Companies say it is hard to find good developer talent, but if they were willing to switch to 4 days a week I'm certain they would have a long line of great developers lined up outside their door. I imagine it would quadruple the applicant pool and double* the talent of the average developer applying. Also I think if anyone wants to convince some employers to allow for a 4 day week focusing on attracting and retaining talent is more important to companies than the 20-25% pay cut. *Because the average developer who applies to a position is probably in the bottom quartile, but the large number of dev's interested in a 4 day work week would bring the quality up because these would be closer to median developers.
