In my former employer, I work from Monday to Saturday, Saturday is always easy peasy, if I am still working and if I were to choose between a 2-day or 3-day weekend I would prefer a 3-day weekend. My reason: since my job is as an IT professional in which I spend the majority of my day sitting in front of my office computer it would be favorable for me to work long hours since I am not physically active (but it is mentally daunting).
