That’s wishful thinking. Offices/shops/etc. will be open 8-6pm and that’s just the way they’re going to operate, because that’s what’s in the work contracts, insurance contracts, etc. It’s fixed in stone.
However we do have a very powerful tool to shift the working hours for everyone: move the damn clocks one hour. Why is it such a catastrophe that the sun would be at its zenith at 1pm?
