Spoken like a true middle manager :) I was one myself until a few years ago, I hated managing staff.
The 5 day work week is a social construct anyway. Life for all would be better if we all had a little more leisure and time to relax, not to mention other benefits like reducing traffic and emissions. When people are well rested there is less mental health problems, road rage, and generally make clearer decisions. Burnout is a huge problem across the workforce, at all levels.
