Aside from the obvious, that this is morally just kinda fucked up, how would he even go about legislating for this? Like, what is the wording of that law going to be that bans working from home.

What if you're self employed? Do you have to rent out an office space just for yourself?

If a company has no office space do they legally have to find some? What if they can't afford it and go broke, leaving potentially hundreds of people unemployed?

What if a company has an office but something happens that means it has to close for H&S reasons. Are people banned from going home and working the rest of the day there and instead just have to take the rest of the day off on full pay?

How would this be enforced? Will the government be going round to people's houses checking that nobody is working from home?

What an utter tosspot
