I work 4 days on, 3 off. Not quite what you’re looking for, but along the same lines. Has been no issue at all. Never has been. What I do see with my 3on/4off colleagues (usually students) is that they lack any sort of continuity in their work. Not enough time to tackle larger problems in one go and always missing out on how the smaller pieces fit together. On top of that a lot off friction when handing things off, etc. Surely it can be done better, etc etc.
