From Peer to Manager: How to Lead a Team You Used to Work In

Why is promotion from within harder than it looks?

Many employees are promoted because they excel at their technical work, then find themselves judged on something entirely different: other people’s results. In a 2023 study by the Chartered Management Institute (CMI), 82% of managers who had moved into management said they had not received proper management and leadership training. CMI calls them “accidental managers”, promoted because they are good at their job, popular or simply available. ^[2]

The difficulty grows when the team is the one you used to be part of. The relationships already exist, some colleagues may have applied for the same role, and every decision you make is read through your shared history. The common mistake goes one of two ways: a manager who avoids the awkwardness and leaves everything as it was, or one who over-asserts authority and loses the trust that was their main asset.

Start with your manager: where does your authority end?

Before you address the team, sit down with your own manager and agree in writing three categories of decision: what you decide alone, what you decide after consultation, and what you escalate. This usually covers approving leave and overtime, allocating work, performance appraisal, nominations for training and handling misconduct.

Ask too about the open files you have inherited: promises made by the previous manager, performance cases under review and pending requests. Discovering these from the team itself puts you on the back foot from day one. Where your organisation has an approved delegation of authority matrix, make it your first reference instead of unwritten custom.

How do you announce the change to the team?

You do not need a formal speech. A short meeting is enough to explain what has changed and what has not: where requests go, who approves what, and which working standards you will follow up. Say clearly that important decisions will rest on criteria everyone knows, not on anyone’s closeness to you.

Avoid announcing major procedural changes at this meeting. You have not yet gathered enough information as a manager, and the team is watching to see whether you will listen before you decide.

Three messages are usually enough at this meeting:

• What stays: current priorities and deadlines continue until you review them together.
• What changes: the route for requests and approvals, and who to go to for each kind.
• What happens next: a one-to-one with every member in the first few weeks, then a team review of what you heard.

If a colleague applied for the same job, do not mention it in front of the team; give them an early, separate meeting instead. Acknowledging the situation privately preserves their dignity, while ignoring it in public turns it into a subject for whispers.

One-to-ones: what should you ask your former peers?

An SHRM article advises meeting each former peer individually to explain how the relationship is changing, and argues that the direct approach is better than leaving the person to infer the change from a sudden coolness. It suggests letting employees voice their feelings and reservations in these meetings, because that makes the awkwardness easier to move past rather than letting it build up. ^[1]

Practical questions for these conversations:

• What is working well in the team and should not change?
• What obstacle slows your work that I can remove?
• How do you prefer to receive feedback on your work?
• Which responsibility or skill do you want to develop this year?

Do not take silence as agreement. According to CIPD, employees may stay silent when they judge that the risks of speaking up outweigh the benefits, power dynamics strongly affect whether they speak, and genuine two-way communication requires managers to listen to feedback and act on it. ^[4] The power relationship between you and your colleagues has just changed, so show in practice that candid feedback is well received.

Old relationships: friendship, fairness and sensitive information

Nobody expects you to end your friendships, but you are expected not to give them privileges. The SHRM article stresses that the team needs to know there will be no preferential treatment in pay, promotion, support or resources, and that transparency and fairness are what protect a manager promoted from within. ^[1]

Three practical rules:

• One channel for requests: leave, exceptions and nominations go through the same route for everyone, even when the request comes up in a friendly chat.
• Information by role: some of what you now know about salaries, appraisals or upcoming decisions can no longer be shared. If a former peer asks about it, explain who owns it and the formal route for requesting it.
• Record decisions that matter: write down the decision and the reason, so any employee can understand it without reference to how close they are to you.

If your organisation has a conflict-of-interest policy, check it in cases involving a close friend or relative, and involve your manager where needed.

Hypothetical example

A former peer asked the new manager, by private message, to nominate him for a course with limited places. The manager neither refused nor agreed; instead he published the nomination criteria to the whole team and asked everyone interested to apply through the same channel. Selection rested on how relevant the course was to each applicant’s duties and how soon they could apply it, and the manager told those not selected when the opportunity would come round again. He kept the relationship and applied a standard anyone could review.

Managing performance with people who were your equals

The hardest moment for a new manager is the first critical feedback to a former peer. The answer is to move the conversation from the person to the work: clear agreed objectives, specific recent facts, an expected output and a follow-up date. Do not hold back the first piece of feedback until the annual review to protect the relationship; delay only makes the feedback heavier and more of a surprise when it finally comes.

CIPD explains that the manager’s role in performance management is to help employees connect their objectives to organisational goals, give feedback that motivates and supports improvement, and hold people to account, and that objectives work best when they are specific and stretching. At its best, it says, performance management is a regular, open and supportive two-way discussion, not just an annual review. ^[3]

Watch out for a common trap: carrying on doing the technical work yourself because you are good at it. This holds the team back and drains your time. The SHRM article advises delegating work according to each person’s skills and interests and giving them a degree of autonomy. ^[1]

What is different in Gulf workplaces?

Many teams in the region are spread across branches or field sites, or include supervisors with overlapping authority. In that case, make clear who approves and who runs day-to-day work, so employees are not caught between conflicting instructions. Make request and feedback channels available to staff who work away from the office, not only to those who pass your desk.

In government and semi-government bodies, many decisions are tied to approved procedure manuals and delegation matrices, so check them before promising anything. And do not manage the transition alone: the SHRM article recommends that new managers build a peer group of other managers, ask HR to pair them with a mentor, and look for resources outside the organisation if their own does not provide them. ^[1]

Conclusion

Promotion from within gives you knowledge that an outside hire does not have, but it puts your relationships to the test. Agree your authority first, listen to each colleague individually, and make fairness visible in every request, opportunity and appraisal.
