I am a high school English teacher in a suburban district outside a large midwestern city. There is a large variance between how much work members of different subject areas bring home. I certainly have colleagues that work their 40 hours and don’t spend a minute more thinking about school. The nature of my work is different, and I typically work 50-60/week.

Also for reference, I have been working as a teacher for 6 years and make just shy of 43k.

The "article" was produced by a neocon think tank. https://en.wikipedia.org/wiki/American_Enterprise_Institute

It's a "study" in the sense that a blog by the American Tobacco Association (fictional entity invented for the purpose of this argument) produces "studies" about the "harmlessness of tobacco smoking".
