...I'm not exactly sure if I'm answering this correctly, but I believe if we're talking about Career Development this may be about the Parsons' theory? The Parsons' theory assumes that a personality could be matched to an occupation, depending on those personality traits.
If someone has a career/job that feeds on specific things that person is good at, then I think they'd stick with that job. Especially if it's a job they love, and or are very happy with it! I would say certain personalities work better with certain careers.
I.. hope this helps? Lol
