The author's definition of "job" happens to match yours. "Granted, your "job" and your means of employment might not be the same thing, but in both cases, you are nothing more than the sum total of your useful skills." (emphasis mine). In your example, Alice knows how to knit, do karate, write, work out, work in a shop, wood restoration, and be a receptionist. Bob may have have other skills but polite conversation ain't one of them. It's ok for people to really be attached to their job if that's what they want. Most jobs require useful skills that people work hard to attain. Alice's identity is still made up of things she does or can do.
