We tried it for a quarter. Here's the unglamorous truth about the four-day week.
The good
People protected Friday-as-off ferociously, which meant Monday-to-Thursday got sharper. Low-value work was the first thing cut.
The hard
Anything that depended on other companies' schedules got awkward. Support coverage needed a real plan, not a vibe.
The four-day week didn't give us more output. It gave us less waste. Those aren't the same thing, and the difference matters.
