I work with an individual who completed a 6 month internship his senior year of college on my team, he then started on full-time on the team. It's been now a few years since he started full time. Our team is pretty small (9 people). Traditionally we have always hired more seasoned people, but due to the market and such, we focused on hiring more junior people so we can train and grow them. During team meetings and such, when our boss talks about growing the team, our boss would say something along the lines of "we'll be able to grow and hire more college grads", and nod towards my colleague. Like I said, he's been here a few years now, produces good work, has learned a lot, and has taken leadership on some new initiatives, and has overall contributed a lot to the team. He could easily go to another company and be in a more senior position. But sometimes I can't help but still treat him like an intern (or a fresh college grad). Any advice on how to approach this? Is this something that needs to start with me, or the team culture?
He has also expressed to me that he wishes our boss would stop nodding at him every time he talks about hiring new talent from college. So it leads me to believe that he still feels like people treat him like an intern. Should he just suck it up? Or perhaps move on, as the world is much bigger than just his current position.
