If I were in the business owners’ shoes, I would likely decide to hire Jamie, the more consistent employee. While I like the idea of hiring Avery who has a much higher ceiling, I was turned off by the fact that she/he is known as a slacker. I understand that Avery can perform her job immaculately when she/he has to, but I personally prefer consistency in an essential job position like the one they applied for.
A job that someone might consider hiring Avery over Jamie is any job within a well-established company with a solid training and mentoring program. Someone with high potential like Avery might just need a little training or guidance for them to reach that full potential and no longer be a slacker. If a company hired Avery and invested some time and effort into her development as an employee, she would be a much better employee than Jamie, although maybe still not as consistent. Avery is more valuable to an organization than Jamie because the organization knows what the potential is with Avery, and they likely believe they can unlock that potential through training and other aid.
On the other hand, a job where it might be better to hire Jamie over Avery would be a job that does not take much skill or critical thinking. Maybe a job like a librarian, where you just have to be consistent and are not expected to go above-and-beyond your call of duty. Someone like Jamie would be more valuable for this job because as a librarian, consistency is more important than potential.
