Managing Former Peers: How to Lead the People You Used to Work Alongside
30 September 2026
On Friday you were one of the team, swapping complaints about the rota over lunch. On Monday you are the person who sets it. Managing former peers is one of the most awkward steps in any management career. The relationships that made you good at your old job are the very ones that now need to change. Handled well, the shift builds respect on both sides. Handled badly, it can sour friendships and weaken your authority within weeks. This article sets out practical ways to get it right, from the first conversation to the first difficult decision.
Why Managing Former Peers Feels So Hard
Most people are promoted because they excelled at their previous work, not because anyone checked whether they were ready to manage. A 2023 study by the Chartered Management Institute and YouGov found that 82% of managers enter the role with no formal management training. It also found that half of the workers who rate their manager as ineffective plan to leave within a year, against 21% of other workers. New managers rarely get a gentle start. Those who lead colleagues they know well get the least room for error.
Your former colleagues know your habits, your strengths and what you used to say about management. That familiarity can help you, but it also makes the change in your status more obvious to everyone, including you.
Expect a Mixed Reaction
Some team members will be pleased for you and ready to help. Others will wait to see what changes. One or two may resent the promotion, particularly if they applied for the role themselves. None of this is unusual. Treat it as information about where people stand, not as a verdict on your ability.
Reset the Relationship Early
The instinct when managing former peers is often to play down the promotion and hope nothing feels different. That is understandable but usually a mistake. Your team already knows things have changed and is waiting for you to say so. A better approach is to hold a short one-to-one with each person in your first week or two. Acknowledge the change openly, explain how you plan to work, and ask what concerns or ideas they have. Something as plain as “we have worked as equals for years, and now I am responsible for the team” is enough to start. Follow it with “so let’s agree how we work together”. That does more than weeks of hoping the awkwardness will pass.
Listening matters as much as talking here. People who feel heard early on are more likely to give you the benefit of the doubt when you make your first unpopular call. If you are also taking over the team’s direction, our guide to taking charge of an existing team shows how to diagnose what the team needs first.
Friendship and Boundaries
You can stay friendly with your team, but the closeness you had has to shift. You now assess their work and influence assignments, pay and progression. That sits uncomfortably alongside regular one-to-one lunches or shared grumbles about the organisation. Alison Green, who writes the Ask a Manager column, makes the same point. A professional boundary becomes necessary, which means no gossiping, no complaining about work and much less one-to-one socialising. Whole-team events remain fine.
In practice, managing former peers means keeping the team’s business confidential and avoiding private jokes about colleagues. It also means declining to be a sounding board for grievances you may later have to act on. Being warm and being professional are not opposites. The aim is to keep the first without losing the second.
When a Friend Expects Favours
The hardest test comes when a close friend assumes the friendship buys some latitude. It might be a relaxed deadline or first pick of the interesting work. Say kindly and directly that the same standards apply to everyone. Most friends will respect that more, in the long run, than a manager who bends the rules quietly. It also helps to build a new circle of peers among other managers. Then you are less tempted to seek support from the people you now lead.
The Colleague Who Wanted Your Job
If someone on the team applied for your role and lost, do not pretend otherwise. Speak to them privately and early. Acknowledge that they may be disappointed and ask what they want from their own development. Then act on the answer with real responsibility, such as leading a project or mentoring a newer colleague. A token gesture will not do. A capable rival who feels valued can become your strongest ally. One who feels ignored may spend their energy working against you.
When Resistance Becomes a Pattern
Occasional grumbling is normal. Repeated pushback, missed deadlines or being ignored is a pattern, and it needs a direct conversation. Describe what you have seen, ask what lies behind it and listen properly. Then state clearly what you expect and what will happen if nothing changes. If the problem continues, treat it like any other performance issue, with clear expectations, specific feedback and a fair process. Avoiding the conversation to protect a friendship usually damages both the friendship and the team.
Fairness Matters More Than Popularity
Your team will watch closely for signs of favouritism. Former peers spot it quickly because they know who used to be close to whom. Fairness is the real test of managing former peers. Share information with the whole team at the same time rather than in private chats with old friends. Apply the same standards to everyone, and explain the reasons behind your decisions, especially the unpopular ones. Your first hard decision, whether it concerns workload, a rota or a performance problem, sets the tone. Consistency at that moment tells people what kind of manager you intend to be.
Remember too that the team itself has changed. A new leader can push a settled group back towards uncertainty. It helps to recognise where your team sits in the stages of team development and adjust your style to suit. Expect some backwards movement at first. It does not mean you have failed.
Your First Thirty Days
A simple plan helps when you are managing former peers. In the first week, hold your individual conversations and tell your own manager how you plan to approach the team. In the second week, agree clear expectations with each person, in writing where that helps. By the third and fourth weeks, give your first honest feedback, both positive and constructive, and begin delegating properly. Handing some of your old tasks to others frees time for managing. That is now the main part of your job. Ask your own manager for advice before problems become serious. Seeking support early is a sign of sound judgement, not weakness.
Final Thoughts
Managing former peers works best when you name the change early and keep a professional boundary without turning cold. Speak openly with anyone who wanted your job. Stay consistent, so that everyone sees fairness in your decisions. Most new managers arrive untrained, so the difficulty is normal and not a personal failing. Some friendships will change and a few may fade, but many working relationships improve. The respect you earn by handling the shift honestly is likely to outlast the friendships you tried to keep unchanged.
