I'm not sure how this is relevant. I'm sorry for your wife having to go through that. That's a shitty job. But I think the premise is about working in general, not a specific job. As a thought experiment, if you and your wife had a billion dollars, would you still work? Would you still do things that are work? Or would you fly around the world vacationing all day, watching TV, or things like that. If it's not the latter then that's the premise of the article: people find fulfillment in work.
