The four-day working week keeps making headlines, yet most UK businesses still work a traditional five-day week. So what's actually going on? In this episode, you'll hear what two conflicting 2025/2026 studies really say about four-day week trial success rates, why the model suits some businesses far better than others, and the practical questions - pay, contracts, holiday calculations, customer cover - that need answering before you even think about running a trial. You'll also get a clear, honest look at employee productivity claims, work-life balance benefits, and why flexible working UK might be a better starting point for your business than a full four-day switch. The data on the four-day week is genuinely mixed, not universally positive. One 2025 study of 141 organisations across six countries found 90% kept the model after their trial, but a separate 2026 study found only 51% of trialling companies made it permanent - the headlines rarely mention both.
