I am team leader of a software development team and thanks to tolerance of my boss I have a 4-day work week for past 20 months (Monday - Thursday, 8 working hours per day on average). The rest of my team (and also rest of the company employees) is working 5 days. Compared to 5 work days per week I feel my work is much more focused, better organized and prioritized. there is no space to spend 1 hour a day reading hacker news. The team does not seem to suffer from the fact I am not there at Friday. they have the option to call me via phone if they get completely blocked in some issue (such a call occurs maybe once in two months). I try proactively to avoid being the blocker any time by replacing email communication by issue tracking and shared intranet boards and documents as much as possible.
