Why Good Workers Don’t Always Make Good Supervisors 

One of the most common leadership mistakes I see in businesses we work with, and in my time in the Police, is promoting the best worker into a supervisory role and assuming they will naturally become a great leader. 

It makes sense on paper. 

They’re reliable. 
They know the job. 
They work hard. 
They’re respected by their peers. 

So, when a supervisor position becomes available, they’re often the obvious choice. 

Unfortunately, being good at the job and leading people are two very different skill sets. 

Technical Skills vs Leadership Skills 

A skilled tradesperson knows how to complete the work. 

A supervisor needs to know how to help others complete the work safely, consistently and efficiently. 

That requires an entirely different set of skills, including: 

• Communication. 
• Coaching. 
• Planning. 
• Conflict resolution. 
• Performance management. 
• Decision-making. 
• Emotional intelligence. 

None of these skills develop automatically with experience. 

The Hidden Cost of Promotion 

Many new supervisors continue doing the technical work they are comfortable with because they lack confidence in managing people. 

As a result: 

• Problems aren’t addressed early. 
• Employees receive little feedback. 
• Safety conversations become rushed. 
• Performance issues grow. 
• Teams become frustrated. 

The organisation then blames the supervisor for failing to prepare them. 

Leadership Is Learned 

The best supervisors I’ve worked with weren’t born leaders. 

They were coached. 

Someone invested time in helping them understand how to communicate, solve problems, manage conflict and support their team. 

Leadership isn’t about having all the answers. 

It’s about helping others succeed. 

What Can Managers Do? 

If you’re promoting someone into a supervisory role, don’t just hand them a new title. 

Give them: 

• A structured induction into leadership. 
• A mentor. 
• Regular coaching sessions. 
• Clear expectations. 
• Time to develop. 

The investment you make in your supervisors today will shape the culture of your business for years to come. 

Michael’s Leadership Reflection 

The next time you’re promoting your best worker, don’t ask, “Can they do the job?” 

Ask, “Have we prepared them to lead people?”
