It might. Suppose I was a policeman and my job was to reduce crime in the city. I spend my days cruising, talking to coworkers, doing paperwork, meetings, and sending emails. When there's some emergency near me I show up, but kind of wait in the back while other officers do anything.

I would be bad at my job, and if I kept doing it indefinitely, i.e. if I wasn't quickly fired, then there would be a discrepancy between my nominal job (reducing crime) and what I actually did (nothing).
