Managing Former Peers: How to Lead the Team You Used to Be Part Of

Managing former peers is what happens when you're promoted to lead a team you were, until recently, a member of. The people you now manage were your colleagues last month — people you had lunch with, complained about the organisation with, and perhaps competed with for the very job you now hold. It's one of the most common leadership transitions there is, and one of the least talked about, because on paper it looks simple: you know the work, you know the people, you've been chosen. In practice, it's often the most personally uncomfortable step up a career contains.

Why this transition is harder than it looks

The difficulty isn't competence. You were promoted because someone believed you could do the job. The difficulty is that every relationship on the team has to shift at once, and nobody tells you how.

Conversations that used to be easy become loaded. The colleague you'd happily vent to about a senior leader's decision is now someone whose performance you'll be assessing. The friend who covered for you once may expect you to return the favour. And someone on the team may have wanted the role themselves, which adds a layer of tension that rarely gets said out loud.

Meanwhile, you're also adjusting to a new relationship with the people above you. You're now expected to represent decisions you might once have grumbled about alongside the team. That in-between position — no longer quite one of them, not yet fully settled into the leadership layer — is where most of the discomfort lives.

Name the change rather than pretending it isn't happening

The most common mistake new managers make with former peers is trying to act as though nothing has changed. It's understandable; it feels kinder and less awkward. But everyone knows something has changed, and pretending otherwise tends to create confusion about where the lines now sit.

A better approach is to have a short, honest one-to-one with each person early on. Acknowledge that the dynamic is different, say what you value about working with them, and ask what they need from you in this new arrangement. For anyone who applied for the role, this conversation matters even more. You don't need to apologise for getting the job, but recognising their disappointment and making clear you value their contribution goes a long way.

Resist the urge to prove yourself too quickly

Many newly promoted managers feel pressure to establish authority fast — making visible changes, tightening processes, being noticeably firmer than before. The instinct is to show they're taking the role seriously. The effect is often the opposite: the team reads it as someone who's changed, and not for the better.

The advantage of promotion from within is that you already understand what works and what doesn't. Use that. Spend the first few weeks listening, asking questions you might previously have assumed you knew the answers to, and building a clear picture of what the team needs from its manager rather than what you think a manager is supposed to look like. Credibility with former peers comes more from fairness and good judgement than from assertiveness.

Be scrupulously fair

The fastest way to lose a team you've come up through is to be seen to have favourites. Former friends will notice if you're harder on them to compensate; others will notice if you're softer on your friends. Both erode trust.

It helps to be deliberate about consistency: the same standards, the same access, the same quality of attention for everyone. That might mean slightly less social time with the people you were closest to, at least for a while. It's not a rejection of those friendships; it's protecting them from the suspicion that they're the reason for decisions you make.

Handle the first hard conversation well

At some point, usually sooner than you'd like, you'll need to raise a performance concern or give critical feedback to someone who used to be a peer. This is the moment the team watches most closely, even if they don't know about it directly.

Prepare for it properly. Be clear about the specific issue, say it plainly and respectfully, and listen to their side. Avoid the temptation to soften it into nothing because of the history between you. Handled well, this conversation often does more to establish you as the team's leader than anything else in the first few months.

Find your own support

One of the quieter losses in this transition is that the people you'd normally talk things through with are now the people you can't talk to about certain things. That can be surprisingly isolating. It's worth deliberately building new sources of support — peers at your new level, a mentor further along, or a coach who can offer a confidential space to think.

Leaders who've made this move successfully tend to say the same thing: the first six months were harder than they'd expected, and they'd have benefited from support earlier. If you've recently stepped up to lead your old team, or you're about to, a short introductory conversation can be a useful place to think through what kind of leader you want to be from the start.
