Ahh yeah, I've heard of that term, where there has to be some sort of a cut-off point. I agree, that working from home is tough for that, and it has to be a conscious effort to switch off.

I also find that Freelance work for clients can easily blur boundary lines, I've had a ton of people I've done music videos for who would hound me constantly until I handed the video back. One person I had was a bit of a night owl and would drop about 10 or 15 voice notes throughout the night, while I had to wake up for work the next day. No matter how much I told them not to, they didn't listen. I was glad to hand that project in by the end.
