The Supervisor Is the System: What I Learned Running a Machining Operation

Written by Karil Reibold, CEO | Jun 10, 2026 4:00:01 PM

Long before I joined WorkWell, I ran operations.

I was COO of an advanced machining company which included precision work and skilled trades. The kind of environment where the people on the floor aren’t interchangeable, and everyone knows it.

We took injury prevention seriously. We pre-built setups and modified equipment. We did things responsible operators do to reduce physical burden on skilled workers.

And injuries still happened.

When they did, the impact wasn’t just a claim. It was a production schedule that didn’t hold or a delivery that became a difficult customer conversation. A shift that couldn’t be filled because the skill that walked out with the injury wasn’t waiting on a bench to be called in.

Early intervention wasn’t a tool I knew existed. If something was building, it built until it broke. It wasn’t until I joined WorkWell that I connected the dots on what was missing. And I’m still connecting them.

What I didn’t know then

Looking back, we weren’t missing a program. We were missing two things that have to work together: a supervisor who knew what to do, and a path for the employee when something was building.

Skilled machinists don’t report discomfort easily. The culture is to work through it. Push through the soreness. Adjust your grip. Find a way.

Supervisors saw it happening. They noticed when someone was moving differently, slower than usual, when something seemed off. But noticing was where it ended. There was no framework for what to do, and no path for the employee that felt appropriate for what seemed like a minor shoulder complaint. Reporting a formal injury felt excessive. Doing nothing felt easier.

So nothing happened until it did.

Awareness without access is just observation

This is what I’ve come to understand at WorkWell: the supervisor and the onsite clinic are not separate parts of an MSK strategy. They are two halves of the same system.

The supervisor notices. The clinic is the path.

Without both, the window to injury prevention closes regardless of intentions. A supervisor who sees something but has nowhere to direct an employee can only observe. And a provider who is available but never called upon can’t deliver the value they’re there to provide.

When both work together, something different happens. An employee mentions their shoulder has been bothering them. The supervisor knows what to say and where to direct them. The provider is accessible and familiar, not an offsite clinic that requires an appointment and causes half a day away from the floor. The employee goes. The issue gets evaluated early. The window stays open.

That handoff, supervisor to provider, observation to action, is where early intervention actually lives.

Why the onsite clinic changes the equation

In my machining environment, even if a supervisor had known what to say, there was nowhere low-stakes to send someone. The only options were formal: file a report, see a doctor, go offsite. None of those feel proportionate when your shoulder is sore, but you can still do your job. So employees said nothing. Supervisors said nothing. The ache became an injury.

An onsite clinic removes that friction. When a provider is physically present in the work environment, getting something looked at is no longer a formal event. It becomes as natural as stopping someone in the hallway. Employees grow comfortable with the provider over time. Early reporting stops feeling like an admission that something is wrong and starts feeling like what a well-run organization does.

That comfort builds through repeated low-stakes interactions. The provider who checks in on the floor. The supervisor who normalizes early reporting. The employee who goes and comes back without disruption. Each moment builds the trust that makes the next one more likely.

What I wish I’d had

We were doing the right things on equipment and setup. We cared about the people on our floor. But we were missing the two things that make early intervention real: a supervisor who knew what to do when something was building, and a provider onsite who made it easy to act on it.

Those two things together change the trajectory. Not because work becomes less demanding, but because the organization stops waiting for problems to become injuries.

In a skilled trades environment, what’s at stake when that prevention window closes isn’t just a claim. It’s a production schedule. A customer commitment. A skill set that takes years to develop and can’t be quickly replaced.

Supervisors are standing in that window every day. Whether it stays open depends on whether they know what to do when it matters, and whether there’s somewhere to go when they do.
