When Yesterday’s Colleague Becomes Today’s Manager
Leadership in Practice · Leadership

Promotion changes the title immediately. Relationships, boundaries and expectations take longer to catch up.
On Friday, you are part of the team, working the same shift, dealing with the same problems and probably complaining about some of the same things. On Monday, you may be approving the rota, allocating sections, checking standards and occasionally saying no to someone who, a few days earlier, was simply a colleague.
It is a familiar transition in hospitality. A waiter becomes a supervisor. A Chef de Partie becomes a Sous Chef. A receptionist becomes an Assistant Front Office Manager. The promotion can happen in one conversation. The relationship with the team does not change that quickly.
The Team Remembers Who You Were Before the Promotion
A new title does not erase what came before it. Former peers remember the conversations you had when you were on the same level, the rules that frustrated you and the managers you disagreed with. They also know how you behaved when the final responsibility belonged to somebody else.
That history does not need to become a problem. Pretending it no longer exists usually creates more awkwardness than acknowledging it.
Some newly promoted managers become unusually formal or strict because they feel they must prove they are now in charge. Others avoid difficult conversations because they do not want former colleagues to think the promotion has changed them. Neither response deals with the real transition.
You do not need to become a different person. You do need to accept that the same behaviour can carry different weight once you are responsible for decisions that affect the team.
Small Decisions Establish the New Relationship
The first tests are usually ordinary. A former colleague arrives late. Someone expects a preferred shift because you have always been close. A mistake needs correcting and the person involved assumes the conversation will be easier because you used to work side by side.
Those moments are uncomfortable because everyone understands the new dynamic. The temptation is either to let something pass or to react more strongly than necessary to prove there are no favourites.
What the team needs instead is a clear standard and a manager who applies it without turning the relationship into the issue. Fairness does not require identical answers in every situation. People have different roles and circumstances. It does require reasoning that can be explained and defended, especially when a decision involves the people you were closest to before the promotion.
Familiarity Needs New Boundaries
Before a promotion, always taking your break with the same two colleagues may be completely unremarkable. Afterwards, other people may read it differently. The same can happen with jokes, private conversations, shift requests or the way mistakes are handled.
This does not mean a manager should become distant or stop having friends at work. Hospitality rarely works that way. People spend long hours together, often under pressure. In resorts and remote destinations, colleagues may also live in the same environment, eat together and share far more of daily life than they would in many other industries.
An artificial wall between manager and team is neither realistic nor particularly useful. But personal closeness cannot become a private exemption from professional standards.
Sometimes a short conversation with a close colleague prevents a great deal of confusion later: the relationship has not disappeared, but there will now be situations in which a decision has to be made as a manager. That does not mean withdrawing from the friendship; it simply makes the responsibility of the new role clearer.
The First Difficult Conversation Matters
Sooner or later, a newly promoted manager has to correct someone who used to be a peer. Delaying that conversation because the issue seems small or the relationship feels uncomfortable usually makes the next one harder.
The useful approach is to keep the conversation about the work: what happened, what was expected, what needs to change and whether something is preventing the standard from being met. There is no need to perform authority or apologise for exercising it.
The Journal has previously covered how to correct a team member without humiliating them. In this transition, the additional risk is ambiguity. A former peer should not have to guess whether friendship changes the standard, and the rest of the team should not have to guess either.
Do Not Perform Authority
Another common mistake is imitation. A person steps into leadership and begins borrowing the language, tone or habits of managers they have worked under, including behaviours they did not particularly respect when they were on the other side of the rota.
Being promoted does not mean becoming a smaller version of the person above you. The technical skills that helped earn the promotion are only part of the new job. The rest has to be learned through decisions, conversations and the consequences that follow them.
You may communicate differently from your predecessor. You may explain decisions more clearly, notice tensions they overlooked or discover that something you once criticised makes more sense now that you have to make the decision yourself. That is part of learning the role.
The objective is not to look like a manager, but to become someone the team can rely on when decisions have to be made.
The Team Is Adjusting Too
The person who was promoted is not the only one making a transition. Someone on the team may be genuinely pleased. Someone else may wonder why they were not chosen. A few people may test the new boundaries, while others simply wait to see what changes.
Most of that does not need a dramatic response. People need time to see how the new manager behaves when service becomes difficult, when two people ask for the same day off, when a friend makes a mistake or when an unpopular decision has to be made.
A job title can be assigned immediately. Credibility develops through the ordinary decisions that follow it.
An Old Relationship With a New Responsibility
Internal promotion has real advantages. The person already understands the operation, knows the team and recognises many of the small problems that an external manager might take months to discover. Familiarity is an asset, but it also means yesterday’s colleagues already know where the new manager is strong and where they are not.
There is little value in trying to become somebody else after the promotion. The transition tends to work better when little is forced: relationships remain recognisable, expectations become clearer and decisions gradually show what the new responsibility means in practice.
Over time, the team pays less attention to the fact that a colleague was promoted and more attention to whether that person can be trusted to manage fairly, consistently and well.
