Is the phrase 'work-life balance' outdated? What should we use instead?

In the last few weeks, I’ve had 3 people wrestle with me over the concept of work-life balance. I’m not even using quite that term; we call it ‘life balance’. What they’re arguing is that it’s a false dilemma, an inaccurately binary setup. Yet, the phenomenon behind it is real, so we’re fighting over words. What should we call it?
