I tried this. For about 4 months I worked for a business 4 days a week.<p>It was a complete nightmare because I had responsibilities. I found I had to fit 5 days of work in 4, and the day I wasn't there, it didn't seem much got done.<p>In conclusion, I found that it made me work a lot harder, disconnected me from ongoing projects, playing catch up, and missing important 'meetings'. Not to mention the fact that you're taking a decent paycut for no apparent reason.<p>That free day didn't end up being productive in any other way nor was it less stressful weeks.<p>Granted, that business was a mess. But still, I don't see this really working, unless everybody has the same day off and works 4 days a week. Then I think it would be super.<p>Also if more people work 4 days a week but don't take the same day of the week off, the company turns into a country club, with more gossip and "I wasn't told anything about this" commonly heard.<p>My (hurt) 5c.
