Work & pressure
How do I supervise people who used to be my coworkers?
Start a new supervisory role with clear expectations, fair follow-through and private conversations instead of sudden distance.
Name the change without performing a new personality
You can acknowledge that the role has changed without pretending you were never part of the team. A simple opening might be: “I now have responsibility for scheduling and follow-up. I want us to be clear about what you can expect from me and where decisions sit.”
Confirm your actual authority with your manager before promising changes. Write down what you can decide, what needs approval and where employees should take questions you cannot answer.
Make the work expectations visible
Choose a few concrete expectations relevant to the job: how work is handed over, how problems are raised, and when follow-up happens. Describe observable behaviour instead of asking everyone to have a better attitude.
Apply expectations consistently, while following the organisation’s policies and any applicable arrangements. Fairness does not mean guessing about individual circumstances or ignoring approved accommodations. When uncertain, consult the appropriate manager or HR contact.
Have awkward conversations privately
If a former coworker keeps treating an instruction as a joke, speak privately and be specific. “When I asked for the handover update, you replied that I was acting important. I need the update by the agreed time. Is there something about the task we need to clarify?”
Let them explain. Keep the discussion about the work and the next step. Avoid settling old disagreements or proving authority in front of the group. If the matter requires a formal process, follow that process rather than improvising discipline.
Close the loop and protect confidences
At the end of a conversation, summarise the action, owner and follow-up date. Make factual notes through approved systems, limiting them to what is necessary for the role. Do not keep gossip or sensitive employee information in an informal shared notebook.
A useful first-week check is: does each person know how to reach you, what you are responsible for and when you will follow up? Familiarity can help you understand the work. Clear boundaries help you handle the new responsibilities that come with it.
