On Friday you were one of the team. On Monday you are their manager. The people you sat with, complained about leadership with and went for lunch with now report to you. Someone in the group applied for the same job. Everyone is quietly waiting to see whether you will change.
Being promoted over your former peers is one of the most common leadership transitions, and one of the most underestimated. It looks simpler than joining a new organisation, because you already know the people and the work. In practice it is often harder, because the relationships have to change while the people stay the same.
This guide covers why the transition is difficult, what needs to change and what doesn’t, and how to handle the first conversations, including the one with the person who wanted your job.
Why leading former peers is hard
The difficulty sits on both sides of the relationship.
- For you, there is a pull to stay liked. Decisions that would be straightforward with strangers feel personal with friends, and it can be tempting to avoid them.
- For your team, there is uncertainty. They don’t yet know which version of you they’ll get: the colleague they knew, or someone who has “gone over to the other side”.
- For the organisation, there is a test. Your own boss is watching to see whether you can make the shift from colleague to leader, and how quickly.
New leaders tend to go wrong in one of two directions. Some change too little, and the team never quite accepts their authority. Others change too much, become distant overnight, and lose the trust that made them a good choice in the first place.
What changes, and what doesn’t
It helps to be clear, first with yourself, about which parts of the relationship need to change.
| Part of the relationship | Before | Now |
|---|---|---|
| Information | You shared views and frustrations freely | Some things you know can’t be shared, and some views need more care |
| Decisions | You influenced decisions | You make them, and you are accountable for them |
| Feedback | Optional, between equals | Part of your job, including when it’s uncomfortable |
| Fairness | Friendships were your own business | Closeness to some people can look like favouritism to others |
| Respect and warmth | Mutual | Unchanged. This is the part to protect |
The last row matters most. You don’t need to stop being friendly or human. You need to be consistent and fair, and to make decisions that a former colleague might not like.
Your first conversations
Meet each person individually in your first week, before any group meeting sets the tone. These are conversations, not announcements. Most go well when they cover four things:
- Acknowledge the change honestly. Something like: “This is a bit different for both of us, and I’d rather talk about it than pretend it isn’t.”
- Ask what they need from you now. Their answer will tell you more about how they’re feeling than any question about the work.
- Say what won’t change. Respect, openness, the way you treat people.
- Be honest about what will. You’ll be making calls they may disagree with, and you’ll explain your reasoning when you do.
Keep it short and genuine. People will remember the tone of this conversation far longer than the content.
The colleague who wanted the job
If someone in your team applied for your role, talk to them first and talk to them privately. They may be disappointed, embarrassed or angry, and they may also be one of your strongest people.
- Acknowledge it directly. Avoiding the subject makes it bigger.
- Recognise their strengths specifically, and mean it.
- Ask what they want for their career, and whether you can help them get there.
- Give them real responsibility early, if they are capable of it. This often turns a rival into an ally.
- Accept that some people will need time, and a few may decide to leave. That is their choice to make.
Setting boundaries without becoming distant
Boundaries are what make fairness possible. The ones that matter most are usually these:
- Confidential information. Decide in advance what you will and won’t discuss, especially about pay, performance and other team members.
- Venting about leadership. You are now part of it. You can still disagree with decisions, but not with your team in the way you used to.
- Social time. You don’t need to stop socialising. Be even-handed about who you spend time with, and be aware that conversations over a drink are still conversations with your manager.
- Old alliances. If you were close to some colleagues, take particular care that they aren’t seen to get easier treatment.
Making the first difficult decision
Sooner or later you will have to make a call that someone in your former peer group doesn’t like: a performance conversation, a change to how work is allocated, a no to a request. How you handle the first one sets the pattern for everything after it.
Make the decision on its merits, explain your reasoning, listen to the response, and don’t apologise for doing your job. Most people respect a fair decision made openly far more than a popular one made to keep the peace.
Your first team meeting
After the individual conversations, bring the team together. The first meeting sets the tone for how you will lead, so keep it purposeful and short. A simple structure works well:
- Acknowledge the change. Say plainly that this is new for everyone, including you.
- Share what you’ve heard. Summarise the main themes from the one-to-ones without attributing comments to anyone.
- Say what you value about how the team works, and what you intend to keep.
- Set out how you’ll work with them. When you’ll meet, how decisions will be made, how they can raise concerns.
- Name one or two early priorities, ideally ones the team raised themselves.
- Ask for their help. Not as a formality: ask what they need you to start, stop or continue.
Avoid announcing big changes in this meeting. If you already know some are coming, say that you’ll share more once you’ve finished listening, and give a date.
When a former peer is underperforming
This is the situation new leaders dread most, and the one they most often put off. The longer it waits, the more the rest of the team notices, and the more your authority suffers. Handle it the same way you would with anyone else, with a little extra care about tone.
- Be clear on the facts first. What specifically isn’t meeting the standard, and since when?
- Have the conversation privately and soon. “I want to talk about something that’s difficult, partly because we’ve worked together a long time.”
- Describe the gap, not the person. Focus on the work and its effect on the team.
- Listen to their side. There may be a reason you didn’t know about as a colleague.
- Agree what needs to change and by when, and what support you will give.
- Follow up as you said you would. Consistency is what makes the conversation credible.
Some new leaders worry that this will end the friendship. In practice, most people respect a fair, direct conversation far more than months of avoidance followed by a sudden escalation.
Looking after yourself in the transition
Leading former peers can be lonely in a way people rarely mention. The colleagues you used to share frustrations with are now the people you manage, and your new peer group may not feel like home yet. That is normal, and it eases with time, but a few things help:
- Build relationships at your new level. Your new peers are facing similar challenges and are often glad to compare notes.
- Find someone outside your reporting line to think out loud with, such as a mentor, a former manager or a coach.
- Keep some friendships outside work. You need places where you are not anyone’s manager.
- Expect some discomfort. Feeling awkward in the first few months is a sign that the relationship is changing, not that you’re doing it badly.
How long the transition takes
Most new leaders expect the awkwardness to pass in a few weeks. In my experience it usually takes longer, often three to six months, and it tends to move through recognisable stages:
| Stage | What it feels like | What helps |
|---|---|---|
| First weeks | Polite, slightly stiff, everyone watching for change | Individual conversations, consistency, no sudden moves |
| First difficult decision | A test of whether you’ll lead or stay a colleague | A fair decision, explained openly |
| Settling | People stop referring to how things used to be | Delivering on what you said you’d do |
| Established | The team relates to you as their leader without thinking about it | Continuing to invest in the relationships |
If you are still finding it hard after six months, that is worth talking through with someone outside the team. It usually means one specific relationship or decision is holding things back, and it can be addressed.
If your promotion is also a step up to director level, The First 90 Days as a New Director sets out a practical plan for your first three months.
Common mistakes
- Trying to stay one of the team. It feels kind, but it leaves your team without the leadership they need.
- Overcorrecting into distance. Suddenly formal behaviour feels like rejection to people who knew you well.
- Avoiding the conversation with the unsuccessful candidate. The longer it waits, the harder it gets.
- Changing everything to prove a point. You don’t need to show you are different from your predecessor in week one.
- Going it alone. Find someone outside the team to talk to: a mentor, a peer in another function, or a coach.
Plan your first conversations
Use this to prepare for your one-to-ones. The first row shows an example.
| Team member | Our relationship before | What they may need from me now | First conversation |
|---|---|---|---|
| Applied for the role | Close colleague for four years | Recognition, a clear future, real responsibility | Day one, privately |
