Someone else said it is measured by: sales revenue per employee So I think you're right. I still think people will be suspect. Like why couldn't more work be done in a 5 day week compared to a 4 day week? Why would 4 day produce the same work which result in the same sales as 5 day? And it's hard to logically argue for or against. But if you tried a 6 day week, you could try to answer: well does more working hours result in more work with more sales output? And if not, then maybe the truth is that there's a max budget of real work per week for employees, and more work hours just go to waste. And in turn that could explain why 4 day over 5 didn't see a big change on sales output.
