPs and CEOs don't actually like spending time with their families. Their work is their hobby, they don't want to be 'home with the kids', and they like the office culture they have developed over their career. In the office they are important. At home they have to do the dishes.
I think that'll be the outrage line. "They just want to work less for the same pay, expecting handouts, something something lazy entitled want everything handed to them"
I saw similar with the outrage around quiet quitting.
I truly fail to understand the logic besides protecting personal interests. By most metrics it's a success.
Unless he believes that if the council workers can be this efficient and productive in 4 days and that productivity hasn't been affected then the council workers should be able to do extra with that extra day and they obviously weren't doing enough before.
It's twisted logic, but there's a sense to it? If you manage to forget that people are people and need time away from work in order to be more productive, happier, etc
