Almost every new manager has the same moment. A few weeks into the role, someone on the team is missing deadlines, or being short with colleagues, or quietly doing half of what they used to. You know you need to say something. You also know they were your peer a month ago, and you’d rather do almost anything else.
So you wait. And the waiting makes it worse, because by the time you speak, the problem has grown and so has your frustration.
Talk sooner and smaller
The single most useful habit for a new manager is to raise things early, while they’re still small. “I noticed the report was late again this week. What’s going on?” is a two-minute conversation. The same issue left for three months becomes a formal one.
Small, early conversations also feel fairer to the other person. Nobody likes discovering in a review that something has bothered their manager for a quarter.
Prepare three sentences, not a script
You don’t need a speech. You need to be clear about three things before you walk in:
What you’ve observed, described as facts rather than character (“the last three updates were late,” not “you’re unreliable”).
Why it matters, in terms of the team or the work.
What you’d like to happen next.
Write them down. Saying them out loud once, to yourself or a friend, makes a surprising difference to how calm you sound in the room.
Clarity is kind. Vague feedback feels gentle in the moment and unfair later.
Then stop talking
The hardest part for most new managers is the silence after the first sentence. Resist the urge to soften, explain or fill the gap. Ask a genuine question, such as “How does that land?” or “What’s getting in the way?”, and let the other person answer.
Often you’ll learn something that changes the picture: a family situation, a confusing brief, a tool that keeps breaking. Sometimes you won’t, and that’s fine too. Either way, the conversation becomes a shared problem rather than a verdict.
Agree one next step
End with something concrete and a date. “Can we check in on Thursday and see how the new plan is working?” gives you both a reason to come back to it without it feeling like surveillance.
Afterwards, write a short note to yourself about what was said and agreed. If things improve, you’ll have a record of a conversation that worked. If they don’t, you’ll have the start of a fair process.
It gets easier, but only with practice
No one finds their first difficult conversation comfortable. The managers who get good at them aren’t braver than everyone else; they’ve just had more of them, earlier, about smaller things. Rehearsing with a coach before the real conversation is one of the quickest ways to build that confidence without practising on your team.
