This resonates quite a bit with me, as I just wrote a story about my husband literally losing consciousness and collapsing at work. After he was transported via ambulance to a hospital (where he was told it was "probably stress-related"), his supervisor called to tell him he'd be transferred to another facility because of prior health-related "unexcused absences" and for, you know, collapsing at work. Instead of returning to work the following week as he'd planned, he got approval from his doctor for 14 weeks off under the FMLA and is not sure if he's going to return.
I agree it's a privilege to "take a break" and as the primary income earner in my family, it's a privilege I've never enjoyed. But that doesn't mean there aren't other things we can do. The title of the story I referred to is "The Most Radical Act of Resistance is to Take Back Our Time." I'm currently campaigning for a four-day workweek (with full pay) at my job. My husband is now thinking about starting his own practice. As you mentioned, things are starting to change and it requires putting the onus on our workplaces to change, not on ourselves.
