Wanted to chime in that I think you are conflating working in the office as being higher on the ladder than working in the warehouse. They are two different departments. The warehouse is definitely blue-collar, and the office white-collar, but that doesn't mean the warehouse workers are inferior to the office workers.

Further I checked and Stanley is a sales rep, not middle management.

I really enjoyed reading through that article series last year when I first came across it. I spent a good amount of time wondering where I fit in the hierarchy relative to my coworkers. Ended up deciding that like all models, it's useful but incomplete. Still an interesting thing to know about.

Sort of similar to learning about personality types like Myers-Briggs or Enneagram.
