Managing people

Your best technician is now your worst manager

By Nichola Morgan MCIPD · Reviewed 4 September 2026

Most businesses promote great people into management and then leave them to figure it out. It is the most common people decision a growing business makes, and quietly one of the most expensive.

I see this more than almost anything else, and it very rarely looks like a problem at the time it happens.

How it happens

Someone is very good at the work. They're reliable, they know the systems better than anyone, clients ask for them by name, and they've been there long enough to understand how things really run rather than how the handbook says they do.

A management role comes up. Or, more often in a growing business, one gets created around them, because the team has reached the size where somebody has to be in charge of it and this is obviously the person.

They take it. Everyone is pleased. It reads as a reward, and it is meant as one.

What nobody does is sit down with them and say out loud that the job has changed. They were promoted for being excellent at something they will now do considerably less of, and asked to be good at something entirely different, starting the same Monday morning.

What it looks like six months later

The pattern is remarkably consistent, whatever the sector.

They do the work themselves. It's faster, it's what they're good at, and it genuinely feels like helping the team out. Meanwhile nobody underneath them is learning anything, and they are answering emails at nine in the evening because the actual management part has been pushed to the end of the day.

They avoid the difficult conversation. They were a peer three months ago. Telling someone their work isn't good enough, when the two of you were moaning about the same rota in January, is genuinely hard — and nobody has ever shown them how it's done. So it gets left, and then left again, and by the time it's raised it has grown into something much bigger than it needed to be.

Everything escalates to you. Not because they're incapable, but because nobody has told them where their authority stops. If you don't know whether a decision is yours to make, asking is always the safe option. Every single time. And the owner who wanted to free up their week finds they've added a daily check-in instead.

Good people start quietly looking. This is the one that costs real money, and it is almost always the last symptom anyone connects back to a promotion made eight months earlier.

What's usually underneath it

Almost never capability. In my experience it's three things that nobody has said out loud.

They don't know what the job actually is. "Manage the team" is not a description of anything. What are they responsible for deciding? What has to come to you? What does good look like in six months? A surprising number of first-time managers are working entirely from guesswork about the answers.

Take Sam, promoted to run a team of five. Sam thinks the job is making sure the work gets out of the door — because that's what Sam was always measured on. The owner thinks the job is developing the five people. Neither has ever said this to the other, and both are quietly disappointed six months later.

Nobody has shown them how to have a direct conversation. Most people have only ever seen this done badly. Either it's avoided entirely until it comes out sideways, or it's delivered as a telling-off. Almost nobody has seen the version in between — the one that's specific, kind, about behaviour rather than character, and finished in ten minutes. That version can be taught in an afternoon, and it changes more than any policy.

They've got no one to ask. The person they'd naturally go to for help is now the person they report to, and the last thing they want is to look like they can't cope in front of them. So, they guess, and hope, and don't mention it.

Why the timing matters more than it used to

There's a change coming that turns this from a development topic into a commercial one.

Employment law is moving toward much shorter qualifying periods. From January 2027, protection against unfair dismissal is expected to begin at six months' service rather than two years.

What that means in practice is that a business now has roughly six months to work out whether a new person is right for the role. And working that out doesn't happen by itself. It requires a manager who can notice a problem in month two and say something about it — clearly, early, and in a way the person can actually act on.

A manager who avoids that conversation until month eighteen isn't just storing up a performance problem. They're using up the window in which the situation was still straightforward.

Manager capability has quietly stopped being a nice-to-have.

What actually helps

I'd resist the urge to send someone on a course as the first move. Not because training doesn't work — it's most of what I do — but because it works far better once these three things are in place.

Write down what the job is. Half a page. What their responsibilities are and where it stops, what good looks like in six months. Most first-time managers have never had this and are visibly relieved when they get it.

Give them somewhere to take the hard questions that isn't you. A peer in another business, a coach, a mentor — someone they can admit confusion to without it feeling like a performance review.

And expect the first difficult conversation to be uncomfortable. It will be. The aim isn't for it to go smoothly, it's for it to happen at all, and for them to see afterwards that the world didn't end.

What this doesn't tell you

Whether a particular person is struggling because of the role, the support, the fit, or something else entirely isn't something an article can diagnose. Some people genuinely don't want to manage, and discovering that early is a good outcome rather than a failure — for them as much as for the business.

What I'd say with reasonable confidence is that "they'll pick it up" is not a plan, and that most first-time managers who are struggling are struggling with something quite specific that nobody has named yet. Naming it is usually most of the work.
