I've made a very strong case for at least trialling it for 6 months. The final hurdle is convincing the CEO, who wants to see examples of technology companies who have successfully transitioned. His main concern is that software developers need five days to get stuck into difficult work… I'm not a dev, so I can't speak to that with any authority, but it would seal the deal if I could point to dev teams that work well with this format.
Do you know of any software companies who operate on a 4-day week? Much appreciated!!
