The term work-life balance has taken a beating lately. It seems to be a favorite punching bag for grandstanding about what you really need is integration or that balance is a mirage anyway. Wat?
Balance simple means that each portion of the system has a sustainable weight which keeps the composition in harmony. Going down a pedantic, semantic rabbit hole of “well, actually, work is part of life, ergo seeking balance is wrong” is some perfidy circular logic.
