I can't seem to find much more detail on this particular story outside of the article, but it reminds me of that other lawsuit where a woman sued McDonald's because the coffee was "too hot". Of course everyone dogged on this person because "hurr hurr Karen of course coffee is hot", but it turned out the beverage was boiling and she actually suffered second and third degree burns. This context was left out of the initial reporting, and because of that she was harassed and mocked.
I suspect that this might be the same case here so I think I might reserve judgement before assuming she's lazy, or greedy / stupid for suing.
Also, I've been in a situation where I was alienated and constantly looking for work. It's not as fun as it sounds, and going through that experience for 20 years feels like a nightmare to me.
