Your best welder might be a terrible supervisor.
That doesn't make them a bad employee. It means welding and managing people are two different jobs, and being good at one doesn't automatically prepare someone for the other.
But look at how we promote people. Someone knows the equipment, hits their numbers, helps everybody else, and shows up when we need them. We want to reward that. We also need somebody to run the department.
So we hand them a title, give them a team, and expect them to figure it out.
Then we're frustrated when they avoid difficult conversations, do everyone's work for them, or go from being everybody's friend to trying to prove they're the boss.
What did we actually teach them to do?
Knowing the work is only part of the job
A strong technical employee can usually recognize good work. That doesn't mean they know how to explain expectations to someone who doesn't have their experience.
They may know exactly how to fix a problem themselves. Teaching someone else to solve it takes a different skill. So does addressing a missed deadline without turning the conversation into an argument, or telling a former peer that something needs to change.
Those are things we can teach. But first we have to acknowledge that they're part of the job.
The same thing happens to business owners. You start a business because you're good at something. The business grows. Eventually you're responsible for a group of people, and nobody ever taught you how to manage them either.
Now you're doing your job, answering everybody's questions, fixing mistakes, and wondering why nothing happens unless you're involved.
Give people something more useful than a title
Before you promote someone, ask whether they actually want to manage people. Wanting more money or a chance to grow doesn't necessarily mean wanting responsibility for someone else's performance. We need ways to recognize strong technical employees without making management their only option.
If they do want the role, tell them what changes. What decisions can they make? What work should they stop doing? What needs to come to you? What does success look like beyond getting today's orders out the door?
Then practice the parts they're going to need help with.
Have them explain an assignment back to you as if you were a new employee. Walk through a conversation about repeated late work. Talk about what happens when their friend on the next shift asks for an exception.
It's a lot easier to work through that before they're standing in front of an employee trying to figure out what the hell to say.
Start with habits they can actually use
Clear expectations are a good place to start. What needs to be done, by when, and what does acceptable work look like? If the new supervisor can't explain that, the employee is already at a disadvantage.
Give them a regular opportunity to check in with their people. It doesn't need to be an hour-long meeting. A short conversation about what's going well, what's getting in the way, and what needs attention can catch a problem while it's still manageable.
Teach them to give feedback when it matters. Not three months later at a review. Not after they've gotten so irritated that the conversation comes out sideways.
And have them write down what was agreed. Who is doing what? What support is needed? When are we checking back? Nobody should leave with a completely different understanding of the conversation.
Those habits need support from the person managing the new supervisor, too. You can't tell someone to delegate and then criticize every decision they make without you.
If you're getting ready to promote your best employee, look beyond whether they can do the work. Ask what they'll need to lead the people doing it.
Then make teaching them part of the promotion.
