　　If you try to contact Indy Cube (a provider of workspaces) after 5 p.m., you receive an automatic message that would make a good demonstration for the fast-growing four-day week movement, “we’ll get back to you pretty quickly during working hours,” it says, “if you’re messaging us outside of these, we’re probably busy with other things, like horse-riding, dancing, or good sleep.”

　　“This week we have had people contact us from Japan, Canada, the UK, France, Switzerland.” said its founder Andrew Barnes. The day off that each worker takes varies, depending on the team’s needs at the time, but there has been a change in culture with “less time surfing on social media and fewer unnecessary meetings.” said Barnes. However, Kate Cooper, policy director at the Institute of Leadership and Management argues the reasons behind increases in productivity are not yet clear. Cooper said that “the Hawthorne effect” may be in play, that is, people change their behavior simply because they feel they are being observed—in this case they feel that by being granted a four-day week they believe their bosses are interested in their work. “How sustainable is that?” Cooper doubts.
