Your best broker just became head of brokers. Your best engineer just became engineering manager. Your most experienced case-worker is now supervising the other three.
They’re about to have the hardest 12 months of their career. And there’s a reasonable chance you’ll lose them, or the team, or both, if nothing changes about how they’re set up to succeed.
This isn’t a dig at your choice. Promoting from within is usually the right instinct. But technical skill and management skill are two different jobs, and we almost never teach anyone the second one before they have to do it.
The trap
The job looked like: do the work, do it well, occasionally mentor someone.
The job is now: get work done through other people, deal with their friction, carry the emotional weight of the team, and protect them from the bits of the business that would grind them down. Oh, and you’re still expected to be the best technical operator in the room.
It isn’t a promotion in the shape most people imagine. It’s a career change dressed up as one.
The people who struggle hardest are often the most competent at the old job. They don’t want to let go of the work they’re good at, because that’s what got them here. So they try to keep doing their old job and bolt management on top. Twelve months later they’re exhausted, the team feels abandoned because nobody’s actually managing them, and someone quits.
What the job actually is (five shifts)
1. From doing to enabling. You succeed when the team succeeds. If the team’s output is the same as before and yours has dropped, that’s normal. That’s the trade.
2. From individual accountability to team accountability. Their mistakes are your mistakes now. That’s uncomfortable, but it also means their wins are yours, and your job is to build a team where the wins happen more often.
3. From task thinking to pattern thinking. The question stops being “how do I solve this?” and becomes “why does this keep happening, and what needs to change?”.
4. From peer to manager. This is the hard one. The people you used to complain about the boss with are now the people you have to make uncomfortable decisions about. You can still be warm. You can still be friendly. You cannot be their mate in the way you were before. That boundary has to shift, and both sides have to accept it.
5. From reacting to planning. IC work rewards speed. Management work rewards rhythm. A new manager who doesn’t install a rhythm (weekly 1:1s, fortnightly team check-ins, a standing planning conversation) tends to spend their days firefighting and wondering where the time went.
What to stop doing from day 1
If you promote someone on Monday and by Friday they’ve still got their entire IC workload, you’ve set them up to fail.
Strip at least 40% of their old work away before they start the new role. If you can’t, don’t promote them. Give them a senior-IC title instead and find someone else to manage.
Second: stop asking them to be the backstop for every technical question. If they’re the one pulled in for every tricky case, they’ll never develop the people beneath them, and the bench never deepens.
Third: stop rewarding them for doing the IC work. “That client is so lucky you’re still on their file” is a sentence that sounds like praise and functions like a trap. It tells them the old behaviour is still what you value most.
How to run a 1:1
It’s the single highest-return thing a new manager can do, and most get taught nothing about how.
- Thirty minutes, fortnightly minimum, permanent in their calendar.
- Their agenda, not yours. If they have nothing to discuss, that’s the discussion.
- Three questions, rotated:
- What’s in the way of you doing your best work?
- What’s going well that we should keep doing?
- What should I know that I don’t?
- Actions get written down. Both sides check back next time.
No status updates in a 1:1. That’s what the team meeting is for.
There’s a compliance angle too
Since December 2025, an untrained manager isn’t only a retention risk in Victoria. They’re a psychosocial hazard in the regulator’s language. Poor support from a manager, role ambiguity, unaddressed conflict: those are named hazards under the psychological-health regulations, and the duty to manage them sits with the business. The fix the law is pointing at is the same one this article is about: managers who know how to run a 1:1, give feedback, and catch the small things early. I’ve written about what those regulations mean for small businesses separately.
When to get help
A new manager doesn’t need to be sent on a five-day residential leadership course. Usually what they need is someone to sit in on their first couple of 1:1s, talk through the first few hard conversations, and give them a sounding board through the first six months.
That’s the work I do with Melbourne small businesses. Not management theory, but the specific coaching a new manager needs in the first year. When I led a team of 30 at CSIRO through significant organisational change we held 100% retention and resolved every conflict that came up, across four years. Not because I’m special. Because the skill can be taught.
If you’ve just promoted your best operator and you can feel the edges fraying, let’s talk about your team.
