Yes. I was quite productive and happy at 4 days/week, and felt a strong part of the team that was still working 5 days/week. But when I tried a more "part-time" schedule of 3 days/week, I was less satisfied and less productive and felt less a part of the team. 4 days/week is still full-time, 3 days/week is part-time.
