A few weeks ago, I interviewed the owner of a Chick-fil-A franchise who had decided to offer his employees a 3-day work week.
Verdict: They loved it, they were more productive and less likely to leave, and when word got out about the program, job applications went through the roof.
I'm glad it worked out for them, but squeezing a full week's worth of work into three days seems a bit extreme. And for that matter, what ever happened to the idea of a four day work week?
