Workplace friendship starts to fade after coworker gets promoted and begins acting like the boss he used to complain about: ‘I don’t recognize him anymore’

Workplace friendships often feel solid… Until roles change. 

A promotion brings greater responsibility, higher expectations from upper management, and the need to demonstrate your ability to handle a new role. You earn opportunities for professional development and career growth, which are some of its biggest advantages. Still, it can mean increased stress, more pressure, less freedom to act casually, and the challenge of earning respect while maintaining fairness. And sometimes, relationships with colleagues start to change. That's exactly what happened to the employee in today's story. His coworker's rise to team lead didn't just change their workplace dynamic; it also transformed a friendship he thought would last.    

In the end, work is work. Transitioning from one role to a bigger one can be challenging for almost anyone, and many people struggle to find the right balance between authority and flexibility. But there's also power at play here. Some people change their personality when they gain more power because they begin to see themselves differently. Their behavior shifts based on what they believe a 'leader' is supposed to be, and their past experiences with supervisors may shape their vision of leadership, too. Others may simply like the feeling of having more control over others. 

We don't know what kind of internal process this coworker is going through, but one thing is clear. He's acting more rigid and overly professional with a friend. Can we blame him? Probably not. We assume that he's doing his job and he's trying to do it well. A manager isn't supposed to treat one employee differently from others, and close friendships can complicate fairness when it comes to performance reviews. But his friend's feelings are valid too. The person he used to laugh with at lunch breaks now feels distant, and getting used to that new dynamic can be hard to digest. Watching a friend change can feel like losing someone, even if they're still sitting at the next desk. But in the workplace, what once felt like friendship may turn into professionalism, and that's not always a betrayal. Sometimes, it's just a new reality we must accept.

  • Me and this guy at work had been pretty tight for like 2 years. Same shift, same lunch breaks, we used to vent to each other about management constantly.

  • He was one of the more down to earth people I knew there. He got promoted to team lead 3 months ago and I don't recognize him anymore.

  • Like he slowly became the exact type of supervisor we used to complain about together. Nitpicking everyone, performing for upper management, barely acknowledges me unless he needs something covered.

  • Last week he pulled me aside to "formally" let me know my performance needed to improve.

  • Out of nowhere. No prior complaints, nothing. I had to stop myself from saying something because this is literally someone I used to clock in late for so he wouldn't get flagged.

  • I'm not even bitter about the promotion itself, good for him. I've had money from Stake saved on the side so im not desperate to stay either way.

  • But the friendship part is what actually got to me a little. Is it even worth bringing up at this point or do I just accept that some people change when they get a little power and quietly move on?

  • Gold_Interaction5333 Seen this a bunch on the floor. When someone jumps to lead, they're suddenly responsible for metrics, attendance, and write- ups. Corporate starts watching their numbers, not their friendships. I'd keep it professional for now. If you talk, do it off-shift and casual. But don't expect the old dynamic back.

  • Outside_Cry_3054 It's called growth and responsibility. He got promoted and his responsibilities changed. Regardless of how it used to be he has a job to do and it sounds like he's doing it. Honestly, the fact that you guys were so close and he's telling you that you need to do better probably means that you really do. With every promotion there comes more responsibilities and you also start seeing things from a bigger picture. I would suggest stepping up and growing yourself... Some people are

Nitpicking everyone, performing for upper management, barely acknowledges me unless he needs something covered. You cannot be friends with the people you manage. Its not fair to them or their colleagues when it comes to performance reviews. When you become a manager you have to take a wider view and ensure people's perfor

  • RainbowRotten A) Your feelings are valid and completely understandable. B) Not worth the talk. The truth is we all do what we have to do to survive. Unfortunately, that means relationship dynamics change. Especially when in work environments where we go from coworkers to supervisors. It's uncomfortable for everyone.

  • IntrepidMuch No, don't bring it up. There is nothing to gain going down that path. He's being watched as much as he's watching. He's also still trying to figure out what kind of boss he wants to be (remember he only knows the bad kind.) He is neither right nor wrong. He's just trying to figure it out.

  • User123466789012 I don't personally see a point in bringing it up, your relationship at work has different dynamics and it just is what it is now. My transition from individual contributor to supervisor was insanely difficult. Many of us go through experience. Work is work. Unless it's impacting some friendship outside of work and that bothers you, he's just doing his job. He's not going to treat you any different than others, nor should he.

  • RunnersHigh666 Move on. Friendship over. Do your job and don't bring emotion into it.
