I have a person in my team who is clearly ready for the next step up. He does most of the next level job already. There’s a round of promotions every year, and I’ve suggested he puts himself forward. He said he doesn’t intend to, and doesn't think he is operating at the sufficient level; essentially he wasn’t good enough.
I know that privately he’s told another member of the team that he doesn’t think he’ll be promoted at this firm and that to advance he’s concluded he’ll need to move on.
I can’t guarantee him the next level job, it’s not my decision. AIBU to continue to try to persuade him?
