Managing Former Peers After a Promotion: A 30-Day Plan

On Thursday you were at lunch with your teammates, laughing about the last leadership meeting. On Sunday morning the announcement went out: you got the promotion. Now you walk past your closest friend's desk and he drops his voice a little, then smiles a beat too long.

You have not changed in three days, but your place among them has. And nobody trains you for this particular promotion: leading the people you used to be one of.

This article is a plan for your first thirty days, ending in a week-by-week schedule you can use. Along the way we say what the research supports and what is plain practical judgment.

Why is this promotion harder than most?

An ordinary promotion moves you somewhere new, so you build your reputation from zero. Here the place and the people are the same, and the rules of the relationship have flipped: the person who used to ask your opinion now waits for your decision, and the one who used to joke with you now watches what he says.

That is why Michael Watkins, author of The First 90 Days, treats leading former peers as a challenge of its own. In his 2009 book Your Next Move it is one of eight major career transitions.

The numbers point the same way. In a 2014 white paper, researchers at the Center for Creative Leadership (CCL) analysed answers from 295 first-time managers who attended one of its training programs between May 2012 and December 2013. Each had written, in their own words, their three most critical leadership challenges. The most common, named by 59.3%, was adjusting to people management and displaying authority, which the paper defines to include moving from coworker to superior and earning respect while keeping good relationships.

Mind the limits: these are self-reported answers from managers in a training program, about two-thirds American (65.8%), not a survey of every workplace. Still, they tell you that what you feel is common among new managers, not that you are unfit for the role.

Linda Hill of Harvard Business School goes deeper. Her book Becoming a Manager follows nineteen new managers through their first year, and its publisher sums up the idea this way: the move from employee to manager is a profound psychological adjustment, a true transformation, not just new tasks. What is asked of you is not only new tools but a new answer to who you are inside this team.

The CCL paper also describes a familiar scene: the lunchtime grumbling about the boss carries on, but now you are the subject, and you are not in the room. So if conversation dies when you walk in, that is part of the transition, not a verdict on you.

The first one-on-one with each colleague

Two sources agree on the first move: do not open with a big meeting or a list of new rules. Sit down with each person separately. Liane Davey, writing in Harvard Business Review in 2015, says the first step is to meet each team member one-on-one. CCL adds that the meeting should be booked as soon as you are promoted and be about the employee: what motivates them, what they like about the job, how they like to be led, and what worries them. Only after listening do you share your picture of the team and where they fit.

It works for a practical reason. In a group everyone plays their usual part; alone with you, someone may say what they have not said in years. It is also your first deposit in the trust account that The Blind Manager devotes a chapter to, "the bank account of relationships".

A suggested opening

"I know this feels strange for both of us, and I would rather say so. My respect for you and our history here will not change. What will change is that some decisions are now mine, and the standard will be the same for everyone, including you. Before I suggest anything, I want to hear from you."

Five questions to ask

1. What do you like about how we work now that you would not want to change?
2. What is holding you back right now that I could remove?
3. How do you prefer to get feedback: right away or after time to think, spoken or written?
4. Where do you want to be in a year, and what is missing to get there?
5. What worries you about this change?

Steer clear of three things in this meeting: promising what is not in your hands, such as raises; criticising your old boss or another colleague, since it tends to get back to them; and asking for loyalty instead of candour.

Friend or boss: where do you draw the line?

Why does friendship get complicated once you are the boss? Julianna Pillemer and Nancy Rothbard of the University of Pennsylvania offer a useful explanation in a 2018 theoretical paper in the Academy of Management Review. In their framework, friendship rests on informality, free choice, communal norms and socio-emotional goals, while organizations rest on formal roles, imposed constraints, exchange norms and practical goals. The two can be fundamentally at odds, and a promotion puts you right on the seam. A small favour between you and a friend may be innocent kindness, yet the rest of the team reads it as favouritism. In an interview with Knowledge at Wharton (2018), Rothbard says others usually assume the subordinate friend is getting favoured, which is why she advises being vigilant about how things look and making your decision criteria explicit.

So where do you stand? Executive coach Muriel Wilkins, on the Coaching Real Leaders podcast from Harvard Business Review (November 2025), separates friendliness from friendship: aim for pleasant, relationship-building interactions with everyone, not to be everyone's friend. She frames it as both/and: keep the relationship and drive the work at the same time.

CCL says plainly that you can still be friends, but you may lose some friends and need to be aware of that. It sets three conditions: clear expectations from the start, no preferential treatment for friends on bonuses, raises, promotions, support or resources, and awareness that knowing your friends better may lead you to give them more time and support than others without meaning to.

Here is a practical translation. It is our own judgment, not a research result:

• Stays the same: coffee, jokes, shared memories, asking about his family, standing by him through a hard personal moment.
• Needs care: talking about other colleagues, your complaints about senior management, information not yet announced, and always going out with the same small circle.
• Changes: decisions about assignments, evaluations, raises and schedules. All of them follow one stated standard.

Before any decision that touches a friend, ask: if I explained this in front of the whole team, would it look fair by the same standard? Fairness nobody can see might as well not exist.

Do not leave it to guesswork. Tell your close friend something like: "At work I will treat you the way I treat everyone, and that does not make you less important to me. If you ever feel I am being too careful or unfair, tell me straight." A sentence like that costs a minute and saves you both months of interpretation.

And beware the opposite mistake: running from everyone. A 2009 Globe and Mail review of Watkins's book describes a newly promoted marketing director who could not decide whether to sit with her new peers or her former team, so she fled and ate elsewhere. Watkins counsels that this was the wrong move. Better to greet your new peers, say you look forward to working with them and will meet each one, and then sit with your former team without guilt.

The colleague who competed for your job

Someone on your team may have applied for the same job and lost. Davey notes that a promotion means disappointment for those who did not get it, and that the balance of power between you shifts for good. No magic phrase erases the feeling, but you can limit the damage. These steps are our own practical judgment, not a research result:

1. Go to him first. Talk privately on day one, or before the wider announcement if you can. Avoiding him leaves room for him to read the silence however he likes.
2. Name the situation without drama. "I know you wanted this role, and I understand the news is heavy."
3. Do not apologise for the promotion or play it down. Apologising weakens you; playing it down insults him.
4. Ask what he wants. Then offer one concrete thing you can deliver within a month: a project, exposure to senior leaders, a written development plan. General promises are forgotten; a concrete step is believed.
5. Separate his feelings from his behaviour. He is entitled to be upset; he is not entitled to undermine decisions in front of the team. If it happens, talk to him privately with a specific example, not a sweeping "you always object".

Do not make him your permanent adviser to buy his silence, and do not sideline him from important work. Accept that some people need longer and some will decide to leave. That is not necessarily your failure; it is his decision, so leave the door open.

Your first decision: do not change everything

Amy Gallo, in Harvard Business Review in 2012, framed your dilemma: how to establish credibility and authority without seeming to let the promotion go to your head. The usual temptation is to prove yourself with a big, fast change, but the best signals we have point the other way.

Watkins recommends small early wins that build credibility, according to a 2003 Publishers Weekly review of The First 90 Days. And Herminia Ibarra found, in a qualitative study of consultants and investment bankers moving into more senior roles (Administrative Science Quarterly, 1999), that adapting to a new role means trying out "provisional selves": you watch role models, test a style, then judge it against your own standards and other people's feedback. The idea carries over despite the different field: you do not have to know how to be a manager on day one. You have to experiment and listen.

So give your first decision a simple test: it should fix a pain you heard about yourself in the one-on-ones, and be small enough to reverse. Cancel a weekly meeting that helps nobody, or cut an approval step that stalls work for a week. Explain why, and call it a trial you will review in two weeks.

In month one, hold off on anything that touches people or their positions: reshuffling roles, flipping schedules, replacing procedures your team built itself. Those decisions need a balance of trust you have not built yet. Wilkins suggests a one-week experiment: list the people you manage, try a more individual style of communication with each while your standards stay fixed, and watch what happens.

Your first 30 days

We have gathered the above into a schedule you can copy into your notebook. It is a suggestion, not a proven recipe, so adjust it to your team's size and your kind of work.

Where to go from here

Do not wait until you feel ready. This week, sit down with your first colleague, open with a question rather than a speech, and notice how the mood between you shifts in ten minutes. The friendships that survive a promotion are often the ones that became more candid, not the ones that ignored what changed.

If you want to go deeper, The Blind Manager has a chapter on "the bank account of relationships" and another on handling hard conversations, and it closes with a summary of 20 principles for the sighted manager. The book is in Arabic, and its page offers a free abridged audio edition in Egyptian Arabic.

And a thirty-day plan asks for a small daily commitment to yourself before it asks anything of your team. That is the subject of Istiqala: why we keep promises to others and break them to ourselves.
