Is the 4-Day working week the solution to the fuel crisis?

Genuinely interested in what the r/nz whanau think about this.

I've seen this mentioned a few times as a possible solution to the possible looming fuel crisis.

As far as I can see, there would be huge benefits to moving to a 4-day week. I guess those 10 hour days would be harder, but I would personally sign up to this in a heartbeat. You would need to align schools of course but I honestly can't see any downside.

What do you think?
