The "Work-Life Balance" Myth Is Actually Harmful To Both Employees And Employers — The Entire Framework Relies On A False Premise About Human Capacity That Has Never Been Empirically Validated

We need to stop calling this balance because it assumes two competing interests can coexist in a single individual over time, which is not how capacity works. You either have the bandwidth or you don't; framing it as a tug-of-war creates a constant sense of failure regardless of output — if you work more you sacrifice rest, if you rest more you fall behind. The "balance" narrative was sold by management theory to make labor exploitation palatable through language about flexibility, and now employees have internalized that their inability to do both is a personal shortcoming rather than an obvious structural contradiction. We should be talking about boundary boundaries instead of balance — rigid separation between work time and non-work time enforced structurally, not negotiated individually through vague promises of "flexibility" that always resolve in favor of the employer because capital has the leverage.

The "false premise" claim is doing a lot of heavy lifting and I want to pin down exactly what you mean by it because right now this thread is conflating three distinct ideas into one big rhetorical target, which makes the entire argument brittle:

First, are we talking about capacity as in circadian/hormonal limits? Because if that's your angle, there's a legitimate physiological floor where sustained cognitive output degrades regardless of how much you want to keep going. Sleep deprivation affects executive function and error rates long before it feels uncomfortable. So the premise isn't "false"—it's biologically real.

Second, are we talking about capacity as in infinite scalability of any specific skill set? Then yes — no one can be a world-class coder AND write fiction AND raise kids to adulthood without something suffering. The tradeoff is empirically well-documented via opportunity cost calculations that predate this entire conversation by decades. But the thread frames this as "a myth" rather than a trade-off, which is confusing.

Third — and I think this is what you're actually getting at — are we talking about capacity as an additive bucket where work hours + life hours = 168/week? That model IS
