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.
