Earlier quoted context omitted.
The entire point of this is that productivity does not go down in a 4 day workweek and retention goes up. As an employer, you get the same amount of output, happier employees, and better retention. Everyone says they’re a data driven business until the data tells them something they don’t believe.
> The entire point of this is that productivity does not go down in a 4 day workweek Just an anecdote, but: my productivity definitely took a huge hit when I reduced my hours to 4days/week. All of the "working harder/more efficiently/more focused" doesn't help if you already worked hard/efficiently/focused. If you have a job with a lot of slack/downtime/waiting time... Sure. But sometimes, working 20% less means that…
Personally I'd think of the extra day as rent paid on not having to hire and onboard someone new.
