We have a new hire at my work. He's been on board 10 to 12 weeks now. His skill set is the least of our bunch. Fair enough, we all have to start somewhere.
The problem is, he refuses to change. He's some form of Bartleby the Scrivener. Speaks 5x more than he listens. He has been asked to not do certain things certain ways, he's acknowledged those requests, and then has gone and done otherwise. He's been hand-held by people with experience very much his senior and yet he seems completely unwilling - we believe he's able - to "update his software." We've missed client deadlines because of him and he's yet to own a single misstep. The point is, it's not only himself who is compromised by his "learning disabilities."
He's not young. Fifties-ish I guess. I also haven't seen his CV so I'm not sure how he sold himself. That said, if he's typical of people in that age range I now understand why many employers are reluctant to hire the "over-experienced." It's not that they fear paying more, it's that they're not going to get current and contemporary value.
Note: Before you accuse me of age stereotyping I'm actually older than he is. I'm also skill for skill one of the least robust members on our team. But I listen. I openly ask for feedback. I'm still wanting to learn and grow. Perhaps I'm some sort of freak?
