Exactly. I spent a decade plus in a job where emails came in routinely until 9-10 at night and often the CEO would send out something on the weekend. Even if I wasn't required to respond or the response was short, this is _absolutely_ work. Over and above that, spending a decade being literally unable to get away from work in that way is like arsenic poisoning. It was like "I'm fine. I'm fine. I'm fine. I'm dead." It's insidious and terrible.
