It's a really entertaining read for me, but I can't place my finger on why exactly. I think crappy jobs are a great plot device in any story though since so many people have that shared experience. The ending is so satisfying to me.
You enjoyed it because the author is a great writer. I felt the same way you did. It's impressive how the story telling was so engaging while the topic is so mundane. I could see this being made into a cult-classic movie a la Office Space.
Article author here, though I'm a few days late to the party. Thank you for the kind words :)
