Monday morning, 9 a.m.
You walk into the meeting room you know by heart.
Same faces, same coffee mugs, same ritual jokes.
Only one thing has changed since Friday: you are now their boss.
And in the half-second of silence that nobody will ever mention, you can feel that everyone knows it, and that nobody knows yet how to deal with it.
Welcome to the most delicate transition there is: one where the terrain is familiar, but your position in the pack has just changed.
Why an internal promotion is harder than an external hire
Intuition says the opposite: you know the place, the files, the people…
Half the work is done, isn’t it?
That is precisely the reasoning that traps internal promotees.
A large share of managers promoted from within receive no support when they take up their role, precisely because the organization assumes they “already know everything”.
The result: they are left to run the most tactical race of their career alone.
Because what an internally promoted manager has to accomplish, no external manager ever has to do: change position in front of people who knew them somewhere else.
In running, there is a huge difference between joining a new pack and taking the lead of the one you were running in yesterday.
In the first case, nobody has any memories of you.
In the second, everyone does: your low moments, your strong opinions at the coffee machine, that project you criticized, that complicity with Julie against the decisions from “upstairs”…
You aren’t starting from zero. You are starting with a history.
It is an asset. And it is a debt.
The three traps that break the relationship (and your legitimacy)
- The buddy trap: changing nothing
“I’m still the same, nothing changes between us.”
It is the most tempting and the most untrue sentence of day one.
Something has changed: from now on you will evaluate, arbitrate, allocate, and sometimes refuse. Pretending otherwise reassures nobody; it simply delays the moment reality catches up, usually at the worst possible time: the first difficult performance review, the first no.
Teams don’t ask that nothing change.
They ask to know what is changing. - The sheriff trap: changing everything
Conversely, some promotees overplay the break: a more distant tone overnight, calculated distance, quick decisions to “mark their territory”.
In racing, it is the runner who, barely in the lead, accelerates sharply to shake off their former group. The effect is immediate: the pack closes ranks, and former partners become the first opponents.
Sudden coldness is experienced as betrayal.
And in a team, betrayal is paid for over a long time. - The implicit-debt trap: inherited favours
This is the sneakiest one.
Marc covered for you last year when you were swamped.
Sophie was your ally in every debate.
And there is that colleague who wanted the job and didn’t get it.
Each of these relationships carries a silent expectation: preferential treatment, continued loyalty, or on the contrary a score to settle that you need to watch for.
As long as these debts remain implicit, they steer your decisions without your knowing.
And everyone can see it, except you.
Changing position in the pack: the method
Name the change, once, but clearly.
In the first two weeks, set up a one-on-one conversation with each team member. Not a solemn group meeting: a face-to-face exchange where you say explicitly what is changing and what isn’t.
Something like:
“Our relationship matters to me and it continues. My role, however, is changing: I’ll have to make decisions that won’t always suit you, and I’d rather we say so now than discover it in three months.”
That sentence costs thirty seconds of discomfort. It saves months of misunderstanding.
Deal with the disappointed candidate first.
If someone on the team was aiming for the job, that is your priority conversation, not the one to put off.
Acknowledge the situation without apologizing for having been chosen:
“I know you wanted this job, and I understand my appointment is hard to take.”
Then open up the future: what interests them, what role do they want to play, how can you support their development?
A disappointed candidate who is ignored becomes an underground opposition.
A disappointed candidate who is respected often becomes a solid ally.
Make your rules of the game visible, and the same for everyone.
Your best protection against accusations of favouritism (or of settling scores) is an explicit framework: how you allocate files, how decisions are made, how you give feedback...
When the rules are visible, nobody needs to scrutinize yesterday’s friendships to guess tomorrow’s decisions.
And stick to them all the more scrupulously with those who were close to you: that is where you will be watched.
Renegotiate the complicities.
With some colleagues you had backstage rituals: confidences about management, shared irony about decisions from upstairs.
You can no longer take part, you are “upstairs” now.
But there is a difference between withdrawing from those conversations and sanctioning them.
Withdraw with a smile, not a sermon:
“You know I can’t say that with you anymore, but tell me instead where you’re at on your file.”
Humour that acknowledges the new situation is better than distance that denies it.
Accept the relational desert crossing.
It needs to be said honestly: for a few months, you will be lonelier than before.
No longer quite part of the team, not yet settled among your fellow managers.
This is the time to build your new pack: your peer managers, a mentor, a coach...
It isn’t a luxury; it is your refuelling for a stretch of the race that is, by definition, run without your former companions.
And the race is longer than you are told
One last word, because it changes everything: the transition from former colleague to recognized manager isn’t decided in the first 90 days.
In the first weeks, everyone makes an effort, you as much as them.
The real test comes later: the first annual review of someone who used to be close to you, the first conflict to arbitrate between two friends, the first unpopular decision to own alone in front of the group...
Those moments happen between the fourth and the twelfth month, right in the zone where support has stopped and where, as we saw in a previous article:
most transitions are won or lost.
So your relationship with your former colleagues isn’t protected by avoiding difficult moments. It is built in the way you get through them, one by one, over the whole distance.
The question is not “How do I stay friends with them?” nor “How do I assert myself?”.
It is: “What kind of leader will they want to follow in a year, knowing exactly who I was before?”
Frequently asked questions about taking on a role through internal promotion
Should you keep your work friendships when you become your friends’ manager?
Yes, but they need to be renegotiated, not kept exactly as they were.
The relationship can remain warm and sincere.
What needs to change is its scope: no more confidences about management decisions, no more preferential treatment, and greater vigilance about fairness as perceived by the rest of the team.
The friendships that survive a promotion are those in which this new scope has been openly named.
How should I react if a former colleague tests my authority in front of the team?
Never settle the situation in the heat of the moment in front of the group: you would lose either your composure or the other person’s face, and both would cost you dearly.
Speak to the person privately within 24 hours, separating the relationship from the behaviour:
“Our history doesn’t change the fact that what happened in the meeting isn’t acceptable.”
The speed and consistency of your reactions matter more than their severity.
What if I feel the team has been keeping me at arm’s length since my promotion?
It is an almost inevitable phase, not necessarily rejection: the team is recalibrating the relationship too, and some distance is a sign that it has understood your role has changed. Keep being predictable, fair and present, without forcing a return to the old complicity.
If the distance persists beyond a few months or turns into hostility, seek a direct conversation with the people concerned.
And outside support for yourself, because this in-between period is when new managers wear themselves out the most.
Do you prepare differently for an internal promotion than for an external hire?
Yes, almost point by point.
> The external hire must first decode unfamiliar terrain, whereas the internal promotee must first reframe familiar relationships.
> The external hire benefits from a presumption of legitimacy (“she was recruited for this”), whereas the internal promotee must establish theirs in front of people who remember them as an equal.
Each race deserves its own plan: that is the subject of our article on internal mobility and external hiring.
