I think the problem there is that there’s a lot of workplaces looking for extra people. Losing 1/5th of your workforce, but not financially is how I assume employers look at it.
The fact people are more efficient probably doesn’t mean more efficient than working 8 extra hours to them.
I could really do with a 4day workweek. And I don’t mean working 40h in 4 days.
To be honest my steam Deck doesn’t go that far beyond 4h either on a single charge when I lower all the settings.
