I have a feeling the problem here is more to do with reporting on a loosely worded poll than anything else though.
So any time you are spending resting is, effectively, sinful.
Most people don't put it that way these days, but the basic idea is still deeply embedded in so much of American culture.
Vacation is a normal thing: culturally, we have a strong understanding of it, and an agreement that going to visit another country, or to Disneyworld, or for a camping trip, is what you're supposed to do with paid time off.
But just resting? Well, that's just selfish!
It's the "just you know...resting" one that might be a problem. It's not the resting itself that is a problem. Everybody needs to rest. The problem is when people need to take PTO in order to get time for that rest.
Any reasonable job already includes enough time off that workers should be able to get all the rest they need without having to use up some of their PTO.
What if someone actually wants to stay home, and relaxing and relieving stress is playing a new video game or working on some personal project, or even just you know... resting? I did not think the work/life balance meant never having any time to yourself. Even on weekends, people ask "What are your plans?" as if "nothing" is the wrong answer.
