The Data Malarkey Podcast · 2026-05-12 · 55 min
The four-day week gets talked about a lot, but what happens when you stop talking about the theory and start measuring impact properly? In this episode of Data Malarkey - the podcast about using data, smarter - Master Data Storyteller, Sam Knowles, speaks to Charlotte Rae, Associate Professor in Psychology at the University of Sussex. Charlotte is one of the UK's leading quantitative researchers on the impact of the four-day working week. She explains how the Sussex 4 Day Week research project studies real employers, real staff, and real outcomes to understand what changes when businesses move to working time reduction. From productivity and sleep to motivation, meetings, AI, and whether the "honeymoon effect" wears off, this is a brilliant conversation about what the evidence says and where the practical challenges still sit.
