Your best worker may not be your best supervisor

Promoting the best-performing employee seems like a sensible way to fill a supervisory position. The person already knows the business, understands the work and has built a good relationship with customers. For a small business owner who cannot afford to bring in an experienced manager, promoting someone from within is often the easiest option. But the move does not always work out as expected.

An employee who was once responsible for completing their own tasks must now make sure everyone else is doing theirs. They have to allocate work, follow up on deadlines, deal with mistakes and address employees who are not pulling their weight. The adjustment can be difficult, particularly when the new supervisor is managing people who were previously their colleagues.

In some businesses, the owner ends up dealing with the same problems as before. Staff still come directly to them with complaints, work is not completed on time and the new supervisor struggles to take charge. The issue is not necessarily that the employee lacks ability. They may simply have been promoted because they were good at their previous job, without considering what the new position would involve.

The move from doing the work to managing it

Consider a small vehicle repair workshop. One technician has been with the business for four years. He knows the equipment, can diagnose difficult mechanical problems and regularly finishes his work on time. Other technicians often ask him for help. When the owner needs a team leader, he is the obvious choice.

But the new position comes with responsibilities that were not part of his previous job. He now has to allocate repair work, check which vehicles are waiting for parts, follow up on delays and make sure customers receive their vehicles when promised. He also has to address a colleague who repeatedly submits incomplete job cards.

The technician may know exactly how to repair a vehicle, but managing the workload and dealing with staff problems are different responsibilities. Instead of handing him the entire workshop to manage from the first day, the owner could start by giving him responsibility for two technicians. They agree on how work will be allocated, how delays should be reported and which decisions he can make without approval.

The owner checks in twice a week to discuss the workload and any problems. This gives the new team leader time to adjust while allowing the owner to see how he handles the responsibilities. It also makes it easier to identify problems before they affect the entire workshop.

Give the new supervisor a clear starting point

Internal promotions can create confusion when nobody explains what has changed. Employees may continue going directly to the owner, while the new supervisor is unsure how much authority they have. The owner needs to make the arrangement clear to the whole team. Employees should know who allocates their work, who checks progress and who they report to when something goes wrong.

The first month is a good time to establish these routines. During the first week, the new supervisor should meet the team, review outstanding work and understand what needs attention. In the second week, they can start allocating tasks and checking progress. By the third week, they should be dealing with routine staff issues and following up on missed deadlines.

In the fourth week, the owner and supervisor can review how the team is performing and discuss where further support is needed. The owner should also explain which decisions the supervisor can make. They may be allowed to allocate shifts, organise daily work and address late arrivals, while salary increases, formal disciplinary action and dismissals remain with the owner. A short weekly meeting is usually enough to discuss unfinished work, customer complaints and staff issues. The aim is to give the supervisor responsibility without leaving them to work everything out alone.

The difficult part: managing former colleagues

One of the first challenges for an employee promoted internally is having to correct someone they previously worked alongside. A new supervisor may find it uncomfortable to tell a colleague that their work is not good enough. They may worry about damaging a friendship or creating tension in the team.

Take the workshop example. A technician has missed three repair deadlines. Other employees have had to help finish the jobs, and customers have been waiting longer than expected. The new team leader cannot keep ignoring the problem. The conversation should start with what happened. Instead of accusing the employee of being lazy or unreliable, the supervisor should explain which jobs were late and how this affected the workshop.

They should also give the employee an opportunity to explain. Perhaps the workload is too high, parts are arriving late or the employee is struggling with certain repairs. Once the reason is understood, they can agree on what needs to change and when progress will be reviewed.

If the problem continues, the supervisor should keep a record and involve the owner where necessary. It is important that the new supervisor understands they do not have to handle every serious staff matter alone. However, they cannot pass every uncomfortable conversation back to the owner either.

Is the team performing better?

After the first month, the owner needs to look beyond whether the new supervisor is keeping busy. The question is whether the team is getting its work done more effectively.

There are four areas worth tracking:

• Work completed on time: Are jobs, orders and tasks meeting their agreed deadlines?

• Team errors: Are mistakes increasing or decreasing?

• Unresolved staff issues: Are problems being dealt with, or are the same complaints coming back?

• Owner intervention: How often does the owner still have to step in to organise work or handle routine staff problems?

These figures should be compared with the month before the promotion. The owner should also speak to employees to find out whether work is being allocated fairly and whether instructions are clear. If the owner is still managing most of the team's daily activities, the new supervisor may need more guidance or a clearer understanding of the role.

Not every strong employee wants to manage people

There is another issue that small business owners should consider: some employees simply do not want to become supervisors. A good technician may prefer working with equipment rather than managing staff. A strong salesperson may enjoy dealing with customers but have little interest in monitoring other employees' performance.

That does not make them less valuable to the business. Owners should find other ways to recognise good employees, whether through better pay, additional technical responsibilities or opportunities to train new staff.

For employees who are interested in management, giving them responsibility for a shift, a small project or training a new colleague can be a useful first step. Promoting someone should be about the job they are moving into, not just the work they have already done.

Common mistake: Promoting the employee who produces the most work without considering whether they can manage other people.
